Well, Ward was Hydra. I didn't know him but the affiliation was familiar and I wanted familiar. I didn't get really close with the others until that first Steve disappeared. I'm a former Hydra stray, Clint just likes to take in strays. Jemma's a sweetheart. I don't have much of a life. I make terrible life choices involving face twins and pirate bars.
He's... whatever. I get that he's not either of those other Steves and I get that it's not like that. Hell. I got rid of everything that belonged to the others because holding on to that was stupid and would only cause confusion in the long run. I've coped separately from him. I don't expect him to ask about me anymore.
He makes his own decisions. I don't feel one way or another about his decisions. I planned on sticking you and Grant in the middle anyway. So I don't see a problem in everyone going to this movie.
