Felicia Day's quirky tech genius will be a little out of sorts during "There's No Place Like Home," and it will only be by happenstance that Sam (Jared Padalecki) and Dean (Jensen Ackles) come across their suddenly dark friend.

"The last we saw Felicia, she was off to Oz. So clearly something has happened to bring her back to the Earth realm and Sam and Dean are both flabbergasted because we thought she was off to Oz, happily ever after, never to see her again," Padalecki explained to Buddy TV. "We soon find out that something has happened in Oz that she is trying to solve on her own. By happenstance, we run across each other and we're able to help her and offer her assistance as she has offered us in the past."
