Synopsis: Homeworld rebels hire the world's greatest assassin to assassinate Steven. Meanwhile, White Diamond meets a new face. 

3rd Person P.O.V.

Obsidian just returned back into White Diamond's room after a long night of investigations in multiple areas. There had been multiple theft charges against an unknown burglar. 

"Having trouble catching our robber?" Her pearl asked, already knowing the answer because of her Diamond's stressed expression.

"It just doesn't add up." White Diamond took off her mask. "Normally, you would see some evidence of the crime, but these thefts all have nothing left behind, not a single trace of this criminal."

"Without intending to sound like I do not care about our urgent problem, but I do need to remind you about your party." Volleyball reminds.

"Right, tomorrow night." White Diamond slowly strips off the costume to reveal her normal Egyptian goddess attire underneath it. 

"My Diamond, it is 'tomorrow night.'" Volleyball corrected her. "You spent all night looking for our unidentified burglar."

"Oh..." White Diamond blushes a pink hue.

"We wouldn't want our guests to grow suspicious of White Diamond being absent to her own party that she is hosting while Obsidian appears to occur more frequent to the public's expectation." Volleyball advises. 

"Right." White Diamond nodded. "Let us set up and organize." 

Elsewhere:

In a dark and desolated spot of Homeworld, resides the leaders of the rebellion, waiting.

"Why are we meeting here?" Emerald asked. "Everyone knows that Steven occurs during the day time."

"Yeah, but Obsidian also occurs during the night time. At least in the day, Steven has to spend his mornings on Earth." Bluebird replied. 

"He won't come here, not in this block." Jasper said, boasting their plan of meeting in this insignificant sector of Homeworld. 

"Oh, I hate him so much!" Holly Blue Agate growls. "He ruined my status!"

"Mine, too." Jasper agreed.

"He took down all of my crew single-handily." Emerald added on. 

"Hello."

Everyone flinched at the new voice. And then they all looked in the direction of where their mercenary stood, her body concealed in the shadow.

Judging by her size, she looked no taller or shorter than Steven Universe himself - which they consider a bad thing. They specifically expected Homeworld's greatest assassin to be bigger than them and Steven. 

She finally steps into the sunlight, revealing that she has most of her body hidden by wearing a trenchcoat and a tophat on her head.

"Eh... are you sure you can take down Steven Universe?" Emerald asked while scratching the back of her head. "You don't look so... tough."

"Looks can be deceiving." The mercenary replied, her voice sounding impeccably calculated and calm. "I will not begin work until I see the Jewels you offered to me." 

"We don't pay up until the job is done." Jasper folded her arms. "Bring us his corpse, and you will get your prize."

And then the mercenary's violet eyes shined from underneath her top hat. "I think you misunderstood the situation. I was not asking if you wanted to show me the Jewels, I demanded you to show me the Jewels."
