OK, so team KC is conceding that Zanny was a lie. Are they hoping that it is glossed over quickly in the trial so they can move on to a better lie?
IMO, the Zanny story remains very important as KC went to great lengths to convince her parents that she existed and went so far as to give 3 names to the 911 operator, claimed the nanny lived at Sawgrass to the point of giving an actual apartment number, car description, etc... this went on for months. CA claimed she actually had a phone number for Zanny and both CA/GA "described" her as a "ten." KC even told the 911 operator that she spoke to Caylee on the phone just a couple of days prior to CA reporting her missing. I think team KC is trying to downplay the story and the lengths to which KC went to make Zanny's existence more believable (remember the supposed car accident, going to Tampa General?). All of the other stories/lies that followed the fake Zanny kidnapping, didn't garner near as much effort from KC as the original, and IMO, this is important. Team KC knows it's bad, therefore they are going to do their best to give it as little attention as possible.
