Momoko was still a bit stuck on how she totally didn't think this was anything to do with the girl. Except in how she totally wasn't good enough for Priestly, of course.

"Of course we did it for Priestly! Why else would we leave our jobs and come all the way to another wor... country?" She could totally be kicked out of the academy if anyone found out she'd left without permission! "And we totally thought we'd see Priestly not pretending, too. If we'd just walked up, he'd totally have put up a front just because he doesn't like people thinking they know what he should do."

Or, rather, he'd piece things together and kick them off his planet and never feed them ever again and tell Dinah and Dinah would lecture them and get stubborn about helping Priestly and then it would be even harder to get her to date him and they would never be happy!
