Several days after Jason arrives, Zexion takes revenge on Larxene, with rather extreme consequences.
Day 12: Zexion's revenge: Vexen's room: "well, Zexion, are you sure about this? You don't want to over anger number XII." "I'm sure, Vexen. This should get across to Larxene to stop harassing me." "alright, just checking." Vexen went back to mixing chemicals. Zexion had come to Vexen's room to request a potion that Zexion would use for his revenge against Larxene. After asking his question, Vexen started making the potion immidiently. In the hour or so since Vexen started making the potion, Zexion's thoughts started to wander to Jason. The boy seemed reasonably intelligent, for a human, but his brain was being wasted under the oppressive Larxene. Zexion would have freed Jason, but it was revealed that Jason's family would die if he didn't stay. So Jason was trapped, forced to obey Larxene's every whim. "done." Zexion snapped out of his thoughts, and looked at the beaker in Vexen's hand. It looked like a beaker of mineral water, except the bubbles looked like the heartless crest. " thank you, Vexen," Zexion said, and reached for the bottle. As he grabbed it, Vexen gave an instruction, "remember, say the word, and the potion will take effect." Zexion nodded and left to Larxene's room. Once there, Zexion located Larxene's favorite pair of high heels and poured the potion all over it, then, he put them back and left for the Grey area.
The Grey area, a couple hours later: Zexion read his book as Larxene returned from her mission. Zexion watched Larxene head towards her room, then he read his book some more. When Larxene came back, she was wearing the high heels, and Jason was with her, on the end of a dog chain, as usual. "Alright!" Larxene trumpeted, "who wants to watch me kick Slaveboy around?" in a second, Zexion muttered the magic word, and the shoes turned into Shadow Heartless. "gyuaaahhh!" Larxene screamed, and let go of Jason. Zexion smiled as Larxene ran around and tried to kill the heartless attached to her feet. As this happened, Jason walked over to Zexion and said, "use your powers and hide for a couple hours. Otherwise you're dead." "ZEXION! COME OVER HERE!" "you're coming with me," Zexion muttered, and used his powers over illusion to escape. In another part of the castle, Zexion undid his power. "thanks, said Jason, "but it'll only get worse." "I'll be ok, human," Zexion said, "I've dealt with her before." "please, call me Jason," "human is an improvement on Slaveboy, so be grateful." "true" after this short conversation, there was a silence, then Jason asked a question: "who do I look for if I want strength, but also the knowledge to use it?" "Zexion answered, "number III, Xadlin, is your best bet. If a human like you can survive, you'll earn what you want." "thanks again, Zexion. When my revenge plan is in motion, I'll tell you." at that moment, Larxene appeared with a wicked grin on her face. Zexion and Jason said, "uh-oh" at the same exact time.
