Re: Captain America: The Winter Soldier pre-release thread
It's been hinted that Bucky survived that fall into the frozen river because of the experiments Arnim Zola performed on him.
Yes, the outcome of those experiments was a prominent dangling thread. Also, according to formula, when a character "dies" like that, he generally survives, because in some way all is not what it seems.
