This post is here in lieu of a series of reaction posts for
the individual episodes in Steven’s Birthday Week. I’m planning on using it for
reference when working on new theory posts for Steven Universe.
- Ruby and Sapphire
 - Sapphire was a member of nobility, and her future vision was valued by her diamond, Blue Diamond
 - Before meeting Ruby, Sapphire was even more resigned to fate
 - Sapphire’s future vision before fusing with Ruby only showed one path. It’s not clear if fusing with Ruby or reflecting on Ruby’s actions when confronted by Pearl caused this change
 - Rubies are common gems that serve as bodyguards and possibly foot soldiers
 - Rubies seem to have a uniform
 - Garnet
 - Her appearance was a lot more mixed between Ruby and Sapphire's traits when she first formed
 - Ruby and Sapphire’s fusing has always been quick and simple. The dances seem to be for show or perhaps to help meditate on the fusion form
 - Ruby and Sapphire spend so much time fused that between the flashbacks in “The Answer” and now that they and Garnet know what Garnet is supposed to look like
 - Garnet connected surprisingly well with Peridot and may be the Crystal Gem that Peridot is closest to
 - Garnet may have been the first fusing of two different gem types
 - Steven
 - Because of his relationship with Connie, Steven is interested in both a human life and gem life
 - Steven’s status as a new creation seems to cause some discomfort for him because of the unknowns
 - Steven’s really emotionally invested in trusting people
 - He views fun as something necessary to make life living
 - Music comes fairly naturally to him
 - Peridot
 - Very much indoctrinated in Homeworld ideas, which is going to make being a Crystal Gem hurt for a while
 - Highly values logic and completion
 - Really needs to work on her social skills (why doesn’t she just ask Greg if he can fly?)
 - Learning really motivates her to interact with people
 - She wants to be viewed as funny by Amethyst and seems to want Pearl to view her as fancy
 - Pearl
 - At the start of the rebellion, she dual-wielded swords instead of using her spear, so she may not have learned how to summon a spear until later
 - Viewed as very ferocious by Homeworld during the rebellion, probably because a warrior Pearl was such an unusual concept
 - Seems to be the least attached to Peridot because she wasn't as upset about Peridot's betrayal as Amethyst and Steven did
 - Amethyst
 - No one seems to fully grasp her insecurities about the Kindergarten
 - Really enjoys joking around with Peridot and views her as a friend
 - Lion
 - Has the disposition of an overgrown house cat
 - His Lion Warps seem to be influenced by physical distance
 - The Diamonds
 - Yellow Diamond really hates Earth. Maybe she took Rose’s rebellion personally
 - Peridot’s indoctrination to Yellow Diamond involved her viewing Yellow Diamond as the paradigm of traits that she valued the most
 - Sapphire and most likely Lapis Lazuli were part of Blue Diamond’s court. Both are the two gems most resigned two their fate
 - Blue Diamond’s Pearl seems a lot more passive than the Crystal Gem Pearl and Yellow Diamond’s Pearl
 - Blue Diamond herself may be relatively passive and prone to leaving things up to fate
 - Gems in General
 - Shapeshifting and stretching require a lot of energy
 - Gem’s bodies automatically adjust to changes in gravity
 - Gems don’t use fabric
 - All Pearls and Rubies shown have the same shape/cut for their gem, but different placements
