Well, they're both insisting they weren't snogging.

Probably means they were.

Dean says about the same as Ginny. I think he tried to give her some advice and she didn't much like it. I think it DID have something to do with all those letters she sent through the journals, and I don't even KNOW what to make of those. Lucius Malfoy? Really? I wouldn't write to Mr Malfoy unless it were REALLY IMPORTANT and he's friends with my fa foster-father.

I'm thinking it probably was NOT really important.
