Sure, you just have to head back to the changing rooms to get... Rachel's book?

You left your notebook back in your bag, which meant it would be a simple thing to go back and retrieve Rachel's book from-

Rachel's book?

Oh, that's a problem.

You excuse yourself from the entertainment and hurry back to the changing rooms, only to see Rachel there, a tall brunette from your class who was notorious for slacking off at gym reading her notebook.

She hears the door open, and when she sees it's you, she smirks and closes it.

"Well, well, well. I was very curious about what you were writing, and I thought I'd take a quick peek and put it back," she said, waving the notebook in her hand. "But I did a little test, and _wow, this is very nice._"

You open your mouth to explain yourself, but Rachel cuts you off.

"Hey now. You had all this power, and you spent it on a cheap thrill. Now, it's a fun one, sure," She glances out the window as she says it almost idly, "But you gotta learn to share your toys, Michael."

You only had one question. "What was the thing you did?"
