I didn't know you were a "Ghost Whisperer" fan. I once read an interview with David Conrad where he said the producers told him, when he was first cast, that Jim probably wasn't going to survive the first season. I guess once the show got going they liked him and kept pushing back his "death," only to finally kill him off (and bring him back) in the fourth season. Not sure why they did that at all, though, seeing as how things have since gotten back to normal and it's like he never died in the first place.
