Yes, she was and the experienced DP attorney wrote a note to her and told her to knock it off. In a DP case, the defendant is on stage all the time -- every second --- and needs to act the part of a sober, respectful defendant at all times. The image of her being a fake lawyer and engaging in her own defense both underscores the fakeness (and enhances the image of her as a liar) and gives an impression that she is actively involved in a defense (or cover-up). No point in enhancing the most negative aspects of this case. KC needs to sit quietly, respectfully and attentively but take a completely passive role as if she is without knowledge of this case and it is serious business. This is clearly not the case where she should be "helping" her attorney or part of a defense "team." That image will hurt her and the DP attorney told her to knock it off.
Also, comments were made about CA crying. When the SA put the DP back on the table, CA treated it as if it was just a fake power move to up the pressure to get KC to plea. Now, with the arrival of the new DP attorney, there has been a new reality check. This is not just a bluff. This is as serious as "serious situations" get and the SA is deadly serious about the DP. For the first time, CA is realizing that the chance that KC could get the DP is very real. The DP attorney just removed all of CA's emotional buffer and it hurts. GA was there some time ago; about the time of his suicide attempt. He is stronger now. JMHO, of course.
