Looking at the preview, I wonder if Michael feels snookered by Janine setting him up with her blood on his sleeve. He would rather be dead than go to prison and knows he wouldn't see Scarlett ever again if he ends up in jail. I wouldn't put it past him to turn the knife on himself. That would be the closest he would get to winning the battle with Janine. In his mind., if he can't have Scarlett, this would be the only way left for him to try and prevent Janine from having her - by setting her up for his 'murder'. And Janine has form for self-inflicted flesh wounds. And dead husbands.
