with his lean 6'7 build, Jasper (Jazz) Dent is handsome and charming, and has a way with girls because of how familiar he's with the human brain. he's naturally manipulative even when he doesn't want to be, and because of his dad Billy (one of the worst serial killers ever) he knows exactly how to make anyone do anything. As a kid, Billy taught Jazz the methods and means by which Billy was able to kill without being caught. Jazz can naturally read people. he's sarcastic, smart, and hard to read.
