The Heichou
I saw Say Uncle and I think it was an okay episode. I thought the little references to the fans was cute but other than that the ep was boring and weird. I like weirdness but it was a off kilter sort of weird - like the writers were trying to hard to be 'funny and random'. I also noticed a few people get really upset with the episode which goes to show how unnecessary this episode was and instead of wasting an episode, there could've been one that contributed to the plot
Contributing to the plot is what the worst thing that could had happen with that crossover. The main number one reason why many fans of Steven Universe was afraid of the crossover, because it could be canon. Being non canon is what saved this collaborating from opening another gate. One greater than the Derpy gate, Twilightcorn gate, and Pie gate combine.
I'm not going to lie. That episode is the only good episode of Uncle Grandpa ever thanks to the writers of Steven Universe. Unfortunately this means this very same episode is the most mediocre episode of Steven Universe.
The bright side of this, you can skip this episode and it won't have any impact on the intricate story.
