I didn't give it a second thought after AZL ruled her out, but tweets came in that she wore a blazer, it all makes sense now. We'll probably know more on Monday.
This is what fran said:
Jodi put on a blazer over her blouse or shirt. IMHO, she's the witness.
Jodi wanted everyone out of the courtroom, including her family.
IMHO, she's gonna make the testimony during her trial look like a cake walk, as to what she MAY say about the abuse by her mom. She doesn't want her mom in there to hear the new lies?
Nurmi told Arias she didn't have mitigating circumstances, severe child abuse etc. It seems what she originally testified to wasn't mitigating enough. Bet she has a new angle.
Just a guess,
