These scenes…I really wish they’d been left in.  You truly get the sense of how displaced Steve feels by what has happened to him. 

His hands on the train, his body language, he looks so alone and lost. These scenes never should have been cut.   This is the first we’re really seeing him out of the ice; they’re necessary to his character development.  It also serves as a far better introduction to Steve Rogers than just the punching bag scene since much of the audience hadn’t seen CA: TFA.
