The Little Merman and The Little Ghost Boy

What's going on?

～Will's point～ 

I was standing in front of a priest as he talked. Why was I standing here? Right I'm getting married.....why am I getting married? I thought to myself. My mind was so foggy it was hard to think or focus on anything. When everyone started to run and scream and when a dragon landed on the boat I just stood there in the same place trying to clear my mind trying to focus on something.

My mind and thoughts started to clear when I heard a man singing. Then I heard someone called my name and looked up to see Nico. There was a
glowing wind that was flowing into his mouth as he sang and ran toward me. When the glowing wind was gone he stopped singing and looked irritated as if he hadn't wanted to sing in the first place.

"Will!" He yelled in a Italian accent

"N-Nico?" I said confused for a moment.
I'm I hearing things? I thought but before he called my name again and I realizing he was actually speaking.

"Nico!" I yelled as I ran towards him with a huge grin on my face
When we reached each other I threw my arms around him and hugged his tightly

"Will, non riesco a respirare" Nico said

"What?" I asked not understanding what he said. He then pointed at his throat signaling that he needed air.

"Oh, sorry" I said letting him go.

"Grazie" He said as he took a deep breath. He then looked me in the eye and gently caressed my cheek while softly smiling

"Ero così preoccupato per te. sono contento che tu stia bene" Nico said and although I don't know what he was saying the other sincerity in his voice an on his face was enough to make my heart melt.
Nico's eyes suddenly went wide with fear as he focused on something behind me. I followed his gaze and saw the sun setting. Was Nico afraid of the dark? I thought as I watched the sun sink into the ocean and when it did I heard Nico say no over and over again. I looked back at him to see what was wrong and I froze at what I saw. Nico was standing, no floating in front of me. His pants were laying on the ground and instead of legs there was a callom of smoke he looked over at

"Yes! They're to late!" The man and woman who had tried to marry me and Annabeth yelled while laughing. The woman ran at Percy who was now laying on the ground with fins instead of leg. The man then ran and grabbed Nico who tried to grab on to me but the man pinned his hands to his sides. The man and woman both ran to the side of the boat

"Say goodbye to your lover" the both said before jumping over broad with Percy and Nico.

I ran to the side of the boat.

"NICO!" I yelled looking down at the water. I just barely caught a glimpse of something moving away from the boat.

"Will!" I heard Annabeth yell and looked over at her to see she was lowering a rowboat into the water. I quickly ran over to help her. Once the boat was on the water Annabeth climbed down the latter on the side of the ship then got in the rowboat. I was about to follow her when I felt a hand on my shoulder. And I looked back to see Chiron standing behind me as a centaur

"Be careful, and bringing a weapon wouldn't be a bad idea" Chiron said

"What?....you?...." I said staring at him in disbelief

"Will! We need to hurry, we can ask questions later!" Annabeth hollered from the rowboat

I quickly grabbed the first weapon I saw which was a harpoon then climbed down the latter and got on to the boat

"Good luck!" I heard and both me and Annabeth froze. We know that voice but it couldn't be. I looked back at the boat to see a dragon with the grin of a mad genius that could only belong to one person
