Sounded like home, huh? He doesn't expect he should take this literally. He's been stuck here on his own amidst all these people from Earth (and a tiny, rare handful of others) for a long time. He has begun to accept that Earth must just be a place so full of people that the odds are always in its favor, or that the idea that alternate-Earths exist is a legitimate one and that by apparently standing on one version of that world, this portal draws in others with ease might have something to it.

But that's all right. He's interested now. An archipelago is still better than - where had Jo said she was from? Or Gregor? Big, vast places that take days and weeks to cross even when moving at high speeds by things like cars and trains. The very thought makes him feel uncomfortable. That much land feels too alien. He'd even rather think of the vast emptiness of space he saw in Will's memories. At least it has something in common with the sea.

"Nobody's ever told me something like that before here," he admits. "Where are you from? Your world, I mean."

If Earth has archipelagos, at least part of it might be okay.
