Oh, okay. This'll be a long one.
In character, Kristian regards Toby as one of his closest friends, as they have essentially gone through the same areas at the same time in their lives. He respects him for becoming a Regent, but overall he is a bit worried that Toby might have possibly gone insane. Even though they haven't seen each other in a while, Kristian holds a great deal of respect and gratitude towards his old Valiant pal.
Out of character, I think you've played Toby brilliantly, as he has evolved from that plank of wood I first saw him as to a really deep character with a very engaging story line. Whether it be ghost parents, silly siblings, or fierce debates between the two, I can always count on having fun whilst Toby is around. However... one request... age him a bit faster >_<. Kristian's like twice his age now.
That ain't happenin' brudda.
You'd literally have to tear off all his skin.
Don't do that please ;-;
