I understand why some would be pissed if they jerk us around for two weeks and Glen turns up okay (ironic that they had Lindelof on the show because that was the reason I stopped watching LOST after the first season: manipulation), buuuuut... all I can say is if there was some way that Hershel could have made it out alive, I would've been the happiest fan on the planet.
Deus ex machina or not, I don't want Glen to be dead. Not Glen.
