I figured Tara was suffering from severe retardation for not knowing how to get out of those knots. I gave props to Franklin for picking a victim too stupid to know the difference. I think Andy covered for Jason because he didn't want him to have to live with the stigma of being a killer in such a small town, probably still coasting off of their buddy mentality holding over from attacking Mary Ann. Then it flipped around and people started hailing Andy as a hero, and suddenly Jason doesn't think he did him as much of a favor anymore. I thought it was really dirty of Jason to blackmail Andy when it seems like he was just trying to help him out.
