"Oh… okay." Tank stared at the weird human before he vanished the pigeon with a click of his fingers, he nodded to Harry before popping away.
"Oh fucking hell," Harry groaned before he walked over to the bed, Hedwig flew back to her perch before Harry hopped onto the bed and lied down on his back. "Hedwig," Harry spoke up several minutes later. "do you think I should see a healer or something?" Hedwig nodded and hooted to say 'yes, I do think you should see a healer, you ate a damn pigeon'. "Fair enough." Harry sat up and covered his mouth when he yawned.
'No,' A deep voice echoed in Harry's head, causing him to stop moving. 'no healers.' Harry looked around the room but didn't see anybody but Hedwig.
"Who are you?" Harry spoke up, ignoring the way Hedwig was looking at him. "I can hear you, but I can't see you, who are you? Where are you?"
'I am inside your head,' The voice replied.
"My head?" Harry blinked, one hand instinctively going to his scar.
'No, not in your head's scar, though that scar is fairly interesting by itself.' The voice replied.
"Who are you?" Harry demanded, looking around with the hope that eventually he'd see or spot something.
'I am Venom,' The voice answered. 'and I am bonded to you.'
"What?" Harry blurted out.
'This relationship is quite beneficial to both of us,' Venom hummed. 'trust me.'
"I don't even know you!" Harry hissed. "How is this beneficial? I don't even know what or where you are!"
'I am inside of you, what I am is a 'Klyntar'.'
"A what?"
'Klyntar,' Venom repeated slowly as if talking to a small child. 'we're commonly known as a symbiote, an advanced alien species…'
"Aliens?!" Harry blinked. "Are you telling me that you're an alien?!" Harry blurted out, struggling to believe it. Magic was one thing, but aliens was a whole other ball game. Though, to be fair, he would have laughed at the idea of magic existing if asked about it a few years ago.
'Yes, now listen to me,' Venom ordered. 'despite what you may believe, this relationship benefits both of us. I need a host to survive.'
"What? You'd die without one?"
'Yes,' Venom reluctantly admitted, knowing that Harry was against needlessly causing harm to others, even those that weren't human. 'having a host keeps me alive. And I, in return, bring plenty of benefits to the table. As long as I am by your side you'll be stronger, faster and far more dangerous. Perhaps I might even have a positive effect on your magic, I've never bonded to a wizard before.'
"C… can't you just bond to someone else?" Harry asked hopefully.
'I could try,' Venom answered. 'however, doing so would risk their lives. If the host is not compatible then it's possible that they would die if I stay too long.'
"Oh…" Harry paused, not sure how to respond. "… wait, you've killed people?"
'One person, though that was accidental,' Venom replied, he quickly continued speaking when he saw that Harry looked more than ready to begin a lengthy rant. 'he was dying anyway. He was an astronaut and their ship had been in a massive crash, he barely survived and his leg was broken. If I didn't attempt to bond with him then there was every chance that he would have just died in the field by himself.'
"I… but you…"
'If I had successfully bonded to him then I would have been able to heal him,' Venom explained. 'if the bond was successful then he would have survived.'
"I… I'm sorry, but no…" Harry shook his head before standing up. "… if… if you need a host then I'll find you someone or… something… I don't know! I just want you gone!" Harry quickly walked to the door, intent on going down and asking Tom to contact someone that could help him with the fact that he apparently had an alien in his body. Harry reached for the door handle but that was about as far as he got as his entire body froze just before his fingers could wrap around the handle. "W… what's going on?!"
'You are not going to contact anyone, not yet.' Venom whispered from inside Harry's head, Harry was about to respond when suddenly his body turned around against his will and he found himself walking back to the bed despite his best efforts to do otherwise.
"Stop that! Let go of me!" Harry yelled before he threw himself on the bed, landing on his back before his body snapped into a straight position with his hands falling to his side and his legs sticking together as if he had been hit with a body bind spell. "Get off me, you stupid parasite!"
'PARASITE?!' Venom's boomed in Harry's head, causing the young wizard to wince. Harry's right arm suddenly stretched out, a second later Harry ended up slapping himself on the face, hard.
"Ow!" Harry hissed.
'Don't call me that again,' Venom growled, forcing Harry's arm back to his side. 'now listen to me, Harry. If anyone finds out about me, then I could be killed if I'm lucky, or thrown into a lab and tested on until I wish for death. And I will not allow that to happen.'
"What do you want?" Harry growled out through gritted teeth.
'You, just you,' Venom answered, not hesitating for a moment. 'that is what I want. But enough about me, because you need me a lot more than I need you.'
"What?!" Harry wasn't sure if Venom could see the look of disbelief on his face, but if he couldn't then the disbelief in his voice should get the job done. "I don't need you!"
'Don't you?' Venom asked in a slightly amused voice. 'Think about it, Harry, if I leave you then I go and find another host. I might end up accidentally killing a few potential hosts until I find the right one, perhaps I could find a truly powerful one like Albus Dumbledore, but then you would be alone. Think about it, Harry, you need help.'
"I don't need anything from you!" Harry hissed, still trying in vain to move his body.
'Then you've not been paying attention, Harry,' Venom responded. 'think about it, you spent ten years suffering at the hands of the Dursleys. All because you weren't strong enough to stop them.'
"I couldn't do anything because I was a child!" Harry argued.
'You still are by human standards,' Venom calmly replied. 'but if I was there then they wouldn't have dared raise a hand against you. Then you arrived at Hogwarts and nearly died a few times, only surviving because of stubbornness and luck. If it wasn't for your mother's sacrifice then you would be a small body in a grave and Quirrell would have gotten the stone.'
"How do you know all this?" Harry asked, his face pale.
'I am inside your head,' Venom reminded him. 'remember? All of your memories, all available to me.'
"Get out!" Harry roared, alarmed by the thought of anyone, especially an alien, accessing his mind.
