I figured that Tavvy doesn't get too much attention, as he's only seven. So, I decided to explore his future. LoS spoilers.
Eight Years Later
Octavian Blackthorn didn't know his family very well. After all, he was just seven when he was ripped away from them.
He hadn't been at the meeting of the Council, hadn't seen Anabel kill first the Inquisitor, and then his sister. Hadn't known that, as he played with the blue boy and the one that didn't speak English, things would never get back to normal.
Mayrse, the woman that was watching him, glanced out the window as Tavvy showed Max and Rafe a simple hand-clap game. Max kept getting the claps mixed up and Rafe mispronounced every word. But, that didn't matter. He was still having fun.
"Hey, boys," Maryse said, suddenly having gone still. "Let's play hide-and-seek." She turned to Rafe and said what Tavvy assumed the same words in Spanish. "I'm only counting to ten, so hurry up."
Max and Rafe sped off, but Tavvy didn't know the house very well. He liked hide-and-seek, however, though he hadn't played in a long time. The last time had been with the girls, Dru, Emma, and Livvy. Livvy always had the best hiding spots and Emma was the best at seeking. That had been before even meeting Christina. But, Tavvy ran further into the house, looking for a place to hide.
He heard the knocking on the front door, and the voices outside, but didn't hear the specific words. Something about Downworlders and Annabel and the Inquisitor. He heard Maryse yell, and knew that she was trying to send the people away, but heard fighting and knew they were inside. Tavvy knew that hiding wasn't a game, but he wondered if the other two boys realized what was happening. He didn't know where they were, but he also had to hide.
Tavvy found a room with a bed high off the ground, but the skirt fell to the floor. He easily slipped under it, and pushed himself as close to the wall as he began to shake. He knew, however, that when the skirt was flipped up, whether in a minute or an hour, it would be the smiling face of one of his siblings. Maybe Mark would slip in with him and question what he was doing. Or Julian would hold out his arms, welcoming Tavvy to come out. Possibly even Dru, who would smile and tell him it was his turn to seek.
He heard heavy footfalls enter the room. "Come out, little ones," said a voice. He recognized it, one of the Centurions. One of the ones that the others didn't like. The one with the twin brother.
A second pair of footsteps joined in the room. "Others are coming." It was the twin brother. "Those for Downworlder rights. We have to leave."
"In a moment," the woman said. Before Tavvy could react someone had reached under the bed, grabbed his wrist and pulled him out. Tavvy cried out, but no one came to rescue him. "Shut up!" the woman yelled, and then she pushed him into her brother's arms.
Tavvy tried to kick and fight, but he was small and young. They passed Maryse who was passed out on the floor, a bit of blood oozing from her head. Another Shadowhunter was leaning over her with a stele, and when the rune was finished, the bleeding slowed.
"Now," Zara said to him after he was taken to the Dearborn home, "you're really the only one that can be saved." She paced back and forth in front of him, muttering things he didn't understand while he tried not to cry. What did 'tainted' mean? Where were his siblings? Julian and Livvy and Ty and Dru and Mark?
Every time he asked, she yelled at him, harshly, that they would ruin him. And then he did cry.
A day after that, he was placed with a different family, at a different Institute, this one in Sydney, Australia. It was a whole new world, and though they spoke English, they definitely spoke funny.
The Copperhills weren't mean. They had a daughter just a year younger and boy two older, so he had others to play with. But they were strict. Up at six every morning. Bathed, beds made, and ready to eat by seven. They prayed there, and Tavvy lost a few snacks for not properly praying first.
He began training when he was nine, two years with no contact from his family. He didn't know what had happened to them. As far as he knew, they had abandoned him. However, he was a Blackthorn, and he knew that meant something. So, when he trained, he trained hard, and he quickly surpassed Ian Copperhill. Though, the two still got along very well. And when Tavvy was fourteen and Ian sixteen, they became Parabatai.
By that time, he was used to being called Octavian, and only Missy Copperhill called him Tavvy sometimes.
Octavian always kept quiet when discussing Downworlders. They all knew that he had two siblings that were half-fae, and because of that, he could never quite agree with all the beliefs of the Copperhills about the 'scurge.' He did, however, remember his near fatal encounter with a warlock.
It was just after a successful patrol when he was fifteen that he returned to the Institute with Ian to find a slightly familiar face standing in the entrance hall. He was laughing with Ian about the shock of the demon they had slayed, opened the door, and there stood a woman, short black hair and blue-green eyes. She stood tall, very much so, and Octavian could tell that she had slimmed down, though she still had more curves than the average Shadowhunter woman.
"Dru," he said and stood still.
"Tavvy!" Dru cried and came for him, wrapping her arms around him. He was just short of her height, he realized, but knew that he would soon be taller, as he still had a few years of growing to go.
"What are you doin' here?" He asked. He knew that he must sound different, having lost his LA accent years ago and picked up an Australian one.
She released him, stepping back. He could see on her face that she realized that he hadn't returned the hug.
Ian lightly elbowed him. "Been holding back on me, mate?" He asked. "You got yourself a girl?" He stepped forward and offered a hand. "Ian Copperhill," he said. "A pleasure to make your acquaintance."
"This is Dru," Octavian said, still not turning his eyes from her. "And she's not my girl, she's my sister." The last word felt weird to him. He never forgot that he had a sister. Three, in fact. But he hadn't seen Dru in eight years, and Helen even longer. He had learned, somewhere along the line, that Livvy had died. He also knew that she had died when he was seven and he hadn't learned until over a year later.
Ian's amber eyes widened. "Well then, that changes things."
"She's four years older than you," Octavian said.
"All the more gorgeous," Ian said.
"Would you stop hitting on her?" Octavian finally turned to his Parabatai.
Ian lifted his hands. "Okay, okay, I got it," he said. "I'll leave you two to it, then." With that, he walked off.
"What are you doing here?" He asked once he was sure Ian was gone.
"What do you mean, Tavvy?" Dru asked. She had looked annoyed by Ian, but concern took her features at his question. "I've come to take you home. To Blackthorn manor."
Octavian looked away. "Why would I want to go there?" He asked. "There's nothing for me there."
"We are," Dru argued, placing her hand on his shoulder. He shook it off. "What's wrong, Tavvy?"
He tried hard to hold back his tears, but his eyes were burning. "You guys abandoned me," he shouted. "I haven't gotten so much as a letter from you for eight years." She took a step back, looking shocked. "I like it here. Ian's my Parabatai and Tara and Missy..." He thought about all the others in the Enclave. Tara Clearbrook and her parents, who were always so nice and took him out on their boat on the weekends after church. There were the Snowglens, the three kids and Autumn who taught all the kids of the Enclave. And then there was Fawn Truwind, with her eyes that matched the water and the silky brown hair. If he left, how would he tell her his feelings.
"Tavvy," Dru argued gently. "We didn't abandon you. They separated us. Ty and Kit and I were thrown in the Academy. Julian got slammed for what happened. Cristina was ordered to go back to Mexico. Emma and Mark were both exiled. We've only just been able to reclaim the Manor, though Mark is stuck in England and not allowed to be more than two kilometers from the Blackthorn Manor there. We wanted to come for you, but they wouldn't tell us where you were. Jia Penhallow used every connection she still had after being voted out of Consul to find you for us."
"Well, it was a poor use of her connections," Octavian said. "It's been a long night, I'm going to bed." He stalked past her toward the stairs. He was aware as Dru followed him up the spiral staircase for three flights, though she didn't talk.
"You can go now," Octavian said when he got to his floor.
"I'm not leaving without you," she said.
He growled a bit. "The only one of you that has a real excuse of not seeing me for the last eight years is Livvy," he snapped. He knew it was a slap in her face, she had seen Livvy die. But, he didn't care. He also knew it wasn't true. If Mark had been under an essential house arrest and Dru and Ty at the Academy, they wouldn't have had an easy time coming for him. He assumed that Helen was still at Wrangel Island, and he could only imagine what Julian had been through.
In the months after the fateful day Octavian had been taken away, the Cohort had gotten a lot more power. The new Consul was neutral, but the Downworlders had been constricted. There was a registry, but only for Warlocks, as it was impossible to track down every vampire, werewolf or fairy. The Seelie Court and Unseelie Court declared war on one another, little of which had spilt into the mortal world, but it had reduced the fairy population by at least a third.
However, hunting Downworlders suspected of unlawful activity was open game. Ian and Missy spied on werewolves and vampires all the time waiting for one to break a law, something that Octavian avoided. He had once had to kill a vampire, but the idiot had decided that a park was a great place to find fresh blood and had nearly killed an unwilling victim.
He didn't slam his door. That would only get his a hard slap across his back with a paddle, which he had a few scars from the past. It wasn't a punishment reserved for him. Ian had been slapped with the paddle more times than Octavian could count, for more offenses than Octavian knew existed. Slamming a door was just one of them. However, he did lock the door, which he wasn't supposed to do.
Once alone, he shucked off his gear and looked at himself in the mirror. It had been eight years since he had seen a sibling, but his memories were rushing back to him. He studied his eyes, the same color as most of his siblings. He recalled that Ty had grey eyes, but his were the Blackthorn blue-green. He also had dark hair that fell in curls, though he usually kept it cut short. He had grown strong since he had been in Sydney. But, thinking about his family, looking in the mirror, he realized that Dru would never have mistaken him for anyone but who he was. He looked just like Julian at age fifteen.
It took him a few minutes to tear his eyes from the mirror and get to bed.
