Lex was looking around and taking in everything for as long as she could. It wasn't everyday that students got invited in here and she didn't think it'd be happening again for a very long time, if ever. While looking, she tried to think of all the places that could light up green.

For all they knew there might have been some epic battle here before Harry Potter was even born and it led to someone dying. That'd be neat! It'd also leave questions because something like that should have been taught at some point. Or maybe it had but she simply hadn't been listening? That seemed just as likely.

Oh. A question. One they'd already covered.

"Professor Binns died in here, he's the one we're looking for..well...the green indicating his pace of death anyway." That was how it worked yes?
