Eddie asks her about Jack. She says that Jack and Erin make a great couple and she doesn't understand why they got divorced. Erin says they were a great couple and she thought they were rock solid but they weren't. IT wasn't one thing that led to divorce. It was a million little things. They took each other for granted and had unrealistic expectations and it killed their relationship. But Eddie and Jamie won't let that happen.
Frank is staring out the window when Garrett comes in. Frank says Sid updated him on Garrett helping Abigail. Frank says if Abigail investigates it will make the case unprosecutable.
