GHOST WHISPERER had a frightening episode, but I'm not quite sure why the guy who can also see spirits disappears with them in her visions. He's not dead, so if he's there, he should be flesh and blood.
There has been a lot of speculation about the person close to Melinda who may die, and to me, it's obvious it's going to be Jay Mohr's character. That's just a guess, mind you. I have read no spoilers or inside information, but they've tried to keep the spotlight on David Conrad and Camryn Manheim, so common snese would dictate they're trying to steer us away from the one who's really going to die.
