Theodore smiled down at her when she pulled back, hands stilling. He wasn't sure if she meant to go to bed to sleep, or to continue what they were doing, but either way, it sounded good to him. Although, the mention of it being late reminded him that he had to work in the morning, and he sighed slightly, resting his head against hers. He was still smiling, though. "I'd really like it if you spent the night," he said, meaning it. "I don't know what time it is - but I do have to get up early tomorrow. You don't have to get up with me, though, I'll change the wards for you before I leave -- I meant to do that tonight."
He really wasn't in a coherent enough frame of mind to manage complex magic like that tonight, though. Which he figured she would probably (hopefully) understand. Not that he needed to change the wards to let her leave, but she'd need them changed for whenever she wanted to get back in.
