Any sort of stagnation that might have been perceived in the previous few episodes of Jericho was wiped away with "Long Live the Mayor."
The episode does an impressive job of balancing action with romantic subplots. At first glance, it doesn't seem to be about love and romance. But, a number of relationships make significant moves, in one direction or another; i.e. Jake and Heather, Dale and Skylar, Robert and Darcy. However, these plotlines don't overwhelm the episode with emotional elements. On the contrary, "Long Live the Mayor" tends to foreground action and drama.
I actually liked the character Jonah, despite his portrayal as the antagonist. In the post-apocalyptic world of Jericho, it's sometimes necessary to accept that the line between bad and good is a little blurry.
