Kevin (guest star Osric Chau) talks Sam (Jared Padalecki) and Dean (Jensen Ackles) into checking in on his mother (guest star Lauren Tom).  When they arrive, they see that Crowley (guest star Mark Sheppard) has surrounded her with demons so they rescue her and take her along on their quest to find the tablet.  However, they soon discover Kevin wasn’t kidding when he said his mother was a strong-willed woman after she tries to take on Crowley.
