Rachel Miner will reprise her role as the demon Meg Masters, who was last seen in Episode 6.10: Caged Heat. In that episode, the demon teamed up with Sam (Jared Padalecki), Dean (Jensen Ackles), and Castiel (Misha Collins) to take down Crowley (Mark Sheppard).
While no story details were given surrounding Rachel Miner's return, we reported in December that Misha Collins is returning as Castiel in the 17th episode of Season 7. Since there was a romantic connection between Meg and Castiel in Episode 6.10: Caged Heat, it seems possible that they may reunite this season as well for more demon-on-angel lip-locking magic.
Supernatural, which stars Jared Padalecki, Jensen Ackles as the demon-hunting Winchester brothers, returns Friday, February 3 at 9 PM ET, with the first new episode in three weeks, Episode 7.13: The Slice Girls.
