She's sad, yes. Quietly wounded, underneath. She holds her grief so carefully inside of her. Her relationship with John hasn't always been completely easy and smooth sailing. They've had their moments when they've butted heads. But John is — was perhaps the closest thing to a father in this place. Especially after choosing to leave her own father behind, back home.

When the notebook is returned to her, and there's a few seconds for her to read what he's saying, her expression shifts into one of being completely dumbfounded. Clear out of her way—? She looks up at him with a questioning look for a long moment. He's going to leave? Now? ... Why?

"No, no." she shakes her head quickly. She puts the pen to paper, writing quickly this time. She isn't telling him to leave, she's not telling him to get out. If this was an agreement put into place by John that this man should stay here, live here — then it is absolutely not her place to change that. She wouldn't dare, even if she does find herself the new owner.

Why would you leave? You live here.
