There's basically no one else Sandor would bother going to look for. Either they've demonstrated they're more than able to take care of themselves (by his standards, even) or he just doesn't give a shit. But the kid's physically more vulnerable than most, and young. He can see how some of the others might take it into their heads he's the one to go to for answers-- and wouldn't put it past most of 'em not to go after those answers the hard way.
So when Sandor doesn't see him for more than a few days in a row, he decides it's time to find him. Harder to do than it sounds, for someone as good at hiding as Rat. In the end, he finds the kid by accident, curled up in one of the observation decks on the upper floors, playing fetch with one of his little pets.
Suddenly awkward, Sandor doesn't know how to admit he'd been concerned, especially since the kid's clearly fine. So he goes for gruff instead-- easier, more familiar. "Still not sick of the view?"
