Hermione frowned and looked down at her lap. She couldn't tell them that Dumbledore was retiring to help them, but what she could tell them was so much worse.
"He's staying on at the school. you know. Living there, to help with the transition. But... really he retired so that he could help Harry." And she couldn't hide the next part, because when it came she didn't want it to be a shock or betrayal to everyone. She looked back up at Neville with a sigh, "I think he's dying. I know he's sick. It's something slow, but not something that be helped."
