“There is definitely some [sexual] energy between the two of them,” executive producer Alan Ball tells EW. “It’s not like either one of them is looking for romance, but they’re thrown into several intense situations [and] it’s hard not to bond on a deeper level.

And of course, this being True Blood, he’s already shot his first naked scene. Hello, werewolves when they shift — no clothes!”
