This is a kid fic. Sorta. Anonymous guest asked for a story where Barry is a kid and Oliver has to take care of him. This is what my mind came up with. It took a totally different turn then I intended it... I hope this was what you meant. It also turned out longer than my usual fics.

Sorry if they're wayyy OOC. Fisher is also an OC I made up for the sake of the story.

How did he end up having to take care of a kid? He's never even taken care of a pet, much less a kid, and if he's honest with himself- he has no idea what he's doing. Oliver just hopes the kid sleeps through the day, until they find a way to turn Barry back.

How this happened is unbelievable. He remembers Barry came to Starling City to catch a metahuman (No. Suspect. Oliver refuses to call them metahumans) . One of Central City's criminals seemingly ran to Starling City after getting spooked by the Flash. The criminal, Fisher they learned his name, is clearly an idiot if he ran to the city with the Arrow patrolling the streets. So Flash came to Starling City, and since it was surprisingly quiet, Oliver decided to help the scarlet speedster. Fisher can apparently change people's ages. Why anyone would have that power is a mystery and simply a pain in the ass. Especially since the criminal changed the Flash into a little kid. Arrow had quickly subdued the man and turned his attention to Barry. The kid, an actual kid now, had luckily been unconscious. After much debating, one heated argument with Felicity, and a phone call to Central City; Oliver finally went home and took the still unconscious kid with him. They couldn't exactly do a full examination of Barry since they did not have the equipment to check the vitals of a speedster. Of course they made do and so far it seemed the kid was fine and healthy.

"Dad?" A small, scared voice called out from Oliver's room. Shit. So much for sleeping the entire day away. The voice came again, louder this time. This time Oliver reacted, walking to the room. He found a very young, very scared looking Barry staring at him from the bed.

"You're not my dad..." Barry mumbled, twisting the blanket he was under between his tiny hands. He couldn't have been older than maybe four. Oliver gave him what he hoped was a friendly smile.

"No I'm not. Do you know who I am?"

He only got a head shake as a response. Great, that means Barry probably doesn't remember anything. Suddenly the kid fell backwards, throwing the covers over his head, hiding under the blankets, the international sign of a terrified kid. Oliver moved closer to the bed, unsure of what to do. He gently sat down next to the lump under the covers.

"Its okay. I'm a friend," Oliver said. There were a few minutes of silence, before Barry pulled the blankets down so only his eyes could peer out from under the covers.

"No you're not," Barry said quietly, "I don't know you. How can we be friends if I don't know you?"

He smiled, laughing softly; "You got me there, kid. I'm Oliver."

Another silence settled between the two, during which Barry still didn't move from under the blankets. Oliver tried to relax, not wanting to scare the kid further. Caitlin had said that they will try to figure something out at Star labs and that in the meantime Oliver had to make sure Barry's fine until Joe could come and get him. Unfortunately it will take the detective a while to make the trip from Central to Starling.

"My mom says I shouldn't talk to strangers," Barry said and instantly frowned, "Where's my mom?"

The question sent a sharp pain to Oliver's chest and his smile dropped. Barry picked up on his expression and instantly tears gathered in the kid's eyes.

"Where's my mom? I want my mom!" The kid started crying, demanding to see his mother. Oliver felt himself start to panic. How do you tell a little kid that his mother is dead? Has been for years. And that his father is in jail for her murder? Barry continued to yell, tears streaming down his chubby child cheeks.

"She-She's not here. She asked me to look after you while she's gone," Oliver lied, trying to swallow the lump in his throat. Barry had turned so his face was buried in the pillow and when he spoke his voice came out muffled; "Wher's she? Why'd she leave me?"

Not knowing what to say, Oliver instead put a timid, comforting hand on Barry's back. The kid was small, even for his age. The action seemed to spur something in the kid, because suddenly Barry turned and launched himself into Oliver's chest. A surprised rush of air left Oliver's lungs. Without giving it much thought he pulled the kid into his lap. Barry clutched Oliver's shirt between his hands, burying his face in Oliver's chest. Carefully one hand came up to rub Barry's back soothingly, while the other curled around the kid to keep him from falling. He sat listening to the kid sob, murmuring words of comfort. Not knowing what happened or where your parents are must seriously be scaring the kid. Eventually the crying subsided, replaced by hiccups. The kid rubbed the material of Oliver's shirt, where his hand still held tight, between his fingers. Not wanting to start anything else, Oliver remained quiet, still rubbing Barry's back. The sound of Barry's sniffing and a distant car horn were the only thing in the room.

"I'm hungry." The statement was so absurd after that, that Oliver could only stare at the kid. Finally breaking out of his daze, he helped the kid off his lap.

"Yeah, sure. I'll make you something to eat." Oliver said, smiling at Barry. Barry's eyes were red and puffy from crying, and he pulled up a small fist rubbing at his eyes. The patch of shirt covered by tears and snot stuck to Oliver's chest, but he didn't mind. At least the kid finished crying. He stood up and started walking away when a tug on his shirt stopped him. He turned to look down questioningly at Barry.

"You're really my friend?" Barry asked, looking hopeful.

"Yes." Oliver replied. The kid held up his hand with his pinky extended.

"Pinky promise?" The action was so unbelievably cute and childlike that Oliver could do nothing but lace his finger with the kid.

"Promise. Now let's get you something to eat." Oliver once again turned and started walking, making his way to the kitchen. He got to the living room when he felt something grab his hand. He looked down to see that Barry had grabbed his hand. The kid seemed happy to just hold his hand. The hand was so small compared to his own. It was also soft whereas his were calloused from years of using the bow. He felt weird, having something so innocent to take care off when he himself was so far from it. He almost felt guilty and maybe he should call Felicity to come and get the kid. Of course one look down into the kid's face made that feeling disappear. The kid looked so trusting, even though he sort of just met Oliver. Damn it. No one should look at him with such open trust or adoration. Sighing he decided on fixing the kid something to eat, before dealing with anything else. Suddenly a new problem arose; What do you give a four year old to eat?

Just when he had his phone out to call Felicity for help, the woman burst through his door carrying an arm full of groceries.

"Sorry! Sorry! I'm thinking we're beyond knocking plus I figured you need help," Felicity continued talking as she put all the groceries on the table. How she managed to not run into something or fall was beyond Oliver. When she finally turned to face him she spotted Barry, "oh! Hey."

Barry ducked behind Oliver, hiding from Felicity. His small body almost completely disappeared behind Oliver's legs. When Felicity tried introducing herself he only peeked his head out a couple of inches.

"No need to be afraid. Are you hungry? I bet mean man Oliver hasn't even given you anything to eat yet-" Oliver sent her a glare at that, "- but I brought snacks. Li-ike" Felicity turned to the bags, digging around and after a few moments of rummaging she pulled out a tub of ice cream, "Ice cream!"

"Like he's going to accept you, because you brought ice cream," Oliver said, rolling his eyes. To his astonishment Barry actually came out from his hiding place behind him and grinned. Felicity sent him a triumphant look. Right. Fastest way to a speedster's and a kid's heart; food.

"Well come here and let's see if we can't find bowls. I even brought chocolate sauce!" Felicity said. Soon they were both busy in Oliver's kitchen building their own sundaes. Naturally Felicity went all out and brought everything you can put on ice cream; sprinkles, chocolate balls, different kinds of sauce etc. Oliver felt a fond smile grace his face as he saw the scene unfold before him. Barry immediately warmed up to Felicity, which really wasn't that surprising considering how good they got along when they first met.

"Aren't you gonna get ice cream?" Barry asked him, staring at him from behind his huge bowl of ice cream. Oliver just hoped the kid wasn't going to have a sugar rush. A grown speedster was bad enough, but a four year old speedster on a sugar rush?

"Of course I am," Oliver replied moving towards the pair.

-TF-TA-

Oliver gave a low groan, stretching is aching limbs. That was the second movie Felicity and Barry roped him into watching. Felicity clearly adopted a little partner in crime. Whatever she suggested Barry would just back her up. No matter how strong willed he claims he is, he couldn't resist both of them giving him puppydog eyes. Thus how he found himself suffering through two disney movies with Barry on the floor with a pile of blankets and a mountain of pillows. Felicity is on the couch next to him. When he had sat down she immediately plopped next to him, pushing her feet under his thighs with her back on the arm rest.

Glancing at her now, he saw she had a soft smile on her face. He followed her line of sight and saw that Barry was fast asleep. She nudged his leg with her foot, pointing her head in Barry's direction. He frowned, giving her a questioning look. She rolled her eyes.

"He can't sleep on the floor," suddenly she got a mocking smile, "go tuck him in."

"No."

"Yes. Go!"

"Why can't you do it?"

"Queen."

"Fine," Oliver sighed, giving up after Felicity sent him an exasperate look. Standing up, he put the empty bowl of popcorn on the couch next to him. Wiping his hands on his jeans, he bent down next to the kid. Initially his intend was to wake him up, but looking at him now he didn't have the heart. Instead he gently scooped the kid up, carrying him bridal style. A few incoherent mumbles escaped, but other than that he was still fast asleep. Oliver could feel hot air waft over his collarbone with every breath Barry took. Arriving at his room he walked over to the bed. He somehow managed to balance the kid and pull back the bed covers. Gently putting Barry down, he pulled the covers over the small form. Staring at the kid's sleeping face he felt the urge do lean down and press a kiss to his temple. So he did. Oliver leaned down, gently running his fingers through Barry's hair and pressed a kiss to his forehead. He straightened up, making his way to the door. Casting one last look over the sleeping form, he switched the light off and made his way back to Felicity with a small smile he would deny ever having if asked in the future.
