Have you seen this man — err, vampire? HBO has released a new one sheet for the forthcoming third season of “True Blood” tat features a blood bottle with a missing person sticker on it. “Missing. Have You See This Man? William Thomas Compton. etc etc.” Those of you keeping up with the franchise know that Compton was kidnapped to end the second season setting up the whodunit plot for season three. Any guesses? “True Blood” returns on June 13th. Guess we’ll find out soon enough.
