RUBY: "Tom? Okay, look at me. Look at me. Now...this is my SCALPEL...here, I'm putting it down over here...and now I'm walking away from it, over here. I'm unarmed now...so...please...put the caneshovel down...and...lets just talk about this, okay?"

Drop the scalpel, explain that they need to talk it out.
