Oh my gods I am going to kill myself for writing this one. I didn't want to I really didn't but my Damn brain wouldn't let me not write it. I'm sorry Leo! Please hate this please! I don't want anyone to like this it sucks! If you hate people who aren't Leo lovers then you rock! On with this damn one shot.

Leo knew it had to be him. Knew that he was the one who would close the doors of death, but seeing the look on Marina's face made it so hard! Especially since she was stuck in her current six-year-old form. (A/N: I am writing a story called Leo's little sister and well that doesn't have anything to do with this but if you want to read it then you is awesome. If you don't then you still awesome!) Her powers were getting stronger and she was getting weaker. She couldn't transform back into her fourteen-year-old self now.

(Five hour's earlier)

Leo stood on the deck of the Argo II looking at the Door's of Death. In just a few short Hours he was going to go in there. Just him and no one else. Leo had asked Nico to make sure Marina stayed in her room. He knew that if he saw the look on her face. Especially since it was the face of his six-year-old sister. He knew that it would be impossible to walk through those doors. He checked his watch. Only two more hours? How had the time flown so fast?

"Leo?" He heard someone ask. He whirled around almost having a heart attack as he saw the tiny figure emerging from below deck. She was holding her very dirty and I mean VERY dirty teddy bear. She had named it pickles. Leo smiled as he remembered when he had given it to her. And she had named it. Well. Pickles.

"Hey Pip squeak. What are you doing up so early? It's four in the morning."

"I couldn't sleep. I had a bad dream." Marina said. Leo sighed. Bad dreams. Always a worry when it came to his little sister. Always. But know even more.

"Come here Rina." Leo said. Marina walked over in her little nightgown that brushed the wooden deck. Her toes peeped out under it showing them to be painted blue with little seashell stickers on them. He pulled her onto his lap and she laid her head on his chest and began to fiddle with the small gold disk that hung around her neck.

What was your dream about Mijo?" Leo asked. Marina furrowed her brow.

"Well you were there and um you told me that you were going to leave and that this time you wouldn't be coming back. And then you kinda like walked into this light thing and disappeared and I tried to run after you but I couldn't and then I woke up." She stared at Leo. Who felt a lump rise in his throat.

"Don't worry Mijo it's only a dream." He told her. She smiled and hugged him.

"Ok. Thanks Leo. I'm going to go back to bed ok? Love you. Night." She hoped off his lap and ran down the stairs. Oh gods why did I tell her it was only a dream. What kind of brother does that? He thought to himself.

"Well you couldn't tell her the truth she'd be heart broken." He argued. Are you sure she'd be sad though? A voice in his head asked. Does she really love you? Are you really like a brother to her?

"Shuda up Me." Leo growled.

(Time skip.)

Leo stood in front of the door's trying not to look at his friends. Percy put a hand on his shoulder.

"You don't have to do this man." He said. Leo shook his head.

"No it has to be me. You and Annabeth just got out of Tarturus. Nico can't go either. Rina need's him. And she need's you Percy.

"She need's you to ya know." Percy told him. He just shook his head agine.

"I know but she shouldn't I have no regrets about taking care of her. I just regret letting her go. The fire. That night. Well I couldn't live with the fact that I couldn't find her agine. And if she dies… well then it'll feel like it's my fault.

"But it wouldn't be."

"How do you know? How do you know it wont be my fault if she dies? What if she dies trying to save me?" Leo snapped. He turned back around facing the open door's of Death he took a deep breath. Stuffed his hand's in his pockets and began to walk towards them.

"No Leo don't!" Leo heard a small cry from behind him as Marina slammed into him knocking the wind out of him.

"Please don't do this Leo please! Let someone else do it."

"Marina." He warned.

"No Leo no no no." Something broke inside of Leo. He didn't know what or how. But he pushed Marina off of him.

"Isabella Marina Rene Foust listens to me." (A/N; agine. Marina's full name is actually Isabella Marina Rene Foust. But as she was traveling with Leo she started to use the last name Valdez. And her Mom's first name was also Isabella and so she always just used Marina) She winced as he used her full name and didn't say Valdez. "I have to do this it has to be me. Do you understand? I can't have you running after me like some overexcited puppy like you always do. I. Have. To. Make. My. Own. Decisions." Marina's eyes were suddenly filled with hurt. She stumbled back away from him her bottom lip trembling. Oh gods what have I done? Really Leo you're an idiot. You're going to Die and leave your little sister with the memory of the last thing's I said to her were criticism! NO. He knelt down and put his arms around the trembling girl.

:I'm sorry Mijo. I didn't mean any of that." He whispered.

"I. I know." Leo held her at arm's length and stared into her face.

"My brave little Marina. You've grown up and now look at ya. Your six agine. What the hell is going on?" Marina smiled a watery smile.

"I wish I could answer that." She said. Leo smiled and kissed her forehead.

"I love you squirt. I'll see you agine someday. Ok?" He stood up and pulled Marina in for one more hug. Then Percy took her hand and slowly led her away where she ran to Nico. Who caught her in his arms and stroked her hair. He gave his friends on last sad smile.

"Take care of her for me. K?" Then he walked through the doors of Death. And braced his shoulder against them slowly closing it. His last glimpse was of Marina who was crying silently and starring at him. Then the doors shut with a resounding. Boom.

I really hate myself for writgting that. Please Please give me your rants! Please!
