SPOILERS AHEAD! This is four out of ten of the list, the rest can be viewed at the source.
Bojack Horseman - "Time’s Arrow"In season 4's Penultimate episode "Time's Arrow" it explores the past of Bojack's mother Beatrice while incorporating visual themes of the horrors of dementia. While Beatrice is the bane of Bojack's existence and is the reason for a lot of his insecurities this episode showed us a new side to Beatrice that we've never seen before.
Samurai Jack - "XCIII"While the series finale itself was controversial, the long awaited season 5 started out strong relying more on imagery than words to tell the story. This is especially the case with the second episode of the season with the reintroduction of Aku and Jack confronting the "Daughters of Aku" for the first time.
Steven Universe - "Stuck Together"This episode allowed two of the characters with two completely opposite personality traits to confront each other and their feelings captured on a ship in the middle of space where the situation doesn't look to good. "Stuck Together" truly gave Lars the character development he needed and was the starting point for a great arc for him.
Rick and Morty - "The Ricklantis Mixup"Instead of revolving around the main Rick and Morty we know who takes a trip to Atlantis, this episode is about all the other Rick and Morty's on the citadel making it one of the strongest episodes of the series. The episode showcases the social and political hierarchy of the citadel that wasn't as deeply explored before until now plus a twist ending that left viewers waiting for the continuation of this plotline.
