Kayle Fled the Battle
Reading the short bios of both and I had to scratch my head over this. She watches her father die in Morgana's arms and retreats to Targon. There's no mention of her being unable to deal with Morgana. Was Morgana's question about their father being wrong in taking them away truly that incapacitating?
Quite a bit of talk on the boards about being unable to relate with Kayle's character, but I have to disagree. We all have issues where we become uncertain about our course of action.
Sure, Morgana is rather straight forward by comparison. She's daddy's little girl, whom is angry with an errant mother that chose duty over family. Kayle idolizes her mother, which is a difficult thing to deal with as a single parent. And there's no way you would ever tear that away from her, when that's all she has of her mother. Well... short of hating her mother and then you would just end up the bad guy. Am I getting to real at this point?
Anyways, I feel much worse about how Kayle ends up than Morgana. What does Kayle find at Targon? I think it quite unlikely for her to find her mother, so... that could be harsh. Clearly she has been clinging to that. I think I would conclude Kayle is much more "broken" than Morgana is in regards to personality. Rather tragic.
