As oblivious as Lex was she noticed the wince; she had a habit of noticing the things she wanted to notice but she couldn't figure why.

Nope...nothing was coming to mind so she disregarded it. "Yup, much better!" She said looking at the corrections he'd made.

"Through the work of curious people. There's always this one guy who'll want to know what happened, when it happened and why. That guy's usually all for spreading the news and taking the credit afterwards so he'll spread it. This leads to the introduction of people who just like gossiping and getting stuff around. You can always count on them to get the story further and the more people know is the harder it is for the story to die. So like, not everyone saw Professor Burbage get taken but they heard about it from others in the class and probably passed it on as well."
