"Calm down," Draco said lowly, "Remember - it's like I said. The past is not the future anymore - we don’t know what is and isn’t going to happen, and that’s okay. It’s how we’ve lived every day of our lives, except for the last few months, after all," Harry nodded, trying to calm himself down, "and if Nagini is dead, then Mister Weasley can’t be attacked by her, can he?" Harry nodded again, less shakily, "and even if she wasn’t, any number of things could have happened that meant Mister Weasley wasn’t anywhere near her this time round, right?" Again, a small nod, now calmer, "And I definitely think you should maintain your occlumency shields - no, don’t look at me like that, I know that look on your face - you can’t lower them just to spy on the Dark Lord. Imagine if he managed to spy back? How disastrous that would be?"
