Ghost Whisperer

Anyone else a fan? I'm really excited about tonight's episode, which looks like it's returning to the Underworld plotline, and I was wondering if anyone has any theories where that's all going.
I admit, I watch it on Friday nights with the wife. Some of the story lines are a bit lite for my liking but lately it seems to be getting more into darker stories and less about simply watching JLH on the screen. No theories about the Underworld line... I think I've missed too many episodes this season to fully follow along. :(
