Post Credit Scene
"I'm taking off for a bit." Steve said to him as he walked into the lab. Tony looked up quickly at the sudden entrance of the Super Soldier. He knew where Steve was going. Natasha had explained to him that Steve knew, and she had told him to tell Tony about his long lost friend now super assassin. About what he did. She had only told him so he would have the luxury of shielding his true reaction from Steve. He took a deep breath steeling himself for the news the soldier was probably here to tell him.
"Yeah? Where you headed? Popsicle convention?" Tony asked, turning to look at the man, hoping none of his apprehension was showing on his face. Steve let out a stiff chuckle at his joke before continuing.
"No. I-uh...well Bucky's alive. I gotta go find him." Steve said, voice tight. Tony nodded.
"Wow, what are the chances you're best buddy lived this long huh?" Tony said, pretending he didn't know anything, just like Natasha had instructed him to. He could see as Steve wrestled with what to say next, a conflicted look on his face. Finally it turned into one of resignation, and Tony knew this was it.
"Yeah. Well, I just wanted to let you know. I'll check in when I can." Steve said, and then hurried out of the lab. Tony felt the sting of betrayal settle deep inside him. He stared at the retreating figure in disbelief.
Steve. The man he thought of as one of his best friends...was going to keep this from him. He didn't know how long he sat there staring at the doors, but suddenly his wife was standing in his field of vision.
"Tony?" she asked softly, concern lacing her voice.
"He didn't tell me." he felt himself say. He heard Natasha let out a frustrated noise, but he was too focused on the uncomfortable feeling filling his gut.
"He didn't tell me."
