Lucifer just rolled his eyes and took that as his permission to leave (Like he needed it, he knew he was probably gonna be fine. Even if he wasn't knowing him he wouldn't want to make himself seem weaker then he probably looked like from this perspective so he probably wouldn't say something to stop him.)
