If anyone doubts the writing sharply deteriorated after Victoria left, then they should watch this scene with crazy Katherine. First of all, why would Katherine even approach Bobby after the previous scene showed her relishing Pam's plight, and we're led to believe she is about to hatch a devious plot regarding Pam. Did she think Bobby would welcome her with open arms or better yet, let her walk off scot-free? Oh wait, that's exactly what Bobby did. He didn't call for security or yell for help after first spotting Katherine, or even after she says she is going to turn herself in. I know the plot required Katherine to leave the hospital, so there would be a question later as to how Pam disappeared from the hospital, but there are no words to describe Bobby's stupidity here. The writers should have had Bobby catch or see Katherine exiting Pam's room, and Katherine run off before he could call for help without the inane dialogue.
