The reason for Watson's question was clear and completely understandable. Hannibal was well aware of how unethical his presence would be, given his close relationship with Abigail. Moreover, Hannibal had taken it upon himself to prep in the OR without consulting Cuddy or Watson first, and that was rude. He would apologise. "Knowing that Abigail is hurt is difficult to accept, yes. Nonetheless I have accepted it and what I imagine is likely far more gruesome than what is to come. If I believed that I was not capable of helping her in here then I would not be in here." Hannibal addressed both Cuddy and Watson knowing they would both be on the same trail of thought. "However, I do understand that my emotional state my change on her arrival and if that will deter me in any way then, I assure you, I will not begin the surgery."
