When Torchwood hits the airwaves for its fourth season, geek goddess Jane Espenson will be penning several episodes. Espenson, who has written classic episodes of Buffy the Vampire Slayer, Battlestar Galactica, Caprica, Dollhouse and numerous other sci-fi series brings a fan base all her own to a season she says will be intense. “I’m thrilled to say I was invited,” Espenson told Blastr.com. “My agent told me about it very casually; I was already busy at the time, and he thought I’d want to decline, but I jumped in fast to say I absolutely wanted to participate.”
