The end of "the best seven episode run in the entire series" as I keep putting it is this episode right here. It kinda stands alone after the last few, with a different filming style and weird disregard for everything Duncan might have learned in the episode right before this. It's one of those episodes that I didn't think that highly of at first viewing and then really appreciated what it was going for on repeat viewings. Also, the ending of this episode is what I thought was kinda the pinnacle moment of the whole show as a kid. It was a "the show really made it" moment. It's another episode that feels like it could have been a series finale.
Aired May 12th, 1997. I actually recommend stopping the show after this episode and jumping forward to the last three episodes of the series. That's right, I recommend skipping some ten or eleven episodes. We'll see if those episodes are better than I remember, but as of right now, I think they followed the best 7 episode run in the series immediately with the worst run of episodes. Season 6 is short and kind of mediocre.
"Forgive Us Our Trespasses" or "Duende" would have both been worthy season finales or maybe even series finales. Especially Duende, if it were a two-parter and made into a bit more of a movie. That way, the hours-long waltz of a final battle between Duncan and Consone could have been much longer.
