Blue Goldstone's Links
>Blue was the first gem to see Ben's surgery scars. Granted, it was on accident while they were sparing, but Blue didn't react negatively to them, just assumed they were the human equivalent to a gem with a crack in it.
Two best friends who make up for each other's weaknesses.
Blue being the youngest (and thus the least experienced), and Ben not being a full gem, means they spend a lot of time together. However, Ben found that Blue is into most of the things that he's into, like Nintendo games, and pranks.
>They know that they stay home "for [their] own safety", but they both hate being babied (Blue doesn't mind as much).
>They both makeup for the other's weakness, shown symbiotically in Blue's ax (offense) and Ben's shield (defense).
>The two fuse to form Pink Goldstone.
