So Bruce Banner lost:
his best science buddy, the guy who housed him while he was coming to closer terms w/ the hulk
his semi girlfriend, or at least the girl he loved and trusted enough to know he had to walk away from her
And the guy who helped him through the roughest, and darkest patch of his life, the guy who helped him a lot more with his relationship and the hulk, the guy who saved him from himself. Thor straight up leaves at the end of the film, leaving Bruce all by himself.
I know everything sucks, but Bruce really didnt get a happy ending. Steve lived out his days, and Clint has his family and retirement now, but Bruce??He's all by himself on earth, w/ no familiar friends. Yes, he's a canonically a celebrity, but what a lonely life it must be to be famous and have no close friends to trust.
