[You know, there are a lot of reactions that Marianne could have to that. Really, she is actually happy, and more than fine with the door being locked because that means nobody will be able to barge in. And if worst comes to worst and Edelgard needs to be in here, Marianne could certainly leave. Or...hide, whichever is preferable.

But that comment about Ferdinand takes Marianne aback, and she's. Not sure what her face is doing but while she nods her head, she looks a little aghast.]

T-that's fine. That's very fine. I didn't know that he felt the need to do that...

[Why is Ferdinand like this, dear goddess above. Marianne honestly sounds pretty exasperated as well. Was that boy raised in a barn or something?

Marianne will straighten up though, letting a small smile come onto her face, letting him lock the door and letting her hands fall to her sides.]

But...I'm comfortable with that. And I really appreciate it.

[...She might be slightly excited, too.]
