[Momo doesn't get any more short with him, at least, but he does arch his brows a bit at that suggestion.]

I know you're out of it, but you were also pretty happy to avoid this problem until I closed the loopholes asking about it. If you leave now I don't really have a guarantee I'm going to be able to find you again. So if you just need to clear your head, I'd feel more comfortable if I could come with you to outside the city and then you can have some time to yourself.

[If he's going to "clear his head" within the city walls then it's not exactly any different to the "it'll probably be fine" take from earlier, which Momo doesn't want to risk.]
