Queen's gag was really well executed.
Not much that they really could have improved upon content wise, since it was more of an information, dialogue episode, but they still did a good job of presenting that sort of stuff.
Kenji Yokoyama was animation supervisor, and his nice art is really prevalent throughout the episode. While not being overly animated, it still looks really nice.
Overall, a really fun episode with lots of visual directional tricks used to make it interesting.
Next episode looks GOAT.
