Of course, Tonks noticed him the moment he came in. Nymphadora was paranoid enough these days not to miss anything, really. Friendly or foe walking in that tavern door and she was going to make an evaluation before she went back to her tea. Of course, when the door opened, he was the last figure she expected to see. Part of her hoped maybe one of the Weasleys or at least a familiar order face, but not that familiar one.
Still, she wasn't a wilting, blushing flower. She could have looked down and away, she could have hidden her eyes and pretended he didn't exist. But that wasn't very Nymphadora Tonks and it certainly wasn't Nymphadora Lupin. So, as he stared at her for full second, she stared right back. Quite, harsh, daring him to come over. Daring him to confront the issues between them.
For her part, she looked almost as rough and ragged as he did, and that was a rarity. Even if she wasn't feeling well, she normally had a brightness and youth about her which few could match. Her pink hair was always attributing to such a quality. But tonight her hair was it's true mousy brown. Dark circles rested beneath her bloodshot eyes and her face looked more ashen than blushing and well. She still didn't look away. She waited for his response to her gaze.
