i agree the bucky and steve lack of reuion and goodbye bugged me a lot , it didnt make sense why we didnt get one.

the death of Tony & Nat hurt so much i didnt want them to die and i didnt see them being the ones to die i honestly thought Steve would .

Steve going back to Peggy made sense he never moved on from her it was always her , but i dont know how they interferes with the timeline seeing as peggy is very important to shield and the future ?
