Tony's panic attacks

Getting Loki'd

there was a boom, then a scream. it had the entire team skipping the elevator and racing up the stairs. why did Tony insist on working on dangerous things when Bruce wasn't home?

"Jarvis whats happened?" Steve ask as they reached the lab. it was full of smoke, it was leaking from around the door.

"I am unsure." Jarvis replied.

"Tony open the door." Steve said, knocking. the lights in the lab were out.

"no! go away!" Tony shouted.

"Tony open the door, or I'll kick it in." Steve added.

"or turn on the lights." Clint said. the lights flew on but Tony was no where to be seen, even as the smoke cleared.

"Tony?" Natasha ask. "where are you?" Natasha ask.

"I'm in the lab." Tony said. his voice was muffled now. Steve rolled his eye's and kicked in the door.

"split up and find him." Steve said.

"no need. he's in here." Natasha said, knocking on the bathroom door that was in the lab. "Tony, come out of the bathroom." Natasha said.

"no." Tony replied.

"Tony, come out of the bathroom." Clint groaned.

"get. Bruce." Tony ordered.

"why is something wrong? Tony if your-" Steve started.

"GET BRUCE NOW!" Tony screamed. Steve sighed. Phil pulled out his phone out.

"Dr. Banner, as sure as I am that you're busy, we have a possible code yellow and who knows what else. there was an explosion and now Tony has locked himself in the lab bathroom, demanding you." Phil said. "thank you." Phil sighed, hanging up.

"so?" Clint ask.

"he was already on his way back. he'll be here in ten minutes, five if he can get Happy to speed up." Phil replied.

"why doesn't he have his liscense?" Steve ask.

"rode rage and he perfers motorcycles. his is in the shop. besides, Tony pays Happy to drive us around." Phil replied. Steve nodded. they waited nearly ten minutes and Bruce ran up. he panted slightly.

"okay where is he?" Bruce ask.

"Bruce?" Tony ask from the bathroom.

"yes Tony. come on, open the door." Bruce said. the door opened slightly, Tony reached out and Bruce in quickly, slamming the door shut. the lights were out. "Tony why are the lights off?" Bruce ask. Tony whined softly.

"promise you're not going to laugh?" Tony ask softly.

"uh, first I want to know what you were working on." Bruce said.

"well remember how we were talking about maybe a happy Hulk?" Tony ask.

"yeah." Bruce replied.

"well I was working on that, not promise not to laugh." Tony said.

"fine I promise not to laugh." Bruce sighed. Tony flipped on the lights. Bruce stared shocked for a moment, then brought a hand up to his mouth to cover the laughter.

"you promised not to laugh!" Tony shouted. Bruce snickered and shook his head.

"oh my god. this is great. Tony how did this happen?" Bruce ask.

"I don't know! I thought I had some of Hulks hair but I guess I grabbed cat fur!" Tony shouted, his new cat ears twitching in frustration.

"thats so cute." Bruce grinned, watching his ears. "awe you have little tail too." Bruce teased.
