My great-granddaughter is married already. The thought gets filed away, to chew on later when he has time to really consider it. So does the fact that Dr. Kujo doesn't share his last name - neither does Jolyne for that matter. That stirs something in him, a mixture of disappointment and curiosity. So this is his daughter's son, most likely - he isn't sure why, but he feels distinctly bothered by the whole thing. Maybe just from the worry that his family name is dying out.

"Sure, it's just a pocket telephone. Sooner or later we were bound to figure out how to get rid of all those pesky wires - the telephone itself works with radio waves, so it just needs enough electricity to power itself. I assume nowadays, batteries must be much smaller and stronger than they used to be."

He does copy down their information, and he's pretty happy to have his first few contacts be family members. If he can manage to get along with them, that will make the transition to this new world much easier.
