She sighs. “Not exactly. I thought I had something when you mentioned Grandmother hiding in another time, so I went down a rabbit hole on time-travel philosophies.”

“And came up with nothing?”

“A little bit more than nothing. Albert Einstein thought time was an illusion, a sort of fourth coordinate to show where you are, relative to how fast you’re moving. So maybe that’s what’s happening when you and Beau see the future and the past—you’re rapidly moving forward or backward, but not along length or height or width. That could be why, when you’re slipping through time, nothing around you interacts with you as if you’re solid. You might be traveling so fast you could walk through the cells of a wall.”

“But we’re solid to each other,” I point out.

“Yes, and you also said Beau couldn’t get back to his world the night you met. I believe he used the word grounded. Perhaps when you’re together, you’re tethered to each other. And since neither of you appears to be fixed in the space-time continuum, theoretically one of you could pull the other along at the same speed. And perhaps there’s a looser form of tethering that occurs with animals. Thus Beau’s hamster’s epic journey and your flip-out with your dog. It’s as if the animals are somehow trying to decide where in time they belong and thus bouncing back and forth.” She opens her desk drawer and digs out a Slinky, flipping its metal spirals back and forth between her palms as she thinks.

I raise an eyebrow. “Any particular reason you, an adult research psychologist, keep that in your desk?”

“It helps me think,” she says matter-of-factly. “A physical action to busy the hands. Anyway, I was high while doing aforementioned research, which meant I was messing with this thing, and it sort of struck me.” She flattens the Slinky between her two hands. “What if this Slinky is all of time, and it all already exists—past, present, future—but the human or animal experience is, essentially, moving along a series of moments in just one direction? We can’t see, hear, touch any moment but the one we’re currently experiencing, but they all exist simultaneously.

“That’s why you saw an earlier version of yourself when Beau first showed you how to move time. That Natalie continuously exists just as the You of two minutes ago and two minutes from now continuously exist. But technically human perception should only allow you to see one of them at a time, rather than the million Natalies leading from the parking lot to this office, or the billions of Natalies and Beaus stretched across the highway from Union to here. It’s like you’re moving forward through a flip-book, but there are always other versions of you who are further behind or ahead of you.”

“I think you broke my brain. I don’t get it.”

Alice stretches the Slinky apart, pulling the metal coils taut, then points toward one near the middle with her pinky. “Each of these rings is a moment, and right now we’re both experiencing this one. But then, say you start slipping backward along the Slinky. You’re flipping through every moment that occurs in your current physical space: moving through the Slinky. When the time slip passes, you snap back into place right after the last moment you experienced chronologically, even if by then the You that didn’t experience the time slip has moved to a different physical space.”

“I’m moving through a time Slinky,” I say flatly.

“To be more exact, you are moving through a wormhole that runs through the time Slinky, that lets the version of you in this precise moment move to another moment.”

“And that’s possible.”

Alice’s head wobbles. “Oppenheimer—you know, the atom bomb guy—proved black holes were physically possible.”

“Wait—the ‘I am become Death’ guy?”

“The very same, though he was actually quoting from the Bhagavad Gita. Anyway, Einstein seemed to think wormholes were another logical step. But he also posited that a wormhole wouldn’t last long before collapsing.”

I sit forward. “You think there’s a wormhole in Union, Kentucky?”

“Of course not,” she says. “If there were, we’d all be experiencing time slips. I think there’s a wormhole . . . in you.”

I must be gawking. The idea that an eighteen-year-old girl who’s afraid of the dark might actually encompass a hole in time is almost funny. In an I-want-to-sob-in-the-shower kind of way.

“Think about it,” Alice hurries to add. Her sudden giddiness is in direct contrast to the desolation I feel in my abdomen. I imagine a tumbleweed rolling through my rib cage, then getting caught by the pull of my inner black hole and soaring off into darkness. “If all time is actually simultaneous—and the passage of it is an illusion—then maybe people like us have wormholes in our very consciousness. The other moments always exist, and an anomaly in our perception allows us to interact with them—which makes sense since this all started with a dream state. As soon as your consciousness stops traveling, it tries to snap back to where it should be on your time stream.

“It’s trying to wake up and perceive time as the human brain is meant to—in a linear fashion. Even if you could find the right time where Grandmother’s hiding, I doubt you’d be able to keep yourself there. I’m guessing the Closing is the point at which your perception gets locked back into place and starts moving along your moments as it should—exclusively forward, at a steady pace.”

“There has to be a way, though. If Grandmother can do it—”

“Theoretically, there is,” Alice says. “I don’t know that I’m on the money with all this. But assuming I am, I’m still convinced that hypnotherapy’s the key. Pinpointing that trauma, and using it to stimulate the brain activity that creates the visions—time slips—is our best bet.”

“What about Beau?” I say. “How does he fit into all of this? Is he a wormhole too?”

“Well, that’s the thing that doesn’t add up.” Alice stands and picks her way over to the whiteboard that’s wedged between the bookshelves. She draws a line on the board then starts scribbling branches stemming out from it until it looks like a sideways tree. “This is a totally different theory of time—what I call the ‘many worlds interpretation.’ In it, every decision or action has alternate possibilities. Parallel realities. This is the theory that allows for our Union to coexist with Beau’s, with the division having at some point been created by a decision or series of decisions.” She circles the last two branches she drew. “Hypothetically, even the smallest decision could create two different outcomes.”
