- Imagine what happened in/with/to Derry and It in the Bad Future timeline..
- Pennywise, the child eating Eldritch Abomination, knows that Jake Epping is from another Time-Line, and is aware of how to get to them. What if he decides that one Derry, Maine isn't enough?
- In the front cover, what you see before reading the book, you have a newspaper article about JFK's killing in Dallas. In the back, what you see when you finish it, you have a newspaper article about an attempted murder on JFK in 11/22/63. Regarding whether if that's really what happens in the book or not, that's some very clever Fridge Logic artwork design.
