Brain: People treat Eyeball and Aquamarine’s relationship as just a joke, like “they fuse because they hate Steven that’s so silly”, but, at the core, even that it’s all about relating to each other and mutual understanding in an environment they perceive as hostile (they thought everyone was being nice to them because they didn’t recognize them as Bluebird. I would say that’s precisely why they thought their plan was working. But people, again, just took it as a shallow “they’re so clueless” joke).

Me: Yeah.

Brain: Besides, are we expected to believe there’s literally no other gem that hates Steven in the whole galaxy. Aqua-that’s-the-problem-with-you-fusions-sooner-or-later-you’ll-become-sentimental-marine fused with Eyeball specifically, a ruby soldier. Not only it’s a cross-gem fusion, which is something you wouldn’t expect from these two (supposedly pro-era 2) gems, but also one between an elite gem and a low-ranking, mass-produced gem who had probably never met before.

Me: Shh. It’s okay. I know.

Brain: Bluebird talks about their story as something they share (“there were two gems…” “they were cast out, forgotten…”) even though there probably were differences given their contrasting status. They could have explained themselves after unfusing, each talking about their own experience, since they weren’t pretending anymore, but they didn’t. They relate to each other, besides just hating Steven and having a common goal. And it’s so unique to have two gems that are basically opposites to have such similar experiences and feelings. I would say it’s a singularity, including the fact that they had a chance to communicate and discover this (and, of course, fuse), that is quite befitting of Era 3. Also, the way they complete each other sentences sometimes??

Me: Hm-hm.

Brain: I think it’s easy to notice the similarities with Ruby and Sapphire (blue+red, ruby + high ranking gem…) but also when they bicker and fail to fuse they act kinda like Amethyst and Pearl in the early seasons. They don’t hate each other! When they fuse, Bluebird is perfectly stable, she has a unique voice that doesn’t get distorted, her face doesn’t change to appear more like one or the other, she has an unique weapon, unique style of water wings and only one pair of extra limbs-

Me: You’ve already thought about literally all of this before.

Brain:

Brain: I’m still gonna produce serotonin

Me: Okay

Me: Wait where’s the negative punchline

Brain: There isn’t one. Just Aquaball happiness.
