While I don't know Jeff from a hole in the wall, so no idea of his truthiness, I absolutely agree that IF this happened then Molly would be more likely than not to deny it, especially if she gets the sense you're fishing for the same.
It also means, Jeff, more likely than not, if you do repeat, now that she knows you spilled the beans, she's not going to be happy with you. Heh. So yeah, you probably won't get it again.
This is another reminder that from time to time fun stuff can happen in those last appointments of the day.
