"And now, it's time to find out who's the winner of this year's Halloween costume contest!"
Behind his mask, Kylo Ren sneered smugly. It was more than obvious he was the winner. There was no way anyone else in the temple had a scarier costume than his. He peered around at the younglings standing in line with him on the stage. He sniffed dismissively at their outfits. How in the galaxy could they beat him dressed as Tuskin Raiders, Jawas and Wumpas? He was guaranteed to beat them with his dark clothing, helmet and cloak.
"We've seen some great costumes this year, but there can only be one winner! Only one of you will get these prize cookies!"
Ren peered towards the cookies that sat on a plate on the judge's table, seconds away from being gifted to the winner. He could smell their sweet aroma from where he stood on the stage. These were the sort of cookies that could only be found on the Dark Side of the Force. It was only right they should be given to him and no other competitor. He was sure they were as good as his.
"And the winner is…"
Ren waited with baited breath for his name to be announced.
"…DARTH VADER!"
"WHAT?!"
Ren screamed with all his outrage and disbelief at what he had heard. He was absolutely gobsmacked. He watched with wide eyes from behind his mask as the judge carried the cookies up onto the stage to deliver them to person who'd beaten him. All of his anger which had consumed him burned fiercely.
How the heck could he lose the contest – to his own grandfather?!
"Congratulations, old friend." As he handed the cookies to the winner, Palpatine smirked at him through his hood. "I just knew you'd be the one to win."
Vader just stared emotionlessly at his master as he took the cookies from him. There was no sign of any joy of winning the contest. The only sound he made was his usual sinister breathing.
"How could I possibly lose…" Kyle Ren whined. "…to my grandfather?!"
"Maybe because your costume sucks, dude!"
Ren instantly turned sharply towards the youngling who was jeering at him. His rage increased inside him like water boiling inside a kettle. How dart this little brat insult a dark lord like himself?
That was the last mistake he was gonna make!
Summoning his lightsabre with the force, Ren ignited it, then raised it furiously above his helmet-covered head as the red blade glowed lethally.
"ARRRRRRGGGGGGGGHHHHHHH!"
All the younglings started screaming, each one being silenced as Ren slashed his blade through them. He swung his lightsabre around, unleashing his anger at losing the contest. He killed each of the kids one by one, causing destruction in the room during the process.
"That's my grandson! Go on, Kylo! Kill all these filthy little scumbag younglings!"
Darth Vader watched proudly as his enraged grandson repeated the terrible action he had committed himself years ago when he had turned to the Dark Side. Sitting back to observe and enjoy what was happening to the younglings, he picked up one of the cookies to start eating them – only to find with dismay that he couldn't get them to his mouth.
Not with his mask on.
"Oh sithspit," muttered Vader.
The end.
