so i'mma tell you a brief summary of the history of su.

Basically, Homeworld is where a lot of the Gems lived. However, Homeworld was about to attack Earth and a gem named Rose Quartz (Steven's deceased mother) thought that was bad. They engaged in a war, and Rose and her army came out victorious. They moved to Earth to protect it from further harm. Soon, a human named Greg came along and fell in love with Rose. After that, some stuff happened (not dirty stuff i just don't wanna explain all the flashback happened) and Rose get pregnant with a boy named Steven. Rose died while giving birth to Steven and now the Crystal Gems (Garnet, Amethyst, and Pearl) protect the Earth along with Steven.

The reason why Veridite was so wary was because she didn't recognize them as part of Rose Quartz's army. If you are not part of Rose's army, you are usually assumed as a Homeworld Gem.
