Istredd gives him a long skeptical look and stops, reaching out to take Lucifer's arm and stop him too. It doesn't matter they're in public, it's starting to get dark anyway, and he may as well be staring right into Lucifer's soul at this point. If he had one.

Let me be clear. Lucifer already told him exactly how he lied. He saw it for himself. It's the only way he's a good liar too, as they've already communicated. If the answer is no, that's fine. I have details of my own that I can't share with you. It's unfortunate, and sometimes it does make him deeply sad that he can't share everything with someone, no matter who it is, even the man he loves. But it is reality. He doesn't live in a fantasy.

Cirilla is going to be protected, no matter what. He may trust Lucifer with himself, but he doesn't trust him with her.

But don't try to play me. You literally told me how you lie on our way to the docks. Istredd releases him and continues on the walk back to the portal. He already mentioned how badly he handled feeling like Lucifer was playing him. He won't handle it well at any point.

For instance, you didn't know that Geralt's from my sphere and that I know him. I also know that he's been your go-between with the Winchesters. Surprise, he can actually keep things to himself. He's only mentioning it now because it is more public.
