It makes me wonder if the whole thing won't turn into a Batman vs. Joker scenario,..

Lol I like that!
Interesting review of The Unbreakable Kimmy Schmidt, Season 4!
It has happened sooo many times to me when I loved previous episodes and the last one was total disappointment. Based on your review it could be the case as well even though you didn’t mention disappointed, you mentioned puppy getting put down.
