Tony had many bad habits. Drinking, over working himself, gambling at times. There always has to be something to keep his mind busy. If he wasn't working out a problem then his thoughts took over. So Tony spent most of his waking time in the lab.
Tony's bad habits started to slow down when he was working in the Avengers. When he met Bruce. Bruce was the cause of the end of Tony's drinking problem. He stopped overworking so much all because Bruce asked him to take a break. He didn't gamble with his life or any other way cause Bruce didn't like it. Tony would do anything for his Brucie.
Tony was in the lab again one night. It has been raining and Tony didn't like the rain. It reminded him of the water dripping in that cave way back when he was being held hostage. Not the best of times in Tony's life, but it could always be worse. Tony had a opened bottle of beer sitting on his desk as well as music playing loud enough to drown out the rain and his thoughts. Tony was glad he had the lab soundproofed, otherwise the whole tower would be hearing his music. Tony really didn't want to sit and listen to one of Captain America's long and boring speeches.
Tony was half way done with his second bottle and almost completed a new project, when Bruce walked in. He had on a pair of sleep pants and one of Tony's many over sized hoodies. The sleeves were over his hands, turning them into paws. Bruce looked around the lab and spotted his partner. Bruce sighed softly to himself and walked over. Tony didn't notice him, to busy in his own world. Bruce took the bottle away and told Jarvis to stop the music. Jarvis, the traitor, did as was asked, much to Tony's disappointment. Tony whined and looked at his boyfriend. Bruce just shook his head and pointed to the door. Tony got up and followed him out, only now realizing the rain had stopped and just how tired he really was. They went to bed with Tony's head laying on Bruce's chest, over his heart.
Tony knew old habits die hard. It's probably why he's sitting on top of the tower in the Iron Man suit, drinking. Bruce got hurt on a mission. It scared Tony. He looked out at the view and reflected. He had a found family that actually cared for each other. He had an amazing boyfriend and best friend. He wasn't dying, this time. His life is pretty good. He was scared cause he came close to loosing the love of his life. He had this nagging thought in the back of his head telling him everyone was gonna leave him at some point. His parents died, mentor betrayed him and died, his friend who saved his life in a cave died, Bruce almost died. Everyone he has ever cared for has left him. Pepper only comes around when she needs him to sign something or to make sure he isn't dead. Tony sighed to himself and finished his drink.
Tony let the armor go back to its case and headed to the medical bay. He walked in and went over to Bruce's bed. Bruce smiled up at him, sleepy and hurting. Tony smiled back softly and say beside him. They held each other's hands and Bruce lifted his free hand to play with Tony's hair. Tony laid his head on the bed. It was a close call, but Bruce was alive. He was gonna be ok. With time Tony will kick these bad habits, but for now they help ground him along with his favorite habit. Bruce is a good habit though.
