"I am aware it is no easy task. Seek counsel with Professor Snape and Miss Granger and include them in this decision, because yes, it is ultimately your final choice. I would never force you to do it. I have informed you of the benefits of your actions in this matter, but if you refuse you shall bear no further ill will on my account. And in such circumstances, Professor Snape knows what to do. You have time to contemplate the situation and the changes in your relationship with Miss Granger after the events of tonight."
