Dollhouse‘s Amy Acker finally gets to play dress up in the fairy tale television series Grimm. In last week’s episode “Tarantella,” Acker stars as Lena, a man eating spider woman called a Spinnetod. She conceals her identity with a variety of costumes and wigs, including a very sexy blonde. Detective Nick Burkhardt manages to track her down when one of Lena’s victims bites off her finger. When he asks to see her hand, it’s already grown back. She asks, “Any other body parts you want to see?” Fortunately for Nick, he’s a happily married man and doesn’t fall into this spider’s web.
