A couple Ghost Whisperer casting notes to pass along:

* Margaret Cho will reprise her role as a teacher of the occult for two more episodes. Says Producer Ian Sander: “She’s going to help solve some crimes.”
* The Shield actress Catherine Dent will also come aboard a future installment, portraying a drunken ghost named Laura. “It was really fun playing a drunk because I could show up to work looking like crap,” said Dent.
