Jack tries to be patient. He can see that the boy is thinking. But really, at this point a child would have seen him already. Maybe he should just give up. But then again his belief base is already so tiny, even one more child (who isn't quite a child any more) would be a sizeable gain. He's not aiming for the world here, he doesn't want a big palace like Toothiana or Sandy's power, he just wants to, well. Be seen.

With a little, disappointed sigh he turns. He should let the boy go back before he freezes. But then the boy speaks again and hope warms Jack's heart, turning around on the spot again. "I'm right here!" He says, as he scoops up another snowball and throws it to knock the one that the boy is holding right out of his hand.
