hey yall sam’s witty and sarcastic comments are definately a trait of his but its not his only personality trait,,,, sam has always openly shown as friendly and caring
most of yall only care about mcu so lets review:
sam right off the bat introduces himself to steve rogers. not captain america steve rogers, steve rogers the soldier. the man that fought for his country, showing understanding of the overbearing difference between life in war and life in civilazation. he tells us about how hes served, not once, but twice, as a pararescue. rescuing people.
he’s shown talking in the va, telling a group that the worst is behind, even if bad things are with them now, its going to get better. that together theyll figure it out and handle it all. the way he stands in front of the group, you can just see that he is listening to every word.
he meets steve again, talks his own loss, his own feelings of the loss (riley) and that he too, lost purpose at that point.
he meets steve, steve whose never been one to follow orders, steve who finds himself in a place with too many serects for his liking. steve who doesnt know what he would do without this kind of work though. sam tells him, he can do whatever he wants to do. he fully believes he can too
then steve shows up on his backdoor step with nat, covered in dirt and on the run and immediately lets them in, feeds them and wants to help out. he wants to get back in the action and what better way to do it then with captain america
by the drop of a hat sam signs up to start helping people again. he continues to help and help steve with bucky, the avengers and so much more.
dont even get me started on him in the comics
yeah sam not moving his seat up for bucky in civil war is funny and all, but theres so much more depth to him then just “comic relief”
