Here, have a fanart (click for big):
I like to think that Lockon is the most stable of the meisters, because he has someone to fight for, someone to protect. (Well, you could argue that Allelujah has Hallelujah, but it's not really the same.) Not that Lockon is a complete picture of mental stability himself, but he his better at pretending it than the others.
Hmm...I wish we knew what Lyle (I'm assuming that's his name, and what kind of a strange name is that anyway?) is like. I get the feeling that he wouldn't be pleased with Lockon if he knew what he was doing, and I don't think an 'I was doing it all for you' would cut it.
In non Lockon news; I'm going to see my parents for Easter, so I'll see you all in a week or so, hopefully with a new page of Clematis, and a belly full of chocolate.
