Other than a major bloodbath that really drives home the idea that it's a new regime for Team Rick is Kill or be Killed as they have their vengeance on Team Gareth, the episode was more somber than anything else. It was really about saying goodbye to Bob and I actually liked this episode a lot because of that. Usually on the show, everyone that does meet their end happens in a grisly way. So with Bob infected, it was just a waiting game. I didn't like Bob at the start, but over time the character grew on me. So I was kinda sad to see him go, just like everyone else. As for Gareth, I'm so glad they killed him off and didn't let this drag out any longer than it needed to be.
