This episode is exactly what the series needed. I was worried we were headed for a sophomore slump, but "Oversight" had everything I love about Jericho or any tv show. Maybe it was the perfect music or the lack of sleep, but I got teary-eyed when I saw Bonnie in Stanley's arms (I'm not a crier). I loved Bonnie's character, but I don't feel as upset or annoyed as I usually do when a major character is killed off in one of my shows. I feel like her murder was a well-chosen, well-thought-out, well-executed plot development.
Speaking of well-executed, the acting in this episode was incredible. It's definitely improved since the pilot.
