Yeah, it's not worth it. Safer to just keep going with your own plans no matter what Ms. Martin does or doesn't know.
The next day, you've finally got your break—a real one, this time, actually scheduled. (Pearl's is tomorrow.) For once, nobody will be looking for you, or looking too closely if you go wandering out in the woods. So this is your chance to go to the Timeless Circle.
You could learn more from Josephine. Maybe get an actual lesson in magic from her! Or you could spend more time talking to Lianna.
Or, you could get to know the other people in the Timeless Circle. There are a lot of them, and you've spent more time spying on them than hanging out with them. On the other hand, maybe you don't want to spend your afternoon with a bunch of random grown-ups? You're pretty sure that Lianna was the only person younger than about thirty in the Timeless Circle. But if you do, then you can ask Marcus about his family, and see if he can influence the way his relative votes on the Camp Cedarcrest board of directors.
Or, you could not go there at all. If you spent that time investigating the magical conduit that runs between Camp Cedarcrest and the Timeless Circle, you could learn a lot without having to talk to anyone.
What do you want to do with your free time?
