In "The Girl With the Dungeons and Dragons Tattoo," Felicia Day plays Charlie, a brilliant but unsuspecting hacker that Dick Roman enlists to crack Frank's hard drive. Sam and Dean, of course, try to stop her. As shown in these first look photos, things don't quite go as expected for our boys. The episode airs on April 27.
