Ewww... just ewww. Wouldn't put it past her.
I got the sense that she wasn't 'getting' where Nurmi was trying to lead her, so her answers were not what he wanted (in her mind she thinks, "NO one is going to humiliate ME!" imv), until she finally caught on with the "doormat" etc. routine...
I think every word of her testimony is backfiring - BIG TIME.
If she pled guilty right now it could mitigate her down to LWOP because she could argue that she did it to spare Travis' family/friends. Otherwise, I think she's absolute toast.
Selfishly, I'd want her to do it after cross... she's not smart enough to consider such a thing, but it's fun to hypothesize...
