We are in the final area, on our way to take down the Wizard and restore things to some semblance of normalcy. For the most part it is really just about beating Christo for me, there just aren't really any other named characters that you spend much time interacting with. While Doublefine didn't really succeed in making me care about the world they did succeed in making me enjoy taunting Christo and I definitely think things will be better without him in power.
However, I should also mention this episode could be frustrating at points, I get through a grand total of one and a half rooms during it and some of the slowdown is caused by me just not seeing key information.
It also doesn't help that a form of the LoadBool function is pretty much uneditable for me, which I suspect is a bug, possible a self inflicted one from much earlier in the series given I cannot find anyone else online with this problem. It is hard to know what is genuinely a bug and what is a flow on effect from things I did earlier in the game.
