Marlene was there armed with beer and minicorndogs, because her life is a sad state of affairs.
She was definitely quieter than most people would've remembered her being, especially after the whole "Voldemort is still alive, psych!" bomb was dropped. "How do we know what a horcrux is and where do we find them?"
Marlene would say that setting fire to everything isn't a plan they should rule out quite so quickly >>
Re: the disappearances -- "Do we think that Dumbles is behind that? Or the government? Or is it Death Eater fuckery again? If it's the latter, there's probably old pathways we can take for that. I don't even know where to start with the other two." There's a lot less of them, and a lot more bad guys these days.
