Gabriel Hogan as Joe Kennefy, Jr.
Why isn't he listed in the credits?
Also, I'm finally watching this series, as REELZ is re-airing it tonight (watched Episode 2, and watching ep. 1 now!). I don't know why the family/Caroline was so against this series. It doesn't seem to be exploitative of Jack....granted, I've only seen the first two episodes at this point.
I still like John Kennedy a lot....I just hated his womanizing. And his story wouldn't be complete if they didn't bring it up.
