In tonight’s third episode, Adrienne Palicki from Friday Night Lights joins the cast. She plays Vanessa Styles, a woman from Seth’s past, who warns Seth (D.J. Cotrona) about something she once discovered about Seth’s twitchy brother, Richie (Zane Hotz): namely, that he suffers from delusions of seeing things and hearing voices. Except, as this Robert Rodriguez expansion of his From Dusk Till Dawn movie already has made clear, he’s not delusional. And when he has a vision, it’s quite a vision indeed – of vampire queen Santanico Pandemonium, played in this series version by Eiza Gonzalez.
