Spot doesn't quite get it, but he can tell there's something there that he's not saying, and he at least knows enough about this kind of life to make a few educated guesses. He nods his understanding - as much as he counts the newsies as his family, he knows he's kept most of them at arm's length too, not wanting any of them to realise the truth.

He supposes Ezra's got secrets of his own, too...

He falls silent, then, not quite sure what else to say. He's never really been a big talker.
