Hi. It's just me. Kate who owns plots only. Kate who likes readers and reviewers a lot.

She's tired, but her face is flushed from all sorts of things. It is late winter, and she's outside, and it's raining, so the cold is a factor, but she has also just got done having a blazing row with Ron.
She called him selfish and horrible and all sorts of things, because he didn't want her to fight, now that they were all tender words and holding hangs and nights by the fire doing nothing more than kissing. But he acts as if they've consummated their relationship, which they haven't, and he acts as if Hermione can't defend herself, which she can.
He's seen that in the past battle, and she's angry at him for telling her he doesn't want her to fight in the next one. She's angry at him because he loves her and just won't tell her. Telling her would make it easier on the both of them.

He pulls her inside the abandoned school at three in the morning. She is as white as a ghost and freezing. He takes her to the fire, and in a moment he thinks perhaps she's lost it, in which case everyone is going to lose it, hence pallor appears on his face as well.
He tells her then, in her stupor, as he finds some firewhiskey that he's gotten from who-knows-where and gives her some to warm her up. And maybe it's the fact that he's had a little himself that makes him say it, but when he does he means it.
Hermione answers Ron with the same words, and before he knows it, he's kissing her, or maybe she's kissing him, even though they both taste like firewhiskey.
When he pulls away later, he notices that her color is back, and feels that his is too by the hotness of his ears. But there's not much time for observing, because next thing, she's saying something about his ears turning red, and kissing him in all the wrong places, but he doesn't care, because it's Hermione, and he loves her.
