Earlier today, Fox unveiled its fall premiere schedule: Bones will premiere its sixth season on September 23.

Now that we know the when, we can also report on the what, as creator Hart Hanson has opened up to TV Guide about a couple major storylines for the fall.

First, he says, Deirdre Lovejoy will appear one final time as Heather "Gravedigger" Taffet. In this same episode, a new (likely male) villain will be introduced,  "someone much worse, who will dog us for the season."

He said this individual is "someone highly motivated to do great harm to our people - a personal vendetta. One of our characters will be a victim."

Hmmm... he didn't say main characters - and he didn't even say anyone would die.

Still, we're guessing this tease doesn't bode well for one of the squinterns.
