Shaggy Rogers
- Velma Dinkley: With no actuality of wave function collapse, alternative histories and futures are real. I know why everything's different. We destroyed the Entity and by destroying it, it was as if it never existed. So, everything it touched: All the evil, all of the curse, all of the losers in rubber masks and the dumb monster attractions, none of it ever happened. By destroying the Evil Entity, we created an entirely different timeline.
- Daphne Blake: Our neighbors, our families, they've never been negatively influenced by the Evil Entity.
- Shaggy Rogers: It's come undone, all of it. Our actions created a better world where we all have normal and productive lives.
- Daphne Blake: Lives that really aren't ours.
- Fred Jones: Worse than that, gang, we've created a world without mysteries.
- Velma Dinkley: What kind of a world doesn't have mysteries?
- Fred Jones: A world where we don't belong.
- Scooby-Doo: The heart is us. It's always been us!
- Velma Dinkley: Jinkies! Scooby's right. It can't devour us now and it couldn't touch us earlier, remember?
- Daphne Blake: Not when we stood together.
- Fred Jones: The five of us.
- Velma Dinkley: Our friendship.
- Daphne Blake: Our love for one another.
- Shaggy Rogers: Like, that's the true Heart of the Jaguar!
- Scooby-Doo: And that is something that monster can never take away. Something it can never defeat. It's now or never. Let's do this!
