Barry and Joe in “Unfinished Business”

Barry

Listen, I've been thinking about Wally some more.

Joe

Are you gonna talk to him again?

Barry

No, I'm not.

Joe

Why not?

Barry

Because he's your son, Joe.

Joe

I know he's my son.

Barry

No, what I mean is, he's got your values. He's got your inner drive to help people do what's right. We're supposed to think we're something we're not until we become that thing. That's that path that Wally's on. I'm not gonna stop him from being the hero he's gonna become. I really don't think you should, either.

Joe

[in good humor] I can't wait until you have kids and they torture you. I'm gonna laugh in your face.

Barry

[amused] All right, Gramps.

Joe

"Pa-pa".

Barry

What?

Joe

My grandkids are gonna call me "Pa-pa".

Barry

[walking away laughing] All right.
