Fusion (short)

"The Classroom Gems: Fusion" (referred to as "The Classroom Gems: Special Lesson" in the title card) is a Classroom Gems short.

Synopsis
The Gems teach Steven about Fusion.

Plot
The episode starts with Garnet punching the title card and yells that she's going to teach the viewers about fusion, thus unfusing into Ruby and Sapphire. Next, Pearl explains about fusion, while the four perform separate fusion dances: Ruby and Sapphire fuse back into Garnet, and Pearl and Amethyst fuse into Opal. Garnet explains further, as Opal loses her balance and unfuses back to Pearl and Amethyst. An irked Pearl berates Amethyst for not collaborating, but Amethyst retorts, doubting Pearl's collaboration. Garnet then shows a clip of the several fusions throughout the show, including Sugilite and Stevonnie. Steven interrupts with a question asking what the main purpose of fusion is. With Garnet's prompt, the Crystal Gems subsequently fuse into Alexandrite, pose, and answer with "Love!" The episode ends with a title card saying "Class Dismissed".

Trivia

 * This is Opal, Sugilite, Ruby, Sapphire and Stevonnie's third appearance.
 * This is Ruby and Sapphire's first appearances in the Classroom Gems shorts.
 * This is the first successful on-screen Opal fusion dance.
 * However, this is Alexandrite's second appearance.
 * This episode marks the ninth time Garnet's eyes are shown.
 * This is the first time we see Alexandrite being formed on-screen(though her fusion dance has yet to be seen, much like Opal).
 * This is the first "Short" where "Fusion" is in the title.
 * This is the first Classroom Gems short where the venue is not held in a classroom.
 * Opal's chibi design appears to be based on her debut outfit from "Giant Woman", as her outfit doesn't have a sash or shoulder straps.
 * This was the second time Alexandrite was shown smiling.
 * The first time in the episode "Fusion Cuisine".
 * This was the first time Garnet has unfused willingly.

Cultural References

 * When the 3 Gems fuse into Alexandrite, she makes a pose with a background similar to that of the Powerpuff Girls franchise, where a heart background is seen with the girls posing at the end of each episode.

Errors

 * While Garnet was fusing, Ruby and Sapphire's gems switch.
 * Garnet's/Ruby and Sapphire's gemstones on Alexandrite are on the bottom set of arms instead of the top ones.
 * However, there is no rule stating that multi-limbed fusions need to keep their gemstones on the same pair of limbs after every regeneration/re-fusion.
 * While Garnet, Amethyst and Pearl have their current, post-regeneration outfits, Opal and Alexandrite's chibi designs appear to be based on their old, pre-regeneration forms.
 * When Steven asks what's the best reason to fuse he is not in chibi form.
