Anyone else remember the "Choose Your Own Adventure" genre of books popular in the 1980s and 1990s?

I can't help but feeling that Lynch/Frost offered much the same with these final two episodes of TPTR.

Those who wanted a neat, tidy resolution to TP were given (the first 40 minutes or so) of ep. 17, which basically completes the Coop vs. Bob arc of the TP story. If that's what you wanted, you are free to choose to end the series there.

But that isn't the only the choice that Lynch/Frost offer. And if you're willing so to choose, they offer another option, in the remainder of ep. 17 and in ep. 18.
