We are geeking out over this announcement: Whedonverse veteran Felicia Day will be guest starring in an upcoming episode of Supernatural!

TV Guide reveals that Felicia Day will guest star in the April 27 episode ‘The Girl With the Dungeons and Dragons Tattoo’ as a hacker. Showrunner Sera Gamble teases:

Felicia plays a girl named Charlie who is sort of a lowly tech working in one of Dick Roman’s companies. She’s an amateur computer hacker and unwittingly gets wrapped up in Sam and Dean’s problems. It’s a classic story of an everyday girl who does not want to be in a whistleblower position.

We are so stoked to see her on Supernatural! Felicia is best known for her roles on Dollhouse, Buffy the Vampire Slayer and in the web series Doctor Horrible’s Sing-Along Blog and The Guild.
