I'm hoping it's all rumors or misdirection. But a lot of the time these rumors end up being true...and remember, originally it was scripted that Steve and Nat would end up in bed together. I just don't get why they would let her wear that necklace then, Marvel is on top of their shit, you'd think they would have been like "oh well in Ultron Widow and Hulk hook up so don't confuse the poor fangirls."
