He would be lying if he said he wasn't worried and part of him just wanted to say to hell with Tony's plans. He probably would have, if they weren't stuck in this unusual city with no one else to trust with this. But he just had to trust Bucky, it wasn't like going outside right now was a big deal.

Although, people usually walked around with both arms. That wasn't the point though. "Be careful out there."
