I can understand them not wanting to kill the character off, but it's Bobby's reaction, and the way they wrote Pam out that has just never worked for me. It wasn't like Pam had decided she just didn't want to be married anymore; heck, they just found out she might be able to get pregnant. Things were good, and then she was in a terrible accident, that apparently disfigured her so badly that she was traumatized to the point of running away... Was this a rational decision on her part? No, but she wasn't in her right mind, and Bobby just receiving the letter, being mad at her, and compartmentalizing, writing her off.. huh? Obviously the powers that be wanted us to just forget about Pam(for now), and for Bobby to be justified to start getting romantically involved again. I agree that they underestimated the importance of Pam, but while I would have liked for them to have a little more time together, I could have handled her leaving, had the whole plot been done in a believable way.
