I was thinking about when Tiffany in the confusion claimed that Angie referred to David as being the David in the house and I thought if she wasn't lying and it happened, maybe the way this possibly occurred was if Tiffany said to Angie, 'What, David?' and Angie replied, 'David, Yes.' Now the word yes sounds similar to Gest, David Gest, so perhaps in the heat of the moment, Tiffany so hysterical, misheard and thought she did in fact say David Gest.
Maybe I am reading too much into it but the thought crossed my mind that's how a possible mix-up could have played out. I shall have to watch it back and listen closely but I still can't understand why she would lie about Angie having said that, unless she was so angry in thinking that Angie tried to convince her David was dead or something.

Could well be.

"What, David?" - "David, yes" didn't occur I the conversation though I'm afraid.

It may have occurred in the conversation but didn't make the edit.

Dear oh dear oh dear - the lengths people will go to. I don't think that conversation was snipped in any way at all.

Tiffany's behaviour throughout the day was snipped to pieces though. They all seemed terrified of her - she has been very fortunate with the edit.
