"So, what do you want to do now?" Black Onyx asks, smiling as he glances at Blue Topaz.
"We could get to know the crystal gems more," Blue Topaz suggests grinning as she gazes at Black Onyx.
Black Onyx nods, agreeing with Blue Topaz, and with that, they try to get to know the crystal gems more.
First, they hang out with Garnet who teaches them about the importance of fusion.
Next, they hang out with Amethyst who explains to them about the importance of having fun.
Next, they spend time with Pearl who shows them how to summon their gem weapons.
Finally, they spend time with Steven, who gives them a tour of beach city.
"So what do you think of beach city and the crystal gems so far?" Steven asks curiously as he glimpses at Blue Topaz and Black Onyx.
"Everything and everyone seems so nice," Blue Topaz replies as she stares at Black Onyx.
"Yeah, we could stay here for a while," Black Onyx says, grinning as he stares at Blue Topaz.
"Yeah, you both could move in with me and the gems, gem buds!" Steven says, smiling as he looks at Blue Topaz and Black Onyx.
"Yeah, gem buds," Black Onyx and Blue Topaz say smiling as they stare at each other.
Several days pass by, and Black Onyx and Blue Topaz go on some missions with the gems.
They go on missions such as capturing corrupted gems and collecting magical artifacts.
They even practice using their gem weapons with Pearl, and they build their relationship with the help of Garnet.
Blue Topaz and Black Onyx grow closer and closer together as each day passes by.
One, day though, while they're with the crystal gems they go on a mission to the beta kindergarten when Steven spots something land there.
So, they follow Steven and the crystal gems to find out what exactly Steven had spotted.
When they get there they see that a spaceship and a gem is there.
"Another gem," Steven says in confusion as he looks at the others.
"She must be from Homeworld get ready," Garnet says sternly as she looks at everyone.
The other gems nod, agreeing with her, and with that, they get ready to fight this new gem.
The gem has a greenish-gray skin tone, along with spiky white hair, she has a gemstone on one of her cat-like eyes, she's wearing a quartz soldier outfit, and finally, she's holding a gem weapon in her hand.
"Who are you, and why are you here?" Garnet asks demanding that the gem identifies itself.
"I'm Cat's Eye, and I'm here to check on the cluster, and I'm also here for them," the gem replies as she points towards Blue Topaz and Black Onyx.
The gems get ready to battle this new gem.
