" See if you can figure out why they call me Four.”
The door closes behind us, and the room is black. She moves closer to me and says, “What’s your real name?”
“See if you can figure that out, too.”
The simulation begins.
The room opens up to a wide blue sky, and we are on the roof of the building, surrounded by the city, sparkling in the sun. It’s beautiful for just a moment before the wind starts, fierce and powerful, and I put my arm around her because I know she’s steadier than I am, in this place.
I’m having trouble breathing, which is normal for me, here. I find the rush of air suffocating, and the height makes me want to curl into a ball and hide.
“We have to jump off, right?” she says, and I remember that I can’t curl into a ball and hide; I have to face this now.
I nod.
“On three, okay?”
I nod again. All I have to do is follow her, that’s all I have to do.
She counts to three and drags me behind her as she runs, like she’s a sailboat and I’m an anchor, pulling us both down. We fall and I struggle against the sensation with every inch of me, terror shrieking in every nerve, and then I’m on the ground, clutching my chest.
She helps me to my feet. I feel stupid, remembering how she scaled that Ferris wheel with no hesitation.
“What’s next?”
I want to tell her it’s not a game; my fears aren’t thrilling rides she gets to go on. But she probably doesn’t mean it that way. "
