Höstpeppen!

Jewel Staite från Firefly kommer att vara med i Supernatural i höst!! Eeeep!

Från comic-con:

In the actual Supernatural panel in Hall H, they showed a clip from the first episode filmed, which Ackles directed — in which we see a flashback to Sam's childhood including his first ever kiss. And the words "Amy Pond" are mentioned. And it's framed by a scene of Sam and that girl as adults — the girl being played by Firefly's Jewel Staite!
