Seth nods quietly, looking away from Daniel and focusing instead of the path ahead of them. He wants to say something comforting, how it's okay, and Daniel is just doing what he has to. But he doesn't think he can manage it.

Perhaps it's a good thing Daniel doesn't know him, because it's painful enough having this conversation. If this Daniel knew Seth as well as the other does (did? will?), it would surely be even harder to discuss.

"We're friends," he says, swallowing and staring at the ground as he walks, clenching his fists a little. "You and me. Where I come from. In an.. alternate universe."

It's nowhere near a complete explanation, and it's not really where he comes from either. Not originally, at least, even if it's where he was last. And where Daniel was last. The other Daniel.
