Hermione was so, so glad to be back at Grimmauld place – which was certainly something she'd never expected to feel. Standing in the doorway appreciating that fact was a bad idea, however, as she was almost immediately shoved unceremoniously out of the way by Harry.
"God, Hermione, I can't believe I'm back here, after everything." She looked at him closely, seeing him clearly for the first time since the battle had broken out just a few hours before. He was covered in small cuts, blood and grime, twigs and stone dust in his hair. She couldn't imagine she looked any better. God, her hair was going to be an absolute nightmare. "I know, Harry. But we're back, and V-Voldemort is gone, and.. And nobody else is going to leave us, now." She replied, almost unable to speak through her suddenly tight throat. "I'm going to bed now, I think. I'm sorry, I just.. I really can't do this right now. I'll see you in a few hours." He looked at her, barely seeing her through the muddle of thoughts written so clearly on his broken-hearted face, and she couldn't stand it any more, seeing Harry's face without Ron standing beside and a little bit behind, poking his head out to grin, or stick his tongue out, or shake his red hair out of his eyes. So she did something she thought she'd never, ever do – she ran from Harry. From her best remaining friend. From the reminder of all she'd sacrificed in the truly awful war.
She collapsed on the bed, not even taking the time to kick off her shoes, and was unconscious almost before Harry had registered her fleeing.
