Myron would have answered her question about the impact of sunlight honestly, that even indoors if enough windows were open to let the light in, that could be problematic. But then she went on to get all worked up because he had dared question whether she was paying attention in response to her assumption that he cared more about revenge than making sure his missing friend was all right. He knew he'd been prickly about it, but Merry was still gone, and she'd taken it upon herself to tell him what to do, like he was a child, for one, or like he didn't actually care about Merry, for two. Both of which he thought he'd been pretty clear were bloody wrong.
He felt his temper flare a little, but he kept himself in check as he unfolded himself and stood up slowly off of the couch, his eyes on hers. "Can dish it out but you can't take it, hm? How boring."
At that, he headed for the door. He wasn't going home and didn't have anywhere to floo. He'd fly around again even if it was useless and he knew he probably wasn't going to find out anything about Merry. Maybe he'd find someone else to snack on, because he was still hungry. All this had done was whet his appetite, and now he was bristling with sexual frustration in addition to the cloud of worry over Merry that he couldn't shake.
Fat lot of help Lorelai had been. So much for... whatever he'd thought the possibilities there were.
