None of them remember what exactly caused it. The aftermath took up most of that events memory.
A laughing Ender Pearl, at that point not yet identifying with the name Dream, fell into an equally amused but silent Moonstone, later named Punz, and after a short reforming of light, there was only one gem. One bigger than the two of them with traits of both. One gemstone could be seen on their right eye where the Pearl’s had been. Another gemstone was inside the right hand.
The gem was snickering. Not fully laughing like Ender Pearl had and not as silent as Moonstone had been. The Diamond and Sapphire present just stared baffled at the unknown gem, Green Diamond with stars in her eyes. Once the laughing fully quieted, a pair of green and blue eyes met three eyes of similar colour.
Then one moment their form was pure light and the next Ender Pearl and Moonstone returned.
The second time was just as accidental. It's been a few centuries into their seperation from homeworld. Humanity evolved more and currently they were participating in one of their many festivities. A group of them produced music while other's moved in rythm to the sound. Some of them did so in pairs of two or more.
Not thinking much of it Punz offered a hand to Dream, knowing the other gem loved to test human stuff out. The Ender Pearl took it and not soon after they attempted to follow the human's moves as best as possible.
The melody was nice. Slow but not too slow. The combination of instruments was well chosen but even that didn't matter when they danced with Dream. The world seemed to shrink for Punz until it was only them and their friend. Even the Diamonds didn’t matter right now, neither the ones back on Homeworld nor the one nearby. They hoped Dream felt similar. They hoped XD's presence somewhere around this place didn't matter to him.
They twirled him and in the next moment, it felt like they disappeared.
In the two gems’ place stood one once more. They didn't stop moving, instead danced with themselves. The thought to stop didn't cross them. And when the music faded, so did their joined form.
The third time was intentional. There was about to be a fight one for which they needed to be stronger than before. It’s best to bring out everything they could and that included fusions.
Dream and Punz knew they could fuse. It had happened before. This would just be less accidental. With shared goal and trust, they pulled each other closer and from two became one again.
Their size doubled and with a scythe in their hands they stormed into battle alongside their allies. It’s exhilarating. It’s comforting to be so close to an ally, a friend during battle.
Afterwards, they stay like that for a while longer. They stick together as XD tells them the plan for the next few days. He doesn’t ask them to unfuse like the other diamonds likely would have. Unsurprisingly considering the Obsidian and Aquamarine permafusion. Or the Red Tourmaline and Peridot that are fused 50% of the time.
It's only hours later that they split apart again even though they keep holding onto each other in der little area of their base.

Superhero AU where a city has been protected by group of vigilantes since its founding. The founders fled there after being excluded from other places for one reason or another. For multiple generations that same group protected the place from danger. They have an unofficial leader to act as face of the group.
Dream is the current and one of the youngest of unofficial leaders and one of the most skilled.
Then a guy with silver tongue power starts twisting words and minds. He starts a hero organisation, paints the vigilantes that have been there for years as villains. And enough people listen to join and follow.
