Steven The Sword Fighter is about Pearl trying to show Steven actual sword fighting and not ridiculous sword fighting stunts existing only on television. That leads to her poofing, of which is when a gem takes too much damage (that could cause death to a human), they would revert back into their gemstone and it would be a little bit until they reform (with a possible new costume afterward). This is the first time it happens in the series and would be another important thing in the series. It is another deep episode with that. It seems like they're not too hesitant on tackling the serious and important parts of the series earlier on. With the depth in Steven Universe, it's near a TV-14 rating but it's not quite enough and is just TV-PG. Steven Universe is a pretty serious show that is done under a TV-PG rating. I have thought about a possible sequel series to Steven Universe Future that takes place nearly 200 years after future and drafted 2 episodes and how I want it to go, it would have a harsher rating and would hone in on the serious elements. For the overall importance in the entire series, I give it a rating of 9/10 or 10/10. For Nostalgia, 10/10.
