This is why I avoid actor interviews. The less I know about them and their opinions the better....but truly one person's view doesn't invalidate your interpretation. Even if he said yes, Steve and Bucky are totally in romantic love with each other, no romance like this would ever happen in a mainstream Disney movie, at least not in my lifetime. Or views will have shift much faster than they are.

EDIT: Sorry if my post was too negative. I think I'm deeply unhappy with that Steve/Bucky won't ever happen on screen and I think it makes me a little more bitter than anticipated. I had hoped views would have shifted by now to allow gay superheroes. I also think if Sebastian Stan came out and said something different and they didn't go there in the movie, people would have accused him of queer-baiting, maybe the studio told him to go with the "brothers" storyline to avoid conflict with fandom.
