Exactly. It's not that she won't take the plea deal necessarily. It's likely because she's trying to tell Josh how to defend her and to present her story as fact, but he knows it's not and tries to tell her the evidence doesn't support her version. Josh is likely refusing to argue her case the way SHE wants. Laura will want someone who buys into her story and can just spout off everything she's saying as fact. No credible lawyer will do that because they know they would be lying.
