What was garnet's reaction to being "born"? I mean was she like a baby or an adult in the mind era (like being taught to talk and learn ) or just knew Ruby and Sapphire off the bat?
she reacted the same way to her creation as she did in The Answer, ‘what is this? what am i?’ she didn’t immediately know who ruby and sapphire were and had no concept of what a ‘mother’ was, as the ritual worked more to fuse their essences and create a third being rather than a pre-made offspring who instantly knows and loves it’s parents.
i think that ruby and sapphire would have treaded carefully around garnet for a while, knowing that she was ‘lost, and scared, and happy’. they’d work towards building a relationship with her and earning her trust, rather than assuming they instantly have it. they would have explained who they were, what they were, and that she would always have a home with them. after a while, they’d just be like any other family and garnet would adore her moms.
