I agree...it's not relevant. I'm also not buying ANY of her memory claims. None of these memory issues came up until well after all of her other "versions" were debunked so much, that even SHE thought they were ridiculous. All of the wanting to drive by and see his house and wanting to see the crime photos was all about "What have they got on me?" IMO, I see nothing but a sociopath thinking she's smartest one in the room...confirmed by the giggling, singing and make-up worries five minutes after she was pretending to be crying for Travis in the Flores interrogation.
ITA: And don't many killers like to return to scene of the crime? I think the defense is trying to spare her the death penalty.
