Before the quote for the 21st, Joe can see that after their kiss Carolyn has become somewhat sad, and that's why the script has him saying:
Page 17 - Joe: 'Hey. I can put the trip off.'
And when it comes to the quote for the 22nd -
Page 17 - Carolyn: 'And risk disappointing all those hungry monkfish? (kisses him) I'll see you when you get back.'
- the only part that somewhat survives in the pilot is the last part - the "And risk disappointing all those hungry monkfish?" bit is dropped, and what Carolyn actually says is "I'd better get back." But as Carolyn prepares to leave Joe has an added bit of dialogue when apparently he can't believe that's all she has to say so he asks her "You're goin' out like that?" And to that Carolyn replies with something that no one that I know who's seen the pilot seems to be able to decipher. It's something like "I know (something or other)" but who knows what the something or other is. Though whatever it is, she does say it playfully, so it's not like she's leaving in anger. But she does leave Joe bemused.
