Of course. No, it's not a surprise, it makes sense that he would leave here instead of coming all the way into the Citadel with her and then having to walk that whole way back again.

It's perfectly logical and whatever her gut thinks as it sinks a little, it doesn't actually get an opinion.

"Well, I already have it in my calendar to come yell at you tomorrow, so..." She lets it trail off, and studies him briefly with a tiny smile.

(She'll see him tomorrow. She doesn't need to try and fix every detail in her head. This isn't a dream, and she doesn't only get this one day.)

"Good night."
