*I don't own nothing except this plot! R.R. owns Percy Jackson and co.* She certainly was the greatest mystery of all. And it drove Andrew Chase insane. Her friends tried to get Percy to open up to them, and each and everyone of them got doused in water from the camp(Half-Blood)'s toilets. As they dried themselves off, Thalia snapped. "What the Hades, is WRONG with her? I mean, I know she snaps and gets aggravated easily. But DAMN!" Her younger brother smiled at her little tantrum. "You done, Thalia?" A death glare was sent to her brother, yet he didn't back down. "I'm just as annoyed as you are Thalia. But maybe, there is a way we could find out, what's bothering her. I already talked to her mother, Sally said she doesn't have any idea either, so we talked to her father. Poseidon(or Neptune) didn't have a clue, so there was only one other person I could ask. Her brother, Triton." Leo looked confused, and said what everyone was thinking. "I thought Triton hated his siblings." The grey-eyed blonde male chuckled lightly. "That's what I thought at first too. But a quick Iris message, and I found out that because Percy is his first sister, he absolutely LOVES her. So I talked to him, and in 20 minutes he's coming here to show us some very important things about her life. Until then let's play truth or dare." The group of demigods and goddesses went to the truth or dare room. Almost 20 minutes later, Leo had a black eye, Thalia was dressed all girly. Grover was covered in hot pink glitter. Clarisse was about to go, when a knock at the door alerted everyone. "Come in!" Thalia called out. In came a young man, who looked strikingly like Percy. He had dark hair that was swept aside. The only difference between the two was Percy had mis-matched eyes. One eye a soft ocean blue eye that changed to a bright sky blue when happy, and super bluish-grey when sad. Her other eye was a vibrant green that resembled a emerald that changed to a bright Granny smith apple green when happy, and a dark murky algae color when sad. This man's eyes were Percy's striking green eye(s). "Hello, Triton." The Son of Athena smiled. "Hello, Son of Athena. Its good to see you, all of you. I must admit, I thank all of you for taking care of my sister when we couldn't be with her." He smiled. "Why don't you clean yourselves up, then meet me I Cabin 3?" 5 minutes later, the group went into the cabin to see Poseidon's oldest, smiling at what seemed to be a photograph book. "Well, in order for you all to help and understand my sister, you all need to understand who she is. Are you reader to watch the life of Persephone Atlantia Jackson?"
