AN: In this story, the Avengers are still the Avengers, but they're younger. Everyone is mid-20s to early thirties(well except for Thor, of course) and Tony is the youngest.
"Stark! I am tired of this reckless behavior! What if we were called in right now and you were drunk?!" Steve yelled in Tony's face, not noticing how the man was beginning to shake.
"Relax Cap," Tony slurred slightly and grimaced at the volume of Steve's voice, leaving out "I'm not drunk, I'm just getting over a migraine."
"That's it! It's time for you to sober up," Steve screeched, grabbing Tony roughly and shoving him towards the sink.
"Stop. What are you doing?" Tony protested and struggled, but the stronger man ignored him. Steve threw Tony's head into the sink and turned on the water. By this time, the entire team, excluding Bruce, was in the kitchen, but there was not enough time to stop him.
"ROGERS! LET GO," Natasha yelled as she realized what he was doing. After continuing to struggle for a few moments, Tony grabbed a paring knife from the sink and thrust it into Steve's deltoid(shoulder muscle). Steve let go in shock and Tony flew backwards and hit his head on the sharp corner of the fridge, then squeezed himself into the small area between the fridge and the wall.
"What -" Steve started, only to be cut off by Bruce,
"What's going on here?" He was growling and turning green, dangerously close to hulking out.
"Bruce," Natasha turned to face him, "Tony needs you. You have to calm yourself down."
"I know. I know." Bruce barked and sighed softly, looking his trembling teammate. Steve just stood there, confusion and anger on his face, along with a bruise forming from Clint punching him as Natasha helped Bruce. When she was sure that Bruce would be able to handle himself, Natasha switched herself back to Steve,
"Thor, take Rogers away." Thor just nodded and immediately reacted, dragging Steve away with ease. When Thor and Steve were out of the room, all attention was turned to the 25 year old.
"Tony? Tony you need to calm down," Clint tried, approaching him slowly in a crouched stance, hands held up so he looked as harmless as possible. Regardless of his attempts, when he got within just a few feet of Tony, he scrambled backwards and flattened himself against the wall even more, "Okay. Okay, I'll back up."
"N-no... please," Tony whimpered, "I don't want to."
"Shh, Tony you're okay. It'll be alright." Bruce told him gently, approaching Tony in the same manner that Clint just had, but stopped to sit down when he was around 5 feet away. Then he turned to Clint, "Clint, grab something from the fridge. Something with a strong and recognizable sent. JARVIS play some AC/DC at a low volume."
"Of course, Dr. Banner," JARVIS responded, playing it immediately as Clint passed Bruce some of the blueberry, lemon pastries that Tony loved.
"Tony, I need you to pay attention," Bruce ordered, purposefully ignoring the whimper that came out of Tony's mouth, "Wherever you think you are, you're not there."
"No!"
"Tony, it's Bruce, okay? Pay attention to your surroundings. Listen to my voice and the AC/DC JARVIS is playing. Pay attention to what you smell, okay. You have to be in the tower because I'm the one who first made you try these." As he talked, Tony began to calm down and he inched forward and eventually was close enough to teach out and rub the small of Tony's back, which led to him lunging at Bruce and sobbing into his shoulder, " Hey. Hey, it's okay. I'm here." Then after a while he suggested they watch a movie and led Tony over to the couch, Clint and Natasha trailing behind them. Then they just sat there watching movie after movie, rotating choices, Tony practically in Bruce's lap. At some point Bruce had left to pick up the food they'd ordered and something about the action movie Clint had picked set something off in Tony and Natasha reached over to do the same thing Bruce had earlier. Luckily it calmed him back down and the rest of the night was quiet. Tony even admitted the obvious, that him and Bruce were dating. Then he repeated it for Thor with more confidence than before when he returned without Steve, who was staying in his old apartment indefinitely. Of course, Thor congratulated them (even though he already knew) and sat down to enjoy the night with them. After a while, Bruce leapt up in shock,
"I never inspected your head. Oh my god, I have to check you for head wounds maybe even a concussion."
"I'm fi- OW! Bruce!" Tony yelled accusingly when his boyfriend prodded at a lump on his head. Luckily, there was no blood, but Bruce still cleaned it with alcohol before putting ice on it. Tony passed the concussion test,
"I'm still worried. Let me know if you have any discomfort or symptoms."
"You worry too much Bruce."
