I don't really want to spoil here, but the dude is a psycho. He doesn't have any empathy, and Chase was a kind and sensitive boy, which unfortunately he couldn't understand (along with the rest of their family). So he traumatised him a lot to try and make Chase like them, to "help" him, and he just doesn’t understand how wrong it was.
Who is this chase again?? How is he related to Keith?? Or does this couple introduce in kiss me liar? I can only remember Josh and his children. Can't remember seeing chase in kiss me liar. (●'◡'●)ノ
