Yeah that's definitely a possibility.

Whose hands do you reckon it was around Sookie's throat when she was asleep?

Sam was also wearing a blue shirt but the cuffs were different.

They really didn't give anything away in this episode which leads me to assume they have already been guaranteed a 2 or more series and so are settling into some Lost style watertreading for a few eps.

I think it's going to be a few weeks of character development and little real action now

I'm still sure Sam is a shapeshifter or werewolf but I don't think we will be hearing anything more along those lines for another month or so now...........
