Theo rides in the seat next to me, his expression stark as he stares straight ahead. Neither of us has spoken to the other since we got in the car. I don’t think we have any idea what to say.

Then I realize the first thing I need to know. “What was it like when you were, you know—taken over?”

Although he still doesn’t look at me, he relaxes a little. “At first it was like I was just losing time. Blacking out or something. I thought I was working too hard on the Firebird project, skipping too much sleep, something like that. Didn’t mention it to Henry or Sophia, because I thought they’d tell me to take it easy and I might miss out.” Theo sighs. “If I had, maybe one of them would’ve realized what was going on. So, that was pretty stupid.”

“You couldn’t have known.” Inside I find myself thinking of every other Marguerite I inhabited. At the time, I felt as though I was making responsible choices—or that if I made mistakes, they were the mistakes those Marguerites would have made in my place. But now that I see Theo’s profound sense of violation, I wonder if that’s how they feel, too.

“After he started using that green stuff, everything changed. I was aware of what was going on, but it was—distant. Foggy. It reminded me of twilight sleep at the dentist. Then he’d leave. Go back to his own dimension to, I don’t know, report in or whatever. By the time I could feel myself sobering up, he’d be back.”

I remember now, back in the Triadverse, the talk about Theo’s time-consuming “internship” with Conley. Really Theo was traveling between dimensions as Conley’s spy—going back only often enough to maintain his cover story.

Finally Theo looks at me, though his gaze is hesitant. “Once the son of a bitch moved on for good, I could only remember the big details—that they’d done something awful to Henry, that I’d framed Paul for it, and that they were after you. They’d been after you the whole time, and I couldn’t even warn you. We had to wait here, not knowing if we’d ever see you again.”

As much as I sympathize with the pain I hear in his voice, I can’t let Theo keep beating himself up about this. “I made it back. Okay? You have to stop worrying about the past. Worry about the future, because Triad’s definitely going to keep trying.”

“Oh, I’ve been thinking about Triad. Trust me, I’ve been thinking a lot. They had their chance to surprise us, and now they’re going to get a few surprises in return.” Theo actually smiles, but it’s the scariest-looking smile I’ve ever seen. I wouldn’t want to be Wyatt Conley right now.

We reach the university campus. It’s a still place between semesters, almost abandoned, with only a handful of the usual cars in the parking lots and a few forlorn international students wandering around. With a stomp on the gas pedal, I speed us toward the lab and pull into the closest spot.

Josie’s Volkswagen is so tiny that we must look like clowns spilling out of a circus car. As I peer through the darkness on the grounds, I don’t see anyone close by.

Mom steps in front of me. “Henry?” Her voice shakes as she calls his name again. “Henry?”

Then I see what she’s seen—the shape running out of the shadows.

“Sophie!” Dad shouts as he dashes straight into Mom’s arms.

Somehow we all wind up on the ground in a group hug, and everyone’s crying and everyone’s laughing and we probably look like crazy people, but I don’t care one bit.

And yet, down deep, I’m still afraid.

What about Paul?

As we disentangle ourselves and get to our feet again, Mom kisses Dad—and I don’t mean, like, a normal kiss; I mean, she lays one on him. I’ve always been glad my parents loved each other so much, but I never felt like I was watching anything quite this intimate. As I turn my head to give them a little privacy, Josie giggles. “That’s right,” she says, wiping tears from her cheeks. “You weren’t with me that time I walked in on them doing the deed. Seriously Freudian horror.”

“You saw your parents at their best,” Mom murmurs, before Dad sweeps her into another kiss.

“Go ahead,” Josie calls. “Mate in public. Tonight we won’t even mind. You deserve to break a few decency laws.”

I can’t bear it any longer. “I have to go. I have to find Paul.”

Slowly Theo nods. “Come on. I’ll take you there.”

Together we run across the dark campus, past enormous, empty buildings and then into a block of dormitories. They look nicer than I thought dorms would be—more like apartment buildings. The lock on the door is ultramodern: a huge black access-card reader that stops me in my tracks.

“ID reader,” Theo says as he fishes his student ID out of his wallet. One swipe, and the lock clicks, letting us in the building.

Together Theo and I walk up two flights of stairs and along the hallway until we reach Paul’s door. Hoping against hope, I knock and call out, “Paul?”

No reply.

So we stand there in the hallway, with nothing to do but wait.

“You say Paul’s in danger because he’s saving my evil twin?” Theo leans against one wall, folding his arms in front of his chest.

“And the other you, the oceanographer from that dimension. The one who got pulled into this against his will, like you did.”

“Little brother,” Theo says softly.

“You know he’d never leave you when you were in trouble.”
