Madonna and Child.

This time I open my eyes to a familiar face I've never seen before: only a boy, early twenties perhaps, physiologically. His face is a little lopsided, the cheekbone flatter to the left than to right. His ears are too big. And while the eyes below his frown shine with their own bright intelligence, I know immediately that he is natural.

I haven't spoken for millennia. My voice comes out a whisper: "Who are you?" Not what I'm supposed to ask, I know. Not the first question anyone on Eriophora asks, after coming back.

"I'm yours," he says.

I want to let that sink in, but he doesn't give me the chance: "You're not scheduled for this shift, but the Chimp wanted extra hands on deck. We've got kind of a situation brewing on this next build."

"Situation?" It can't be good; the appearance of new crew can only mean the death of old.

"Maybe a contact scenario."

I wonder how many centuries ago he was born. I wonder if he ever wondered about me, before now.

He doesn't tell me. He only says, "There's a sun up ahead. Half a lightyear. It's — flickering. Chimp thinks maybe it's talking to us."

And Chimp's not smart enough to deal with it on his own. They built him that way.

"Anyhow..." My son shrugs. "It's not like there's any mad rush. You've got lots of time to catch up."

I nod, but he hesitates. He's waiting for The Question, but I already see a kind of answer in his face. Our reinforcements were supposed to be pristine, built from perfect genes buried deep within Eri's iron-basalt mantle, safe from the sleeting blueshift. And yet my son has flaws. I see the damage in his face, I see those tiny flipped base-pairs resonating up from the microscopic and bending him just a little off-kilter. He looks like he grew up on a planet. He looks borne of parents who spent their whole lives hammered by raw sunlight.

How far out must we be by now, if even our own perfect building blocks have decayed so? How long has it taken us to get here? How long have I been dead?

How long? It's the first thing everyone asks.

This one time, I don't want to know.
