One thing about this episode that not everyone is going to know, but those "things" inside Kindergarten are modeled after these viruses called bacteriophages (viruses for bacteria). Another clue is that Amethyst called herself a parasite.

So, gems are even less human-like than has been implied before. And now I understand why Pearl wouldn't want to talk about it. If gems reproduce like viruses, then, I mean that's pretty hard to explain to a kid.
