Mari says:
 I FEEL GOOD RIGHT NOW
 because I was right
 which means Magpie's body is his lil bro
 and the weak heart came from the bullet wound?!
 YEAH because he was shot at and "died"
 so maybe BB fixed his heart
 but needed the soul
 but then he thought, this boy won't last long, and got a hold of Paytridge's
 body*
 so he got magpie to go into the magpie body
 and fakeridge is... well...
 I mean, think about it. "You're not my type", Bri is a younger woman...
 'cause in the story, Little Bro loved an older woman
 who had a kid who was old enough to buy a gun and kill him dead
 so yeah, he likes older women
 and Bri's young compared to them
