The spear don't have to looks dangerous, Xavier, it just have power when the Fencer knows to work with it.
And to your quesions:
1.) Fencers everytimes looks sad or serious, their life is a whole fight. Alos' was one of the biggest Fencers there and i think you know what he had to do to protect a lot of things, to heal trees, clean water and make the air fresh.
2.) When Alector is praying to his father, will his body totally different. You can see on the pic, he has a darker skin there. The more he pry to his father, the more power he get. Yep...they are wings on his back.
3.) Xail is one of the worse enemies of Alector, and what would you do when he tries to kill you? think as fencer the same thing like Alector: kills him before! Xail is disemboweled there.
Ok....
