Odd little episode has a fellow professor of Jay Mohr's not showing up in photos, but it turns out this is part of a haunting following this professor around. The real dead person is a student with whom she was having an affair. And his old girlfriend is apparently dead as well, having drowned within an hour of his death. Or is she? Melinda goes in search of the truth. Meanwhile, her spouse contemplates going to med school. And her shop asssistant gets quite the hairdo makeover. Whew! Jay Mohr is on hand for a bit of comic relief. Just coincedentally, the gal playing the supposedly dead girlfriend played House's most recent patient, the one who saw apparitions last week. Azura Skye. Interesting actress.
