I'm really hoping this is one of those deals where the writers knew there was a good chance they wouldn't be back for a second season so they wrote this as both a season finale and a series finale. Honestly, I'm never particularly satisfied with those since they don't give the sense of closure they should, but it's probably the best we can hope for. I'm just concerned it's going to end with a huge cliffhanger that's never going to get resolved.
