True-Blood.net & True Blood the series were invited back to PaleyFest just 2 years after their first appearance, an honor we believe has never before been bestowed. Last night, in front of a sold-out venue, sixteen cast members and “keeper of secrets” Alan Ball answered questions about their characters’ growth and teased more about what’s coming up in season 4. (We’ll save the spoilers for the end in case you’re avoiding them.) The event opened with a “relevant highlight” selected from the Paley Center vault: a scene from the pilot episode of Buffy the Vampire Slayer. Good choice! Following a brief introduction by a Paley Center official, Alan Ball took the stage to introduce a compilation reel from True Blood seasons 1-3, promising a “special bonus scene from season 4″ at the end. We expected it to be the glee-inducing clip of Eric posted online earlier in the evening, but no, we were treated to yet another fresh clip, which will be discussed under the Spoilers header below.
