On the last night before the bonfire, you got to keep the Cedarcrest Cup in Cabin 12, as your prize for winning Colorwars.
All of the campers are so excited that they can't focus on anything else. They pat it, hug it, try to throw things in it, ping its sides to make it ring, decorate it with streamers and ribbons (all green, of course, except for a few pink ones from Justine). It takes a very, very long time to get them all into bed.
Late that night, after everyone is asleep, you carry the cup out to the Timeless Circle.
"I knew I was not wrong to put my faith in you," Josephine says. As always, it's not a compliment, just a statement of fact; she gave you a task, and you fulfilled it. "I will speak to Tom, and he will arrange matters at the camp such that the cup will not be missed."
You've done what you set out to do. Now for the rest of your plan.
The Last Day
