#(endgame)

with all the doomsday chat going on i think it's important to remember that sam was actually the one steve didn't tell about his plan/say goodbye to before he went back in time, not bucky. when steve didn't come back immediately, sam was worried and confused and yelling at bruce to get him back. bucky, on the other hand, had told steve he was gonna miss him and in return steve said don't do anything stupid until i get back, which is what they said the first time they knew they were gonna be apart for a while, and when steve doesn't come back, bucky does not look worried or confused. he looks sad, sure, but he knew and accepted it. so if anyone here was betrayed by definition, i think it's sam.
