Since he's obviously alive. I highly doubt he's been recruited by Thanos (like Loki) but after seeing that episode of the Avengers Earth's Mightiest Heroes that explores the Winter Soldier I'm wondering if they'll adapt some of those ideas. It'd be especially interesting to see Fury's vendetta against the WS and use that explanation for losing his eye. Only if they choose to go that route of course. Do think this is likely or even possible?
