Lust knew that if she started a fight, she might not be able to win. She wasn't at the top of her game, she was achy and tired, stressed out, Greed was chewing on the back of her mind and even her influence wouldn't be at the levels of managing to cause Theseus pain. Well. Not as much pain as she'd like. But she was Lust, and this guy was a prick. She didn't even bother with a comeback, she just saw red when he got back in her bed. She didn't go for a girly slap, that was a fist that was coming for his jaw.
