Ok so they have Ava working for the Marshalls so she can keep herself out of prison, but therein lies my question. She was originally arrested for murder, but Boyd ruined that by killing the people that made the case and she was going to be released. Next the guard faked like she had stabbed him, and she went to prison for that. Later though he recanted his statement, and the Marshalls know about that. My question is what charge are the Marshalls holding against her to make her cooperate? She was already cleared of the murder, and they know the guard faked his stabbing, so what do they have on her to make her a CI? They keep saying she is going to go back to prison to face her charge, but what charge are they talking about? From what I see she has been cleared of everything???
