Disclaimer from previous chapter is still in account. so Harry potter not mine, the PET idea, nothing more, was inspired by the story Heroes and Ghosts found Sapayne dot com

Harry: He's grumpy right now. He hasn't had his sleep.

Cassiel: SLEEP? I DO NOT SLEEP.

Harry: I wasn't talking about you Cassi.

Koji: Yes father we were speaking of Master Josiah

Shaira: yeah him and all. HAHAHA. i'm hyper.

Artea: Shaira behave. Review please even though master is cranky. it will cheer him up. now please enjoy and do tell me what you think.

Cassiel

"Sir, we did everything we could but he didn't make it. I'm sorry." Severus felt his heart shatter at those words: "Are you sure you did everything you could?" The doctor nodded and walked over: "I'm sorry Severus, we really did do everything. He was shot too many times." Severus nodded and looked up at Josiah before he was led to the room where Harry's lifeless body resided. He had killed Voldemort but was brought down by a man with a gun. Severus continued to hum and refused to allow anyone near his beloved as he sobbed. "Harry, I'm doing what you asked me to, I'm humming. Please, I need this to work." Josiah walked into the room and looked at Severus with a mixture of sorrow and pity in his eyes: "Severus, no matter what you do, even if he comes back to life, his brain was deprived of oxygen for too long, he won't be responsive. Please let it go." Severus held on to Harry's hand and continued to hum as though he hadn't heard a thing. Draco and Ron walked into the room and began humming along with Severus who looked at them and smiled faintly before looking back at his beloved who looked fast asleep. Remus and Sirius walked in and Sirius grabbed Harry's left hand and they all began humming Harry's favorite song. Chad walked into the room a moment later and started singing the song they were all humming.

Soon Severus felt Harry's hand twitch. He looked up with a smile and saw Harry's eyes opening slowly. But instead of the beautiful green Severus was used to seeing, they were now pitch black flashing red. "NO, Cassiel, calm down." Severus said telling everyone to move away from the body. Harry had told Severus long ago, even before they had become close, who Cassiel was. He hadn't wanted to at first, but was forced once Severus saw the memory of the day Harry allowed a bodiless Demon share his body to live. "Cassiel, please calm down." Severus said, tears falling from his eyes at the realization that his Harry would never return.

Harry sat up and glared at everyone in the room. His eyes were burning red now and his teeth were growing. His face became pale and his hair started growing. The scar came back full force and began to bleed but no one dared walk up to the enraged demon. "WHO KILLED HIM?" The demon asked standing up and glaring at everyone in the room. "We don't know, please Cassiel, you don't have to do this. Just calm down and we can find him. Please." Severus pleaded with the demon and it seemed the pleading worked for the demon calmed considerably and sat on the bed. "He was the only one to give me a second chance. I was supposed to protect him but I didn't." Harry, or rather Cassiel said looking at everyone in the room.

"So who are you?" Draco asked walking up and wiping the blood off the demon's head. Cassiel sighed and shook his head: "My name is Cassiel. I was banished one hundred years after my mate. I was wandering the earth when I came upon Harry. He was seven at the time so it was very easy to convince him to let me share his body. I told him if ever he should die I would take over his body and get revenge on anyone who had ever hurt him. He smiled at that and we used to hold conversations about how to kill his "family" once he was old enough to leave the house. We had a lot of good laughs because of that. But I also knew a loophole for his death. If he was pregnant at the time, his soul and memories would be transferred into the growing baby and he would be reborn.

"He told me about three weeks ago, if ever this should happen, I should grant you eternal youth and life Severus. He will be born a half demon now and he will have the eternal youth and life you do not have. He can't bare to lose you. He does love you very much Severus and if you love him, you will accept this offer." Severus nodded, not even hesitating one bit. "Good. I'll start the ritual in three days, till then I'm going to have to finish my transformation and gather my demons. I have a lot of unfinished business to attend to." Everyone nodded looking at the demon. At least they were going to get their Harry back but what about this demon. Was he trustworthy?

Severus walked up and thanked the demon before walking from the room. "He loved Harry. You don't know how happy he is to hear he'll have his love back." Chad said walking up and looking at the demon that's face was beginning to change. His eyes went back to pitch black before they turned their natural color, golden white. His hair continued to grow until it reached the middle of his back, and his body seemed to fill out and grow. This wasn't Harry, this was Cassiel. "I'm sorry, I know you wanted to see Harry. I know you all miss him, hell I miss him, but you just have to remember he'll be back." Chad nodded and walked from the room. Draco and Ron walked up next and looked at the demon: "You really cared for him didn't you?" Draco asked holding Ron's crying form to him. "Yes I did. He was like the son I lost when I was very young. He had the same personality and the same love for life." Draco nodded and led Ron from the room.

Remus and Sirius were next. Sirius was sobbing but he managed a question: "Are you sure Harry'll come back?" The demon nodded knowing what they wanted. They wanted to be with Harry for as long as inhumanly possible. "I'll do the ritual for all of you. You are all his friends and deserve to live side by side with him till the end." Remus nodded and asked his question: "why did you want to help Harry?" Cassiel looked to the ground as a tear left his eye: "He was the only human who took pity on me and allowed me to live. He was the only one who cared and trusted me no matter what my past was like." Remus nodded and extended his hand: "I believe Harry would want you to live with the rest of us. Come. We're going home." Cassiel nodded and looked at Josiah who seemed to be speechless: "Are you coming or not?" He asked the confused doctor. Josiah shook his head and walked from the room. Cassiel smiled sadly and walked out the room followed closely by Remus and Sirius.

The walk to the house was done in silence, no one seemed to want to believe Harry was dead. "As I said, he'll be back..." before Cassiel was able to finish his sentence a voice interrupted him. DAD. Cassiel turned and looked at the boy running towards him. He had red and yellow hair tied up in a ponytail, black eyes and a tall well built body. "Shaira." Cassiel said walking up and hugging his son. What are you doing here? Shaira smiled sadly: it's about father. Tomo wants to kill him. Cassiel was seeing red now. What about your grandfather, how much longer? Shaira thought a bit before answering: Give or take three more years. He's very weak now so it shouldn't take too long. Tomo's coming here to finish you off but he doesn't know you're as strong now as you were before you were banished.

Tomo killed Harry didn't he? Shaira nodded: yeah, he possessed a homeless guy and had him shoot Harry to death. He knew you were in his body but he didn't know you wouldn't die Severus growled: so it WAS your fault he died. You're lucky he'll come back or I would find a way to kill you Cassiel looked speechless before he remembered Severus knew Latin. Trust me I would kill myself right now if Harry wasn't able to come back to life. Severus walked away towards the house, no one bothering to stop him. Shaira, I'm going to go talk to him, you stay here with everyone and keep them safe. Bring them to the house in one hour. We can catch up later. Shaira nodded and led everyone away from his father.

"Severus, you have to stop this, I'll do the ritual, and my pregnancy won't take as long as a human's. Don't kill yourself over something like this. You'll have your love back I promise." Severus glared at the other man and said with venom in every word: "You have NO idea what I'm going through so quit this 'I understand' shit." Cassiel glared at the man before him before starting his story.

"When I was 17 I fell in love with my step brother. He and I loved each other more than you could possibly imagine. We had two kids together. Anyway, his father wanted him to marry a girl named Sinning, and so finding no way out we decided one of us should get pregnant to keep this from happening. It turned out to be Artea who got pregnant. He was ecstatic. We were going to have a baby. His dad was furious though, had him give up the baby the moment he was born. I took the baby and named him Koji, knowing Artea would love the name. He was forced to marry the idiotic woman anyway. Since we were only half breeds, half elf and half demon, he couldn't marry a full demon so Sannina was the only one father could come up with who'd want to marry Artea.

"One day after the wedding, I went over to Artea and had him watch the baby for a bit. When I knocked Sannina opened the door and was very happy to see the baby saying she'd give the baby to Artea when he got out of the shower. I nodded and left. The only think I remember after that is a horrific scream and Sannina being thrown from the house. Sannina was banished but Artea wanted her dead. She had, after all, eaten our child. I agreed to start a war to get the wench unbanished so Artea could kill her. In the end Tomo told father where we were and Artea was caught. He was banished and I had to stand there watching. Shaira was born months after and with his help I was able to make it so Artea's soul would wander from body to body on earth so he wouldn't be tortured. I would go and see him everyday, trying to find a way to get him unbanished, to see him again, but it never worked, I was always hurt. My heart broke more and more everyday until I finally did the unthinkable, I killed my mother and I was too banished. Shaira performed the ritual and sent my soul in search of Artea's. That's when I found Harry. So you see, I do understand what you're going through. I've lived through 100 years of it." Severus looked over at the demon before breaking down and crying: "Cassiel, he was a young boy. He had his entire life ahead of him, why did Tomo do this?"

Cassiel held the sobbing man and sighed: "I don't know but trust me he will die. You don't have to worry. Once he's dead Harry will live a good life, one full of happiness." Severus smiled sadly and walked into the house to make some of Harry's favorite tea. "Do you want anything to drink?" Cassiel nodded and sat at the table. "Yes, fire whiskey would be nice, but I have Harry to care for right now so I'll settle for some tea." Severus nodded and made tea for the two of them: "I'm sorry Cassiel. The last time we met I was under a lot of stress."

FLASHBACK

"Mr. Potter, Calm down." Snape said walking over to the upset boy. "Mr. Potter isn't in right now." Harry said in a voice that wasn't his own. "Your foolishness made him call on me SEVERUS." With that Cassiel charged at Severus, grabbing him and throwing him into a near by wall. "YOU WILL NOT UPSET HARRY. LEARN TO CARE FOR HIM OR YOU WILL DIE." With that Harry fell to the floor.

"Professor Snape?" He called finally standing up and walking towards his professor. "I'm sorry. When I hum Cassiel comes out and he gets mad. He's my bodyguard. He protects me and I give him a place to live until he finds his mate." Snape stood and looked at Harry: "So that was Cassiel. Well, tell him to keep his temper. I don't want him killing someone when he's Mad." and with that Snape walked from his classroom not even looking back at Harry who had fallen to his knees and started crying.

END FLASHBACK

"Not to worry Severus. It wasn't your fault I was in a bad mood. You really hurt Harry. He doesn't hum unless he's really pissed off or sad." Severus thought about it a bit and realized he had been a little harsh on the boy. "I did ask for forgiveness later on that day so I do believe he forgave me or you would have killed me by now. Why didn't you come to his aid when he was turned into a pet?" Cassiel looked down at his cup of tea before answering: "They locked me in his mind when they did that to him, I tried to fight my way out but it didn't work. I was stuck." Severus nodded and looked at Cassiel's stomach. "Will he be okay?" He said nodding towards Cassiel's stomach. Cassiel smiled and nodded. There was no way in hell he was going to let anything happen to Harry. "You're face is changing." Severus said looking up from his cup of tea and smiling. "Yeah, my bone structure will change until I start to look like myself again. Give it three days and I should look like me again." Severus nodded and took a sip of his tea. "I'm going to miss him so much. And to see him and not be able to touch him, it's going to be worse. I don't want him to think of me as an uncle, or his father's friend, I want him to know me as me." Cassiel smiled sadly: "I know, but don't worry, he's going to have all his memories and he'll remember you for who you are to him not who you're going to be. All you have to do is wait." Severus nodded and continued drinking his tea.

"It's time for your ritual Severus. Everyone else went through it, even Chad." Severus looked up at his friends who looked like a younger version of themselves. He nodded and walked from his room, letting go of Harry's pillow at last. "Let's do this." He said walking passed Draco and Ron, who both had big grins on their faces from being turned into a half demon along with everyone else. Draco and Harry were the only one's who looked remotely different. Ron's nose shrunk a bit, his eyes turned black and his hair darkened while Draco's eyes became a golden color and his hair had streaks of black in it. Severus sighed and walked to the living room where everything was already set up. There were three healers as well just incase. "Okay Severus lie down in the circle." Shaira said walking up to him and leading him to the circle in the middle of the room. Severus did as he was told before taking a deep frightened breath. "Start the ritual Dad." Cassiel nodded and began, pouring what felt like ice cold water on his face. With a murmured incantation the entire room began to glow. Once the glow was gone Severus looked up to see Shaira cutting his own wrist and pouring the blood on his mouth: "Drink it Severus." Severus nodded and drank the blood given to him. He licked his lips and when the blood was gone he felt his body change. He felt his nose become straight again, to the way it used to look before he broke it at a young age, he felt himself shortening just a bit and his hair growing in length as well. Once the transformation was complete he stood and looked at himself in the mirror, indeed. He looked as he had 18 years ago when he had been no more than 17. "Holy shit." Cassiel smiled softly and banished the demons who were no longer needed.

"So what do you think Severus?" Severus was speechless so instead he smiled to show his gratitude. "Looking good uncle Sev." Severus smiled a bit and sat at the table. "Thank you. I feel so much better. I don't even have my dark mark anymore." Cassiel nodded and had Shaira sit as well. "Dad I learned from someone in the underworld that Koji isn't dead. Lucifer found him and has been raising him ever since. I don't know why he didn't tell you anything but when I went to see him, he seemed extremely happy to see me. Knew I was his brother." Cassiel though about it a bit and smiled: "He remembers what we smell like, after all these years., go get him." Shaira looked down at that: "I can't. Lucifer won't allow it. Something about waiting till father is unbanished." Cassiel nodded, saddened that he was not able to see his love just yet.

"Well, well, well. If it isn't my idiotic step brother. I can't believe father adopted your sorry ass." the ugliest demon anyone had ever seen, said walking up to the group. Everyone stood and took their attack stance: "What do you want you filthy beast?" Chad asked raising his wand and pointing it straight at the demon. "This is between me and my 'brother'. Cassiel, I challenge you to a one on one fight, whoever wins gets to have one wish fulfilled." Cassiel thought about it, and nodding his head, he got up and walked over to his brother. "I'll accept your challenge. Two months from now right here in the front yard, no one interferes." The other demon thought about it and shook his head. "No, two years from now in your front yard." Cassiel laughed: "What, Tomo, are you afraid of me even now?" Tomo shook his head and laughed: "ME, afraid of you? Get real, two years is barely even a day in hell. I'm giving your son time to grow up so he can see me kill you." Cassiel glared at his brother and held a hand over his stomach protectively. "Fine, you've got a deal." And with that Cassiel sat back down and pretended no one was around him. "No worries little one, I'll be just fine, you won't ever lose me like my son's did." Shaira looked at his dad and sighed. This was going to be a trying two years for Cassiel. "Dad, are you sure you want to do this?" Cassiel nodded and held onto his stomach as though his life depended on it. "Yes, I want to finish this. He killed Harry and he should die."

R&R people, it's good for my imagination. :D
