[Oh no, that's precious... Jaeger squeezes his hand reassuringly, but otherwise he doesn't keep his grip too tight in case the kid wants to pull away.]

You remind me of someone I know. He's a wonderful person, someone who always does his best and works really hard. He's very smart too! He can be a little shy, and sometimes he doesn't know what to say, so he's very quiet. His name is Albert, and I came here to look for him. I haven't had much luck finding him so far, though.

[Part of it is talking to fill space, to do what he can to try to keep the child calm (although he seems remarkably calm given the circumstances) and part of it is because he wants to see if any of that will get a reaction out of him.]
