That is not a “don’t give a shit” face that Vision is wearing. That, if anything, is a “all who have wronged me will pay dearly” face.
I don’t remember Vision having any romantic involvement with Sam it or Jane, nor that he had any issues with them, so it’s a bit baffling.
Anyway, I wouldn’t have had any problems with this going somewhere but I’m pretty sure that was about it? It seemed to be more of a middle finger to a certain subset of fans, which I’m not opposed to per se.
