Castle : Well, if it’s revenge you wanted, Why not just kill me?
3XK : Where’s the fun in that? Oh, no, no, it’s more fun to destroy you. Why do you think I let you live that night in the motel? People think it’s killing that I like . But murder’s just an act.

Knowing that I’m gonna take it all away from you… That’s what I like. “
