I read an interesting Nerdist article about this today (because I've been furiously looking at ALL THE THINGS about the movie since I couldn't talk about it with anyone except The Bar and one lady at work but we kept getting shushed every time we brought up anything in our whispering) that talked about how Cap has been a man out of time and he set everything right before finally doing this one little jaunt. My thought process has been since reading it that, in a way, he sets things right with getting back into his time line. He just had to keep away when all the good bits were happening that Original Cap was involved in.

I also really liked getting to see that the Avengers had help in the Battle of New York when we see The Ancient One doing their bit to help out. It makes me think that maybe this Old Cap was there, doing a bit to help out when he could, watching out for his friends.

But Old Cap would have known about Bucky the whole time. How could he have set on that bit of information for this long? But there's also a part of me that thinks that Bucky wasn't surprised by Old Cap being there so maybe Old Cap insinuated himself into the Bucky timeline.

Ack. I'm rambling!
