Gwen is not going to die -- she's in the next two episodes. Also I recall Guinevere's role in Excalibur (the movie), after having an affair with Sir Lancelot she committed herself to a nunnery. At the time King Arthur found them together he thrust the sword between them while they were sleeping. Thereafter, when it was time for Arthur to go to battle he went to Guinevere to get the sword. She prepared him for war, and went to him at the time of his death.

Like I said, Gwen will be there by Arthur side, probably at the very end.
