Barry Allen sighed as he was in the third hour of a 6 hour car trip, wondering for the millionth time why he had let his loving wife talk him into using a stupid car when he was the fastest man alive. 
even as he cruised at a solid 55 MPH on the highway, it was like a slow walk to the man who when he wasn't being a CSI or a loving husband, happened to be the flash. 
Of course he knew WHY and had agreed with her at the time, that Barry Allen managing to make it from Central city to Gotham in under 10 minutes would of raised all sorts of flag, but still. He hadn't even enjoyed the conference he'd been forced to go to by his supervisor, the highlight of the 3 day event had been hanging out with Batman.
Still it was over with and he vowed to find a way to squirm out of the next conference, even if he had to let a super villain or two out of jail. (Ok, he wouldn't actually do that but it was fun to picture on the long drive.)
Still there was a highlight on taking the long drive, it would give him a legitimate excuse to stop by and check on his favorite (well ok, only) nephew though his marriage to Iris: Wally west. 
The boy had made a habit of spending any and all vacation time he could get (within reason) coming out and visiting them and while it made things a little harder on Barry's double life, seeing the freckled smiling face of the boy always made up for the slight inconveniences.
The only downside to making the trip without Iris (who had been kept busy with work) was there was no one to act like a filter between Barry and Rudy west, Wally's very unpleasant father who made his dislike of Barry well know while also never QUITE insulting Barry and giving him a excuse to put the bastard in his place. Barry knew that while Rudy would sight Barry's low income and long work hours as reasons that Barry might wanna find a 'real job', it was more the fact Wally looked up more to Barry then his own father that had turned the man more and more sour.
Barry also couldn't be totally sure, and wally wouldn't talk about it but since the poor boy had started bed wetting again Barry was convinced Ruby had started abusing his son, Mentally if not physically and disguising it as a spanking helped little bed wetters stop (a belief Barry did not follow)
Still he was sure wally would light up when Barry swung by as a surprise and if it just happened to ruin Rudy's day, gee, wouldn't that be a shame. 

Rudy was home alone, having a beer (or two or three) and watching a game when there was a knock at the door. he started to call out for his wife Mary to go and answer the door before recalling where she was and got up out of his lazy-boy , cursing slowly as he spilled some beer on his plain white t-shirt.
"Hold your damn horses! I'm coming!" he called.
Already in a bad mood, it got worst as he saw who was at the door and sighing like he had the WORST luck, he opened the front door, sipping his bee that was still in his right hand. 
"What do YOU want?" Rudy asked. 
"Hi to you too Rudy." Barry said dryly , looking at his watch.  "Little early for a brewski isn't it?" 
"Don't tell me you drove all the way here to give me shit for enjoying a cold one on my day off." Rudy snorted. the booze took away what little filters he had and well, it wasn't like Iris or Wally or Mary were there to give him any shit. 
"..I'm actually on my way back from a conference, and thought I'd drop by and see wally for a bit. and maybe enjoy your charming company." Barry said, then added. "Though PLEASE tell me you haven't been drinking in front of him? That's a bad example Rudy." 
"Well Barry, when I want you to tell me how to raise my son I'll ask. Maybe I could give you advise on how to raise YOUR kids..Oh wait." Rudy said, smirking then taking a long drink, not aware the man he was insults could of stranded him in the middle of a city in just his boxers because he'd even know what was happening, and that Barry was fighting the urge to do so at this moment. "in any case, Wally's not here. He's in the ER with his mother. the little Klutz fell down the stairs and pretty sure he broke his ankle." 
"Wait what? If he broke his ankle why aren't you-" Barry started, anger and fear mixing. 
"Kid shit his pants and smelled something awful, so I stayed behind. wasn't room for me in the ambulance." Rudy paused and anther smirk. "and since I've been drinking I didn't wanna drive, I thought you'd appreciate that Barry." 
"..How did Wally fall down the steps?" Barry asked, voice going low as something about the attuide and smugness in the man's voice had Barry worried. 
"Stupid little dork tripped over his own pissy diaper when it hit the floor. you know he's wearing 24/7 now? started pissing himself at school!"
"...Rudy I happen to be VERY good at my job, and I'm going to drive over to the ER now and talk with Mary and see how wally's doing. If there's something you wanna tell me now, it'll help you out in the long run." Barry said, pushing his way into the house and the smile vanished from Rudy's face. 
"I..I don't know what your-" Rudy stammered out, looking anywhere but at Barry now. 
as much as Barry wanted to get the story out of Ruby, maybe go a little batman on him, his biggest concern was getting to wally before Mary, ever the dotting wife could convince Wally to keep the truth to himself.
"This is NOT over Rudy. Think about what I said about helping yourself. It IS what your best at." Barry said and stormed out. 
Rudy gulped and slumped to the floor, wondering if it might of been time to call in some vacation time and take a little trip before Barry came back.

Barry's knuckles were going white as he drove to the nearest hospital, he wanted to just zip over but having the flash show up for a kid only Barry should know would of been against secret identity rule number one. 
Still the time wasted on getting a parking spot and having to get directions irked him to no end when he knew he could of searched the place in less then 1.5 seconds. 
Finding Mary sitting outside of the OR, he walked over to her and was silently counting down in his head as she looked annoyed and mad she was waiting on her only child to get out of surgery then worried.
"Barry, what are you doing here?" she asked, shocked and sounding a little worried. 
"I went to stop by for a visit and Rudy told me what happened.." Barry said, then added. "How's Wally?"
"It's taking longer then they thought, they had to stop and change his diapers because he shit himself again. Like it wasn't taking long enough." Mary said and rolled her eyes then caught herself. "I mean, I just.. I'm annoyed he hurt himself is all. he should be really more careful where he puts his toys." She added fast.
Already spotting the difference in stories, Barry just rolled with it. 
"Yeah, Rudy said it was a toy truck I believe. " Barry lied., hoping to catch her in the lie. 
She looked confused for a second, then nodded. 
"well, since he's started needing diaper ALL the time and his friends at school have shunned him, he's gone pretty infantile." she said. 
"..Mary with this happening at home you know child services will be investigating right? So as a CSI my advice to you is to make sure you tell the truth. whatever it may be." Barry said, crossing his arms across his chest.
he didn't have the broad shoulders of Batman or superman, but he  a twig either and cut a imposing frame. 
"W-what do you mean by that?" She asked. 
"Rudy told me Wally tripped down the stairs because of his diapers, you told me a toy, I'm damn good at my job Mary but it doesn't take a genius to guess what happened. I SAW the bruises last time me and Iris had him." Barry said flatly.
"I-I swear, it's not me Barry!" Mary said, keeping her voice low and looking around the waiting room now.  it was only the two of them and it was clear she was scared now. "if I don't go along with it Rudy wi-" She started to add, But Barry cut her off. 
"Iris and you went swimming together not too long ago and she would of told me about any bruises. If Rudy was mentally harming you then you would of taken this chance to out him. So drop the victim act." 
"..Oh like you know what it's like, having a promising young boy end up pissing himself and shitting him and looking at his own parents with disdain because he'd rather be with his aunt and her side piece!" Mary snarled.
"watch your tone. Look, I'm willing to help you and Rudy out with this, stay out of jail because I don't want wally to have to visit you in prison..but the price is going to be simple and clear." Barry said. 
"Let me guess, you need a loan?" Mary said, a smug smirk on her face reaching for a check book.
"I don't want your Money. I want wally somewhere safe. Me and Iris are going to take custody of him and your NOT going to contest it."

Mary argue, she called the house to tell Rudy about it but he wasn't answering having already taken off, leaving a note for Mary on where to find him and in the end Barry had his way. With Mary taking a taxi back home Barry cleared that he was the impending legal guardian and then located a pay phone. Calling Iris as he wanted on Wally to recover after his surgery to tell her everything that had happened, The only part of the whole thing she disagreed with was Barry letting them off Scott free. 
After that he put in a call to a few friends in the DA and family court back in Central city and got assured the whole thing would be settled with minimal fuss.

Wally giggled softly as they wheeled him out of recovery. he was naturally in a wheelchair and dressed in a green gown that fluttered in the AC of the building revealing the thick green tinted diapers he was wearing and his left foot had a sock on it while the right had a thick off white cast around it. The boys freckles stood out as he smiled, his orangish red hair a mess and his eyes totally glazed over. 
"Unca Barry! Hiiii!" he giggled and for a second went to get out of the chair before a nurse gently pushed him back down.
"Lizard queen, we talked about this, you can't walk yet." she said with a smile on her face and a amused tone. 
"..Lizard queen?" Barry asked.
"Your nephew apparently has next to no tolerance for pain killers and well.." the blond nurse started but was cut off by Wally tossing his arms up.
"I AM THE LIZARD QUEEN! FEAR ME!" He giggled and coo'ed.
Barry snorted and nodded.
"I see. well is her Majesty ready to be signed out yet?" he asked, coming over and patting a head on wally head, a paternal gesture to most, and it was head, though he was also looking for lumps or bruises.
"we'd like to keep him for a little while longer, at least until he's more lucid and well, his clothes are clean and out of the landry. I'm sure the lizard queen would prefer not to drive around in just a diaper." the nurse chuckled."besides, you might wanna go and stock up on some item's Mr. Allen."
"Heh, touche. Wall man, you gonna be ok with the nurse while Uncle Barry goes and gets some supplies for you?"
"I can count to purple." Wally giggled and held out his arms for a hug.
"Oh wow, thats VERY talented!" Barry chuckled and kneeled down, Hugging the smaller boy gently and then feeling Wally slump and pulling back, alarmed.
"Relax Mr.Allen, it's the drugs, he's just been sleepy. Someone will stay with hi in his room to watch him." She said, putting a reassuring hand on Barry's shoulder. 
the statement was made to sound like it was because of his drugged state, but the underline was that they were making sure Mr. and Mrs.west didn't come back.
"I'll be back as fast as I can." Barry said and took off.

Getting in the car he drove out to a field where he could park it and felt assured it would be left alone for at least a few minutes.  Sliding out from behind the wheel and hitting a special ring he wore out popped a compressed version of his costume and making around in a blur, he quickly suited up and then put his clothes in the back seat of his car. 
Experience had taught him that when it came to what he was likely going to need to to to pack a duffel bag for wally, his normal clothes wouldn't of made it. 
in the micro seconds it took him to get to the west household a check check confirmed that the doors were locked and not wanting to give them any chance of coming back and getting him or Iris in trouble Barry backed up a few feet in their back yard where the sight of the flash wouldn't be seen(or at least not as easily) for the 2 seconds it would take to ready himself for this. 
One of his more useful skills could also be terribly destructive if he wasn't careful so taking a deep breath he readied himself then started to dash at the back door, willing his molecules to vibrate just right and he was able to phase though the door clearly, not blowing it up like he'd done when he'd first learned this trick.
Racing up the stair Barry helped himself to a duffel bag and filled it with some of Wally's clothes, recalling his favorite t-shirts and pants, and as well as the boys gaming devices and a few of his action figures and books, and of course the teddy bear wearing a costume just like Barry's that they'd made at a make bear last year. 
with the duffel bag full Barry helped himself to a back pack now, and filled it with the thick, over the top babyish diapers the wests had gotten their son, that while cute and made Barry warm up to a idea he was getting, made him fume as it was clear they had been trying to shame the boy out of his accidents. 
he also helped himself to the changing supplies and noted the extra steanght diaper rash cream and made a note to ask the nurse about if wally had a rash when he got back. 
Giving the room one last look over, Barry slowed down enough to be hit by the smell of the diaper pail in the corner and grimaced, smell molecules couldn't affect him when he was moving at super speed but they tended to come back with a vengeance once he slowed down. 
Looking in the diaper pail the thing didn't even have a bag in it and was set where the sun was sure to hit it as well, and had marking on the inside showing how full it had to be before Wally would of been allowed to change it. 
"..Should of smashed the bastard into a pulp when I had the chance." he growled, then sped back up, leaving the room.

he simply unlocked the back door and placed the bags on the grass as they wouldn't of survived the trip though the door then went back in and re locked it and zipped back though it before packing the bags in the car and changing back to his normal clothes, the whole thing taking all of maybe five minutes. 
Getting behind the wheel of the car, he fished out a JLA commutator he kept with him at all times (which all Justice leaguer's were required to do, though some like Green tended to forget) and made a call to Batman, for the plan he had to make wally happy and settle in at home and life with the Allen's, he was going to need a bit of finical help.
Once the situation was explained Bruce was only too happy to help though recommended that they take Wally's recovery slowly, but warned Barry he wouldn't hold back if the west's happened to end up in Gotham city. 

Barry took Batman's advice and extended his leave, even after wally was discharged from the hospital they didn't go to Central city right away, Barry taking the sullen and emotional boy to several road side attractions on the drive back. 
wally had been unwilling to confirm that he'd been pushed down the stairs at first, even when it became clear that his parents had admitted to at least some of it. (as it turned out he'd been pushed down the stairs twice before this.) 
The worried about diaper rash had been confirmed and while Wally whined that he could look after his own diaper changes, Barry was having NONE of that and insisted on changing his nephew, teasing the blushing boy about the freckles on his butt that became more clear as the rash faded. 
Wally also was embarrassed at first but grew to like how Barry insisted on carrying the boy instead of making him use his crutches, his thin and light frame made it easy enough. 

Getting home to central city Barry was all smiles and wally was actually more relaxed and ok, even eager to see Iris as they pulled up, who was in fact waiting in the drive way for them and rushed out.
"Wally! How are you? Are you ok?" She asked, showering the boy in hugs and kisses and fussing over him as he got out of the car on his crutches, having insisted on not being carried into the house. 
"I'm fine aunt Iris, just a little sore. Aunt iris I'm.. Iris.. Barry help!" Wally giggled and then gave a mock plea for help.
"heh, Maybe let him get in the door before you shower him with love?" Barry suggested, getting his bags and Wally's out of the trunk of the car.
"Never!" iris chuckled but did back up, while adding. "Just so you know little guy, expect lots of that from me." 
"heh, well I suppose I'll allow that." Wally said, grinning like a goof ball as he made his way towards the front door. 
Iris and Barry exchanged grins, as if to say 'that's cute, he thinks he has a choice!'
getting the wall man inside Barry put the bags down by the door and swept Wally off his feet. 
"wally, there's a little something that me and your aunt have been meaning to talk with you about, and we think it's going to help your recovery a lot." Barry said, heading for a room on the first floor that had been converted into wallies new room since they didn't like the idea of him having to go up and down stairs. 
"Oh? what is it?" wally asked, not even fighting it as he was carried on Barry's hip, his thick diaper puffing out his cargo shorts. 
"well, we think a bit of regression therapy would help with your recovery so on that note.." Barry said, and opened the door to Wally's new room.
The wall's were painted flash red with little flash symbols on the walls every few feet and there was a light yellow plush carpet on the floor. 
what caught Wally's eyes though as the little guy's jaw dropped was the large changing table and a crib in the room, as well as a large toy chest. 
"So.." Iris said coming up and kissing Wally's cheek. "what do you think of your nursery?"
