I still wonder why CA was asking about the Tiffany ring...
It seems like I have seen this discussed before but my theory is this:
Jeff said he did not have a kid and did not make a recommendation for an imaginary, kidnapping, murdering nanny.
Then LA said, well, it must be ANOTHER Jeff...
I think CA remembered that KC had (supposedly) gotten a ring from Jeff and asked Jeff about it.
If Jeff said he remembered it, then it would be proof that he
was the particular Jeff that KC was talking about, and she was lying.
If Jeff said he did NOT remember it, then if KC still stuck to the story that he gave it to her (as she did), then she was lying.
I think Cindy wanted to find out if the possibility of another Jeff being the nanny reference, and I think she wanted to see if KC would state that the same nanny reference Jeff gave her the ring. I don't think she cared where the ring was (above its monetary value, of course). And, no matter whether Jeff gave her the ring or not, KC was lying.
