I poked through the DJ’s stuff, scattered on the second bed. An ancient laptop, an ancient MP3 player, decent-looking headphones. More pills. A twist-tied baggie with a brown lump in it, another baggie of what looked like ground coffee. A few T-shirts, one pair of ragged jeans.
She emerged from the bathroom in a towel, the picture of good health.
“Do you mind?” she asked, and I moved aside for her to take a pair of underwear off the pile. She poked her finger through a hole in a seam. “I didn’t think about this part. How I’d have to wear someone else’s used underwear.”
“Was it worth it?”
She cocked her head, gave me a sad, unstained smile. “That’s kind of up to you, I think.”
I hadn’t considered it that way, but as she said it I knew what she meant. If I told the authorities—whatever that meant in this context—the real DJ would still be upstairs in the fridge wearing someone else’s clothes. It would all have been for nothing.
“Why?” I asked. “Why her, specifically? What’s the divergence point?”
“There are a hundred thousand divergences between her and me. She wasted herself, wasted her life. She was a decent DJ, but she was otherwise a total fuck-up. Tried a hundred times to get clean. It never stuck.”
“She was nice to me,” I said, thinking about our brief interaction, her jittery enthusiasm. “Seemed pretty cool.”
She pulled on the jeans from the bed. They fit, but not as well as the designer pair she’d worn the day before. “I researched her for a while. Trust me. She may have been nice, but she was a four-alarm fire. Smoked everything in her life other than music.”
“But just because she was a mess doesn’t mean she deserved to die. I mean, you’ve still got a lot going in your life, right? You invented cross-dimensional travel. Why would you want to take on her life if you think it’s so shitty?”
She reached into the backpack on the bed and withdrew the DJ’s wallet. Pulled out the ID and tossed it in my direction.
Oh. “Seattle’s gone in your world.” It wasn’t a question.
She nodded, tears in her eyes. “Not only Seattle. Everyone. I lived in a house with five of my closest friends during grad school. I was visiting our parents back east when it happened, but everyone else was in the house when the earthquake hit. I was on the phone with Kelly when it happened—they were all watching Labyrinth —and I heard the whole thing. It took ten days to dig them out. Too late, of course. They all still exist where the DJ’s from, and she sits in her shitty apartment pretending they’re not out there. Ignoring their calls when they try to check in on her. Estranged from our parents and sisters. She never even met Mabel. There are a million Sarahs I could have chosen and wouldn’t have because they still had people.”
“But you still have other people,” I said. “What about them?”
“My lab staff might miss me, but that’s about it. Mabel left me the night I made my big discovery, when I skipped out on our anniversary dinner because I was on the verge; I got home to tell her and she was gone. Our family would have felt terrible, of course, and I felt terrible about leaving them. But they would have been comforted by the way I lived and died, I think. Knowing I did everything I had set out to accomplish. It was a good life. They knew I loved them.”
“A good life you’re willing to leave behind?” I was still trying to imagine that. “You’ll trade tenure and fame and everything for whatever she’s got left?”
“That stuff is good for my ego, but it doesn’t matter. Not like having a home. Not like people. I’ll trade it all in a second for a world where everyone and everyplace I love still exists. Where I could find her world’s Mabel—they never even met!—and see everyone else again.”
“Even if they hate you?”
She didn’t hesitate. “Yes. Relationships can be repaired. Even if they hate me, I know they’re still out there hating me.”
“And that was worth bashing her head in?”
I watched her face carefully. I could imagine the horror I’d feel if I’d lost everyone in such a terrible way, and the guilt of knowing I’d have been there with them if I hadn’t been out of town, and even sitting on one side of that haunting phone call, but I still didn’t think it would drive me to murder.
“She didn’t feel it. Dropped like a stone. She doesn’t even own a bra,” she said, rummaging in the bag. “I haven’t gone out without a bra since I was twelve years old.”
“You did last night. I saw you in the back at the keynote.” I watched her pull a T-shirt over her head for a band I didn’t recognize. “Why did that other quantologist take your place? The real R1D0?”
She sighed. “If I say we’re exactly the same, I mean we are exactly the same. Literally the only difference in our lives is that the night I actually made the discovery, she went out for an anniversary dinner with Mabel, and I cancelled dinner and stayed in the lab. That’s our divergence point. She’s pissed she didn’t stay in the lab that night. She wants the glory. She’s let that supersede everything else, thinks she’d be happy if only she were in my shoes. That’s all. I mean, I’d be pissed too, but I don’t think she’s seeing clearly. She’s still with Mabel. That matters way more than a name on a paper, even one this huge.”
“Her decision must have been spur of the moment,” I said. “I think she heard the call you made, and switched clothes with the body when she realized she was the first one there. I’m not sure why she took both radios, but maybe that was panic. I heard the second one inside her room when I was standing in the hall with her. Anyway, I saw her speak last night. She could be you perfectly.”
“She is me. Nobody will know the difference. She can have them. Now I don’t have to feel guilty about leaving my family, even; it’s her world that’ll have to deal with her absence. Anyway, she might have been headed up to the club to do exactly the same thing I did.”
I shuddered to think that was true, and how many murderous Sarahs actually existed in that case. “Was that your whole motivation for going into quantology? To switch places?”
“No! We were already in a physics masters program, so finishing that degree and going into quantology wasn’t a stretch. We wanted to know if there really were realities where Seattle still existed. Where Kelly and Taylor and Allison and Scott and Andrea were still alive. Not to go there, just to know.”
I didn’t know who Andrea was, but Kelly and Taylor were my best friends other than Mabel, and we’d all lived in Scott and Allison’s house in Capitol Hill when I first moved to Seattle. I couldn’t imagine the guilt of living in a world where they had all died and I had been spared by some quirk of timing. And Mabel had broken up with her on top of that. She’d lost all of them. Even hearing her say it, it hit my gut as if I’d lost them myself.
“So you weren’t always going to kill someone?” I was still having trouble imagining this ambitious Sarah ditching everything she had to become a DJ, but it didn’t seem as far-fetched anymore. Something else bothered me too. I believed everything else she’d said, but I still couldn’t picture myself bashing in somebody’s head, or taking the time to position her beneath the stage in the hopes of making it look like an accident. Every step screamed intention.
She ran her hands over her short hair, smoothing the flyaways. “I only decided for certain when she came back with her second crate. She must’ve gotten herself messed up in between; she could barely answer my questions when I tried to talk to her. Anyway, I’m sure there are other realities spawned at that moment where I decided not to.”
