Well Loki is the trickster and Darcy did taser Thor in his first movie. "What? He was freaking me out!"

I was rather fond of a fanfic that shipper Darcy with Cap because, like Peg, she's a busty brunette.Unfortunately the author never finished it

Which is a pity because it was a very good story.
It's called Skipping, look for it at the fanfiction site. The author goes by missmissa85
