He keeps lashing out despite himself.] I told you everything you needed to know! Why would I ever want to get into what it's been like without you?! It's...
[Awful. He's never happy. He can't even grasp the concept of it even now that Sam and Nat have become his friends back there.] ... not what you needed to hear. I shouldn't have told you about it.
[Steve takes a deep breath and exhales shakily.] I remember. Believe me it's all that got me through the worst of it. You're still my best friend. I love you. I'd do anything for you.
[I'd let you do anything to me goes unsaid. He doesn't need to know every screwed up detail of it; that if Bucky was truly dead, he'd let whatever remained kill him. A part of him wanted it; death. He wanted to die.
Steve's eyes glisten as he remembers that final fight in the hellicarrier.] I'm sorry. This whole thing brought it all back. Everything that happened, everything I felt... I'm sorry I took it out on you. I didn't mean to.
