Video: Sam Witwer Talks 'Being Human' Season 4

At Comic Con, we snagged Sam Witwer to talk about Being Human. In the upcoming fourth season, Sam's vampire Aidan will have to deal with his wife, whom he hasn't seen in 200 years. ("Have I been cheating on her this whole time?") Sam also tells us about the changes Aidan will go through, and hints at some familiar faces we may see return.

Being Human will return to Syfy this January.
