The Crystal Gems basically stole you from your father, Greg, when you guys first met.
Now, you're a year old, the gems and Greg got a long, and now they're taking care of you while Greg is away.
Amethyst ran around the temple, which is now apart of a beach house, with Pearl chasing after you. Garnet just sat there with you babbling away on her lap.
Garnet sat there silently, watching you as Pearl and Amethyst did their usual chaotic bickering.
"Amethyst! Stop right this insistence!" Pearl yelled as Amethyst ran around, a wide smile on the purple gem's face.
"BYEE, P!" Amethyst shouted, laughing as Pearl struggled to catch up.
Garnet just stared at you, smiling a bit as she showed you the two gems on her palms. "Sapphire," She said, holding up her right hand, "Ruby," She said, now holding up her left hand.
Garnet was simply distracting you from the other two gem's chaos.
