Ivan doesn't get most of it, but he catches 'name' and the questioning tone, so it is easy enough to at least answer the obvious part. He smiles at the man, not yet relaxing because he's not sure if he will get the help, but it seems like the man at least isn't annoyed by having been followed so his chances probably aren't bad.

"Ivan Timoevich."

Using that father's name is still not quite natural to him, rolling off his tongue with no stutter but not as smoothly as it should yet. Since he learned how to talk until a month ago, he used Andreyevich - his mother had had to give the official something, and apparently using his actual father's name had been no option yet, so she had chosen the male version of her own name. But one month again, that had suddenly changed, and now his patronymic was Timoevich. He'd need some more time until it truly felt like his name. At least he hadn't screwed up with his first introduction in this new place!
