[Rosinante returns the smile. Partly because he means it, for the strange robot is someone he does appreciate. They can bond over being the tallest ones here, but more importantly, for some reason Daylight trusts him and he doesn't want to lose that too quickly. It feels good to be liked. He's not used to it. And that therefore makes up the other reason he smiles: because he wants to look like he also regards Daylight as a friend, even though he normally would reserve that word for someone he's far closer to and has known for far longer.

Sometimes he wonders if he'd grown up around other children if he'd have social skills instead of social tactics, but they amount to the same thing in the end, don't they?]

It's true. We can't even see our way across town in all this darkness. We have to rely on each other a lot more than I'd bet most people are used to doing, so having people you know are helpful is important. Well, helpful, and... Sympathetic, I guess. There's something to be said for that, too.
