As he watched Bucky's smile fade and turn serious, Peter's own smile faded as well to match it. It was rare for Bucky to be this open to him. Peter wanted to show that he took it seriously. The mention of Hydra only strengthened that feeling. It was a sobering thought. Even though they had been talking about it, hearing Bucky refer to himself as an assassin and killer made it more real. It was sometimes difficult for Peter to see Bucky as a killer. Sure, he could be really intimidating and he was really strong, but Peter saw him muching on popcorn during movie nights and he had seen him in pjs. It was difficult to see that version of Bucky and see an assassin. "I think you're a good guy. You've had bad things happen to you, but that doesn't make you a bad person or anything. You're doing good things."<br/><br/>Peter chuckled. "It wouldn't be the first time I accidentally blow myself up. It's gotten better since I got access to the Tower and the lab, but back when I was on my own and making my web formula I had a few accidents." He probably would still have these accidents if Tony didn't look over his changes before he started mixing things. "Besides, even if we build a prototype and it blows up there shouldn't be anything in it that can hurt us. I'm not making it to injure, just to get people stuck in my webs."<br/><br/>Peter grinned. "I'm sure mr Wilson would appreciate that." It was touching to learn he was on Bucky's list of important people. He had a feeling it was a short list, so to know he made the cut felt good. "For what it's worth, you're on my list too. You're pretty cool, mr Bucky. Kinda like the reliable and cool uncle you go to instead of your dad because he'll kick your ass."
