Bradley Stixle wasn't always the timid,  friendly  kid we know

[And still isnt]

But in his past,  he was a  phsycotic.... Animal

It only disgraced his own kind

He was blood thirsty,  mistreated,  deadly  kid when he killed his father.. He loved it too
He had to be chained down,  and muzzled up to be sent with his uncle and cousin... 
(His uncle is the one with the blue arms)

Taking his gem away seemed to make things worse,  because to punish him,  they threw it against things,  making a small crack..
Soon to affect his future

But.. When he meets a girl.. Who is different.. Can she tame him?
