Nostalgia.
It’s delicate, but potent…
Teddy told me that in Greek, nostalgia literally means the pain from an old wound.
It’s a twinge in your heart, far more powerful than memory alone.
This device… isn’t a spaceship, it’s a time machine.
It goes backwards, forwards.
It takes us to a place where we ache to go again.
It’s not called the Wheel.
It’s called the Carousel.
It lets us travel the way a child travels.
Around and around and back home again, to a place where we know we are loved.
