After 7 episodes of not being around despite being billed as Michael's new hander, Vaughn finally returned, but only because Michael called for him. We still have no clue what's going on, except that Michael now has a meeting with Simon after helping the FBI. It was a foregone conclusion from the beginning, but Vaughn offers Fiona to get Jesse his job back in exchange for Simon's Bible, and of course Fiona sides with Michael.
The plot was a standard save the innocent witness and turn the reluctant hitman deal, which had the usual shootouts, explosions, and contributions from the supporting cast.
Score: 8.4/10
