Best Bucky Barnes moment/quote:

This quote is Bucky and Steve, but you need both parts. Especially since Bucky eventually says the other half.

"Don't do anything Stupid until I get back." "How can I? You're taking all the stupid with you." (Bucky and Steve)

This is just a quote that shows the strength of their friendship. They said it before Bucky left and now they are saying it before Steve leaves. Even after all Bucky went through he remembered Steve and it shows how strong they built their friendship in the beginning.
