Finally, to Darby's surprise, "I sure do miss my Pop," Chick confided abruptly.

Chick is still at the age when he needs his father. It won't be long before he realizes "Cat's in the Cradle" by Harry Chapin isn't a sad song at all about a son becoming like his absent father; it's a song about a son realizing his dad never really cared and so he doesn't care about his dad anymore. The son doesn't grow up to be just like the dad; the son just chooses, now that he has the option, to not associate with his father any more. The son is off spending time with his kids who have the flu instead of ignoring them with work. The song tries to make it seem like the son grew up to be obsessed with work and care little for family life but we never actually get a picture of the son's family life. We just know the son grew up to not want to spend time with his father for reasons the listener completely understands by the end. For those of us who grew up with a mostly absent father, the song isn't a sad ballad; it's a fucking anthem for sticking it to your dad.
What I'm saying is I hope that one day, Chick can grow up to stiff his father just like his father stiffed him and to not give a rat's ass about him.
"I sure do miss my Pop"
"Pop" can be a regionalism for "soda" but it probably isn't in this case because it's capitalized and Chick's father abandoned him. So it's probably what you thought it was when you initially read it. No Pepsi subtext here!
