It's funny because my take on it was that they wanted to get these two out of the way at the beginning so that the negative impact might have faded slightly by the time the jury deliberates.The brilliance of bringing Cathy and Taylor in first is that many people will doubt their veracity, because, of course, they are not impartial witnesses. But it's clear from the defense's opening and what they've revealed of their trial prep during cross, that as their experts present, Cathy and Taylor's statements will be supported by hard evidence. Bolstering C & T's testimony as the jury reviews it later.
