This case is all about cause and effect — how one change ripples out and changes everything after it.
- What was the one small thing the agents changed in the past? Why did it matter so much?
- What does it mean that they "undid every case ever solved"? How is that connected to the change they made?
- To fix things, the agents had to put events back in the right order. Why is order so important?
- Tell about a time one small change led to a bunch of other changes — like a domino effect.
