User blog comment:LokiIsAwesome/Why Alvarr is such a big of a character/@comment-5102537-20120719151858/@comment-5139779-20120720055546

I believe he wasn't one-dimensional because he was not a steryotypical liar and schemer. He had a heart too. He loved Morgana and Mordred because he told them to flee for their own sake. He was also very unique because many villain's of the episode died or redeemed at the end of the episode. The only other ones I can think of are Odin and the Dochraid. He also strongly despised Uther as he was responsible for his parents' death. And you can imagine that he'd be super eager for a rematch after the battle they had in Series 2.

I will accept that you don't need him back if you answer this one question,

Why Alvarr left alive at the end of the episode he appeared in?
