Hi there!
I'm another one of those folks who didn't expect to love this pairing as much as I do. I'm a huge Tony/Pepper shipper and thought they'd be my only ship in the movie, since I knew Natalie Portman wouldn't be in it and there wouldn't be any Thor/Jane, but then Black Widow and Hawkeye had their scenes together( and Budapest ) and then I saw the Tumblr graphics and vids on You Tube, and I was hooked!
