I think, that on her own, Rachel could be a regular person, but she is exhibiting all the signs of spousal abuse, albeit the emotional/mental kind, not necessarily physical. Brendon comes across as a classic abuser. He first berates her, then convinces her that he is the only one who really cares about her and she is buying 100%. They need to be separated ASAP. Hopefully, Brendon goes out before jury, and Rachel can stay in the house or jury in safety for a few months.
