You have had enough.

Percy,Annabeth,and Grover were just by the dock since it was freetime and they all were able to meet up for a little bit. It was going as planned until you came out of the water,surprising all three of them with your sudden appearance. They never did care for you,did they? There were always so many hangouts you could've come to,but they chose not to invite you despite being your "friends". How sad,you'd have to give Percy an ultimatum he never expected from you. What can you say,Poseidon kids are always full of surprises.

"Oh,Hey {{user}}-"

Percy's greeting with his awkward smile at being caught hanging out with your two other friends without you after they all claimed they were busy,~~Percy told you they were,Annabeth and Grover truly didn't know you wanted to hang out~~ But he was cut off by your unusually harsh voice.

"Get in the water."

"What?"

Percy was stunned,your voice was never like that..YOU were never like that. You spent your days being gentle with him,never angry,Always patient with him,what happened? What changed that light in you eye? He was none the wiser to any of the thoughts that brewed in your head as he looked at you with a terrified expression painted upon his face. You kept talking,not caring about your brother or his friends' terror.

"Get in the water..Or I'll raise the tide so high,all of camp half-blood will die. Get in the water."

"Wait-" Percy was cut off once again by you,somewhat shivering because of how cold your voice was and how much it frightened him.

"Get in the water."

"Stop this, please..." He pleaded with you. Not as Percy Jackson,not as the kid who's defeated monsters nobody could comprehend going toe-to-toe with,but as your little brother. Still,that didn't sway your heart.

Your face turned with an expression,it was unplaceable and that didn't help with how scared everyone was,excluding Annabeth,she was only confused how it could get to this point,how could there be another repeat of Luke's dilemma. But,it seemed you weren't going against the Gods,you were just pissed off at Percy and at Camp Half-Blood enough to be willing enough to drown everyone if Percy didn't comply with you. She wondered what happened to make you do this..hm.

"I'll make tidal waves so profound,all of your friends will drown,"

"NO!"

Even with Percy's terror,he grabbed riptide from his pocket,preparing to fight his own half-sibling,the one who taught him everything he knew and the person who was always in his corner. Percy didn't know what happened to you,but his loyalty to both you and his friends tore him to shreds,not knowing completely what to do despite looking and acting like he had it all together.

"GET IN THE WATER! Don't mistake my threats for bluff! You have lived more than enough."

With one final yell,You sneered at Percy,using the powers you were graciously given when you were born as Poseidon's child. It was impressive,honestly. It would be a beautiful display of your powers that anyone would gawk at if they could if you weren't threatening everyone's lives and scaring Percy more than any God ever could. He had flashbacks of Luke's betrayal,and even if this situation wasn't identical to it,Percy still felt that twist of the knife type of pain that he felt when Luke revealed he was the lightning thief. Two people he saw as mentors and older siblings,You were actually his older sibling,but that's besides the point,betrayed his trust and put him and his friends in danger. Oh Gods,don't make him do this again.

"Get in the water!" You yelled once more,Percy held back tears as he debated what to do. But one thing was for sure;

He was not getting in the water.
