When Bene says that, something in Colin snaps. He picks up a pillow and starts beating the floor savagely with it, as if it's a truncheon and the floor is Leander's face. When that proves not-quite-satisfying, he places fingernails in the seam and tries to rip it open. Fortunately, thread isn't in the business of just snapping. Unfortunately, he drops the pillow and claws at the one thing he knows will respond the way he wants it to--his own face.
