“I guess your scientists got right on it,” he says. “If you account for the time it took your beetles to get there and the travel time for light to get from Sol to Erid… I think it took less than one of your years to get it done.”

I nod. It’s still sinking in.

“So will you go home now? Or will you stay?”

The… entities… that make major decisions for Erid long ago offered to refuel the Hail Mary. It’s still sitting in a nice, stable orbit around Erid, where it’s been since Rocky and I first arrived all those years ago.

The Eridians could stock it up with food and supplies, help me make sure everything is working right, and send me on my way. But so far I haven’t taken them up on it. It’s a long, lonely journey, and until a minute ago I didn’t even know if Earth was still habitable. Erid may not be where I’m from, but at least I have friends here.

“I… I don’t know. I’m getting old and the trip is long.”

“Speaking from a selfish perspective, I hope you stay. But that’s just me.”

“Rocky… that news about Sol… it… it makes my whole life have meaning. You know? I still can’t… I can’t…” I start sobbing again.

“Yeah, I know. That’s why I wanted to be the one to tell you.”

I check my watch. (Yes, the Eridians made me a wristwatch. They make anything I ask for. I try not to abuse it.) “I have to go. I’m late. But… Rocky…”

“I know,” he says, tilting his carapace in what I’ve come to realize is a smile. “I know. We’ll talk more about it later. I have to get home anyway. Adrian is going to sleep soon, so I have to be there to watch.”

We both head toward our respective exits, but he pauses. “Hey, Grace. Do you ever wonder? About other life out there?”

I lean on my cane. “Sure, all the time.”

He walks back in. “I keep thinking about it. The theories are pretty hard to dispute. Some ancestor of Astrophage seeded Earth and Erid with life billions of years ago.”

“Yeah,” I say. “And I know where you’re going with this.”

“Do you?”

“Yeah.” I shift my weight from one leg to the other. Arthritis is starting to settle in my joints. High gravity isn’t great for humans. “There are fewer than fifty stars as close to Tau Ceti as we are. But two of them ended up with life. It means life—at least, the life Tau Ceti puts out—might be a lot more common in our galaxy than we think.”

“Think we’ll find more of them? Intelligent species?”

“Who knows?” I say. “You and I found each other. That’s something.”
