Between a "Slumber Party" that finally killed the Wicked Witch, and a "Dog Dean Afternoon" that left the elder Winchester brother cleaning out his car, 'Supernatural' will finally get back to to the business of solving the angel problem in next week's "Heaven Can't Wait." We've got the first sneak peek of the hour, so what's the latest issue with getting those tricky tablets translated?

Kevin Tran (Osric Chau) is on the case once more, having been name-dropped in about every episode up to now, though translation grinds to a halt from the discovery of several dead languages, as evidenced in the latest clip. Elsewhere, Dean will pay a visit to his old friend Castiel, while Kevin and Sam are left to deal with the still-captive Crowley.

Says The CW of next Tuesday’s “Heaven Can’t Wait”:

CASTIEL GETS A JOB – Castiel (Misha Collins) gets a job at a Gas-N-Sip and actually starts to enjoy life as a human. A headline in the local newspaper about some disappearances in the area catches his eye, so he calls Dean (Jensen Ackles) to help him investigate the case. Dean knows he needs to keep Sam/Ezekiel (Jared Padaleck) away from Castiel, so he tells Sam that he and Kevin (guest star Osric Chau) need to stay and work with Crowley to decipher the tablet. Crowley agrees to help Sam and Kevin but in return he wants one phone call to hell.
