We speculated here about who's going to team up with Captain America. But the Winter Soldier can't be easily shortlisted here.

He is kind of lost. Literally and not only. He will return to Civil War after a soul searching phase of which we don't know if it's come to an end.

But will he come back at his own initiative? Will he be convinced by Cap? Will the Black Widow get under his skin and work her tricks on him in order to join the Avengers assembly?

What we know for sure is he was not seen at the end of Age of Ultron, next to Falcon, Scarlet Witch and Black Widow. So it's safe to assume he'll show up later. But will he tip the scale in favor of Steve Rogers?

In short, it's like this: Captain America has all the reasons to try to bring Bucky on his side. But the same can't be told about the Winter Soldier.

Or on Tony Stark's?

Indeed, the only argument fans usually bring to sustain the Winter Soldier won't play on Iron Man's side is the fact he killed Stark's parents.

Is this enough to rule out this possibility?
