I love how the show builds stories around urban legends or, in next week's case, actual historical people. After reading the pre-vue for the show, I had to look up online just to see if the guy named as "America's 1st serial killer" was real.
Okay, anyone else getting sort of a "half sister" vibe from Joanne, I think is her name? I've been wondering ever since she and her mother appeared, if that girl is John's daughter. That, and the fact that Dean isn't as all over her as he usually is with pretty girls, leads me to think she's going to turn out to be their sister.
I hope John somehow gets brought back. If Buffy's rotting corpse can be reanimated without making Buffy a murderous zombie, there's got to be a way for John to come back.
