At that, she pauses to rest a hand on Hermione's shoulder, giving her a gentle squeeze. "Did nothing because of indifference, or because you froze? Somehow, I can't imagine the former ever happening with you."

She sighs, gathering her thoughts. "It might take a long time, but try to forgive yourself. You hold yourself to such a high standard, and most of the time that's awesome. But you can't change everything. Some lives can't be saved...and some can, but circumstances don't always allow it. It's not right, or fair. It fucking sucks. But it's going to keep happening, and if you can't accept that on some level, it'll break you. The only thing you can really do is to take action when you can, try to save those lives when you have a chance. And if you can't at that time, focus on the people who will need you later."
