I'm anticipating how the defense and their expert might handle JA's newfound strong demeanor on the stand as she is cross-examined by Juan. I imagine she will continue to be somewhat defiant and difficult. IMO that will expose the real aggressive, manipulative JA.
The defense will counter that and if we think back to her testimony on direct, there were several times JA said, "I wasn't as assertive back then" or "I didn't stand up for myself then". Pretty sure that's a central theme to her script and plan (with help from the domestic violence expert). There will be some expert testimony like since she's had time to reflect, since she's been safe in jail, safe from the abuse she's learned to stick up for herself which she never did when she was in the "abusive" relationship with Travis. Which of course IMO is total BS. But I'm quite sure that spin is already set up.
