Well, if Peter wanted a threesome with a guy, he wouldn't be asking Lucy if she liked women, would he? Not that she would mind that either, actually. But she'd only really go for it if Peter's also into it, since part of the fun is putting on a show for him. She likes showing off like that. Or she used to. She hasn't actually tried it after the Master, and they had a few threesomes that she was not very into.

She frowns at him. "Peter, I completely understand why you'd be jealous--" She stops suddenly, looking surprised at herself. She meant to say the opposite of that. "I mean. If you were with someone else, I'd be upset."

What.

She gets suddenly to her feet, walking a little away from him, pacing and gesturing agitatedly as she turns back to him. "That's not what I meant to say." That's not what she meant. She didn't mean that. Goddamnit.

"I" don't "need us to be exclusive." Her eyes widen. "Oh god."

And with that she starts walking quickly down the path, panicking, running away from this conversation, because oh god. She's fucked things up now, hasn't she? Peter's the kind who likes to sleep around, he's going to find her clingy and jealous and controlling, and oh god, she may be going through a string of curses in her head that would rival Peter's best.
