Tony might be trying to avoid attention - but the man was probably always going to attract the attention of one of the resident climbers he was imitating. And Link was curious, of course. All the odd metal structures, made from metal beams. They reminded him of the Sheikah towers, just a bit. Would they do something similar?

So as Tony makes him way up one building, he's going to find Link already up on the roof, crouched down and peering over the edge at Tony.

"...Hi," he says. And then holds out a hand, to help pull Tony up.
