Oh goodness!
Watch any old western movie or detective show or super hero movie.
The good guy and bad guy face off. Good guy wins, but lets the bad guy live. Everyone in the audience knows the good guy should have taken out the bad guy, but noooooo.
Then, the inevitable: they meet again and the good guy is forced to take out the bad guy.
Andrea could have taken out the Gov with that knife, a couple of episodes previous, but he didn’t.
Rick could have taken out the Gov last week, but he didn’t.
Had either one of them taken out the Gov, the season would basically have ended already, but they still have a couple of weeks contracted to pay the actor.
What an interesting concept.......I'll have to think about that.
