User blog comment:Emily Windsnap/Why Elyan's death wasn't sad at all..../@comment-5674726-20121115001902

I think that Elyan was the only one they could have killed off. Had it been one of the others, their death would have been a case of Arthur losing a friend and knight rather than having a huge impact on Guinevere. Elyan was the only one with a stronger connection to Guinevere than to Arthur.
