Well this sucks. I thought. My name is percy Winchester and I am looking for my only family left. I am on a bus headed for Bobby Singers house. He's an old family friend that I trust. When I got there I rang the doorbell. Bobby answered. "Can I help you sir." He said. Bobby it's me Percy." I said. "Percy is that really you." "Yes Bobby it is and just to prove it." I poured rock salt on my arm. I guess you know said Bobby. "I do Bobby I do" I said. Can you call Dean here I said. "What about Sam."said Bobby. "Who is Sam." I asked. "He's your brother." Bobby said. "I have another brother?" I said. "Yes you do." he said. "Please call them."I pleaded. "Ok."He said.
Dean pov
We just got to Bobby's house and it sounded important. We got there and walked in. There was a guy in there about the same age as me in there. The guy got up and hugged me and said" my god Dean it's really you." I said "Who are you." "He's your brother." said Bobby. My brother I said. The guy said" My name is Percy Winchester. Why are you here now I said. Dean you and Sam know Greek gods are real right. Yea me and Sam said in unison. Well I am a former demigod a son of Poseidon Percy said. Sam said what do you mean former. Well there is this camp for demigods called camp half blood he explained. He told them of his adventures from when he was twelve to Gaia.
This will be percy speaking
Then one day a kid showed up on a hill. He was fighting a hellhound. I killed it and he took my sword and pushed me over. He told everyone he killed it and they all believed him. Then one by one my friends left me except my two cousins. my father disowned me after my girlfriend cheated on me with my brother Corbin Mathews and and I knocked him out. I was banned from camp.
Back to normal
"Then why show up now ."I said. "I needed to know you were safe because I was sent away about three years after you were born for the families and my protection because monsters are attracted to demigods and after this I will leave you guys alone ." Sam asked "why would you leave." Percy said "I don't want to come into your lives now." "Well I for one want you to come with us." Said Sam. "Me to." said I. "My scent would attract monsters and would put you both in danger. "Percy said. "That is just another day at the office." I said. "I actually have an Idea." Percy said. "What is that." Bobby asked. "I will call Lady Hecate and do ask two things." He said. "Ok they said. After He prayed to Hecate and got my scent removed and the other thing or whatever mojo he did he walked back in He said "I got the scent removed and Bobby stand up." I can't I'm in a wheel chair." He said. "That was the other favor." Percy said. Bobby stood up. "Holy crap." Me and Sam said. "I just talked to the goddess of witchcraft you know and the only reason she did this was because after both wars I asked my uncle for more respect to the minor gods and their children." I said. "Ok then." Sam said. After an hour of catching up they left for the road.
Three years later
Percy pov
We had just got done taking out a ghost that was killing people in an office building and were heading back to the hotel. Me and Dean fell asleep while Sam was looking for a case or demon omens.
Sam pov
I was looking for cases online when a knock came from the door. I answered and a man with the same eye color as my brother. He said "I need to speak to Percy Winchester." I said "I don't know who that is." He said "I know who you all are" I said "Your Poseidon aren't you." "Yes." he said. I pulled Ruby'se knife out and stabbed Poseidon in the shoulder and he screamed in pain and Percy and Dean woke up. "Sam stop." Percy said. I pulled the knife out. "What do you want Poseidon." Percy said. He said " Son another war is coming and monsters from other mythologies are helping Kronos." "I'm not your son you disowned me and I'll think about it." "Ok son." he said and flashed away. Percy turned around and looked at us. Dean said"Your not seriously thinking about it." "Sadly I have to." Percy said. "Why." Said Sam. "There are some people that that didn't betray me and some that care for me and one acted like a mother to me." Dean said" Those people are?" I said "My two cousins , Uncle Hades , cousins Apollo and Artemis , and Aunt Hestia but none of them could even go near me because of the laws and my banishment." "I will come with you"Dean and. He said "Thank you guys you are best brothers ever." Percy said.
