Avengers (Problematic)

AN: I know I said I was going to do a couple more Halloween ones, but they weren't coming out how I wanted. So here's this one instead! I don't know what it is but its something! Also, the video is for the end, but if you chose to watch it first, that's up to you. I'm sure you'll appreciate the dead meme.

I'll try and get one up for Thanksgiving but I seem to be having problems with how I want it to end and the direction it's going in. But I'll try my best!

"No! No! No! This is bad! This is really bad!" You pace back and forth in the lab, horrified by the effects of what your serum has caused on your body. Granted, while the serum worked, it worked a little too well. When you had tested it on the rats it worked fine, everything went as it should. But since the serum was going to be used on people, it needed to be tested on something bigger. Why not test it on yourself?

What you didn't realize, or more or less forgot to do— was check up on your test rats a couple days later. What had happened was they went from adults to fuzzies, and finally pinkies. By the time you had noticed, it was too late, you had already injected yourself with the serum and passed out. Now here you were, scared and the size of a ten-year-old, unsure how to reverse its effects.

"T-Tony! Bruce!" You cry out, tears brimming in your eyes.

"Hey, Yn. What's up? You sound... Whoa!" Bruce stops in the doorway when he sees you, his jaw drops as he gaped like a fish. "Y-Yn! What happened?! You're- you're so small!"

"Something went wrong! H-help me!" Bruce rushes to you.

"What's with all the- Holy shit! Yn?! What did you do?!" You wipe your eyes with the back of your hand, trying to keep the tears from slipping out as Tony enters the room.

"R-remember that cosmetologist that wanted to commission me for an anti-aging serum?" Tony closes his eyes tight.

"Yn, please say you didn't."

"...I did..."

"God damn it..."

"Why did you test it on yourself?" Banner asks.

"I-I needed a bigger test subject..."

"Yn, that was stupid of you!" Stark yells.

"I know it was...!" You burst into a fit of sobs.

"Tony!"

"What? You know I'm right! It was a stupid decision! How many PhDs does she have? And this is how she uses them? It's probably the stupidest thing she's ever done!" Your sobs grow louder.

"TONY!" Bruce yells, he hugs you close to him in an attempt to calm you down. "Did it ever occur to you that this serum may have also affected not just her body- but her mind as well? Her brain could be becoming childlike!" Stark freezes as he stares at your tear-stained face, you stare up at him with a quivering lip and snot dripping from your nose. He rubs the back of his neck in a guilty way as you bury your face in Bruce's chest, gripping his shirt in your hands.

"I-I'm sorry, Yn. I didn't realize..." he gets down to your level and sighs. " You're not stupid, it wasn't stupid that you needed to test your project... We'll figure this out and make you 'You' again... I promise..." you peek at him from Bruce's shirt and nod slowly.

"O-okay..." You whimpered.

"Where's the equation to your formula for the serum?" You point to the stainless steel table in the center of the room.

"I-I can't reach it anymore... but it's in the center of the table n-next to the jellyfish tank..."

"Jellyfish?" Bruce looks down at you, brows furrowed. "You used a jellyfish for this?" You nod.
