Hmm, you know, I'm still pondering how to best express their feelings for Ginny vis-a-vis her obsession with Harry. It's not that they are unconcerned about her. Obviously they love her, but she is a thing separate from them. As long as Harry has made his intentions clear and doesn't flaunt his behavior, they're not going to worry about it.

Of course, they have no idea what is happening with the Pensieve while they're having this discussion. Their reaction to THAT will come later.
