A furious Mike tells Katherine he never loved her and thought only about Susan when they were together. Once he leaves, Katherine picks up a knife and, apparently, turns it on herself. [Agencies]

Nothing hurts like love: Katherine continues to head down the path to insanity, but this time, she tried to use Mike and Susan's young son, M.J., as a pawn. First, she fills the young boy's head with her woes and blames his mother. Then, she picks him up from a party without telling his parents. A furious Mike confronts her and ends up spitting out that he never loved her and thought of Susan every time he held or kissed Katherine. When he leaves, Katherine picks up a knife, calls for an ambulance, and then apparently cuts herself offscreen. Viewers hear a gasp and see the bloody knife, but not how serious the injury was. That was kind of a lot of blood on the blade, though.

And in another revelation about the Bolen family mystery, Angie sputters out to Nick that she was the one who killed a man. Who and why, of course, has yet to be revealed.
