Hermione stares at him in shock. Yes? She knows he's a good liar, but she's certain he's not lying now; he would gain nothing from it, and he hasn't lied to her yet, not really. He swallows again, throat clicking dryly, and she believes him. And...is it wrong that she enjoys the sight of fear in his eyes as he looks at her? She shifts her grip on his wand, getting a sense for it. It's warm and feels friendly – pliable and cooperative, and she thinks that it shouldn't work too terribly in her hands. She tries a lumos and it sputters and then flares before collapsing entirely, so not a reliable wand, but she thinks it will be serviceable enough for her purposes.
