In the next second, the clatter of Tony's approach becomes audible to everyone. He emerges from the basement dressed in sweatpants and a grease-stained tank top, with black grime under his fingernails and his hair still mussed from the safety goggles he left downstairs, and when he sees who's in the foyer he lights up like a gleeful Christmas tree.

"Obie! Hey, good to see you, man!"

He shakes Obie's hand and then hugs him, laughing, conscious but careless of the hell he is wreaking on that immaculate suit. Obadiah doesn't seem to mind; when he hugs back, his smile is as warm as Tony's.

The difference is, only one of them means it.

When Tony pulls back, he notices Cal at last and grins sheepishly. "Oh, hey." They've met before, he's sure of it, but the name escapes him at the moment.
