When We Stand Together

Chapter 01: Reason to Stay

Starling City, 2012

Thea Queen ran down the stairs of the home that she lived in with her mother and step-father, since her older sister had moved out of home, her father had died and her brother was presumed dead. She was considerably excited upon seeing Oliver walk through the door. Almost as soon as she and ran down the stairs and into his arms; she was running back up the stairs to call their sister. Oliver followed Thea up the stairs and stopped short of Thea's bedroom and listened to what his younger sibling was doing.

"Hey Lia, you have to come home now," Thea said, this confused Oliver, he was wondering why he hadn't seen their older sister. "You don't understand, Ollie...he's back,"

'Thea? You're not messing with me are you?' Thalia questioned, sitting down on her couch and turning her laptop on.

"I'm not, mom brought him home just now," Thea said quietly as she realised that Oliver had followed her up the stairs. "Ollie, I know you're there," Thea opened her bedroom door, and pulled her older brother in.

'Thea, put him on I want to hear his voice,' Thalia spoke quietly as footage from Oliver's return flooded her laptop screen. 'Please?'

Thea tried to hand her phone to Oliver bit he just brushed it off. Thea and Thalia both sighed, Thalia muttering that Thea should put her on speaker, the younger Queen doing just that

'Ollie, believe it or not you're not alone,' Thalia said, she didn't know how else to get her baby brother to talk to her.

"Thalia, you can't tell him over the phone – mom will hear!" Thea hissed, she didn't want their mother hearing her. "Ollie talk to her, please,"

Oliver reluctantly took the phone from Thea who had taken it off speaker as she handed it to him. There were some things that their mother had neglected to tell Oliver and Thea when they were children about their sister. Thea had only found out after over-hearing Thalia arguing with their mother.

"You don't know anything Thalia," Oliver was adamant that his sister couldn't know what he was going through.

'Don't pull that bullshit on me Oliver Jonas Queen, you're the one that doesn't know anything,' Thalia hissed at him, pausing before she continued. 'I'll be home soon, and then we'll talk properly,'

"You don't know any of what I'm going through, you can't possibly know," Oliver told her as he stared at Thea who shrugged.

'Have you ever thought that you might possibly be the one that doesn't know anything,' Thalia took a deep breath before she continued. 'Didn't you ever think there was something missing for your memory when we were children?'

"What are you talking about?" Oliver muttered, as he could hear Thalia typing on the other end of the phone. "Thea, what's she talking about?"

"She told you that she'll talk when she's home," Thea sighed, she wasn't sure that she should have gotten hold of Thalia.

'Give the phone back to Thea, I have things to clean up here and then I'll be back,' Thalia told him, Thea could hear what Thalia was telling him so she quickly took her phone back. 'Hey, kiddo, I'll be home in the next few days. I have a couple of things that I need to clean up here first,' Thalia and Thea hung up their respective phones while Oliver walked from Thea's room and headed towards his bedroom.

A week went past and Oliver continued to cause havoc for everyone around him while dressed as the Hood. Thalia arrived back in Star City, just in time to see her brother get in yet another fight, this time she stopped him – without warning.

"Sorry, Ollie but this is for your own good," Thalia sighed, knocking him out and being grabbed by John Diggle at the same time.

"Sorry, Miss but you'll have to come with me," John said as Thea ran up to Thalia and wrapped her arms around her older sister.

"Thalia! How did you know Ollie would be here?" Thea asked hugging her tightly, Thalia reciprocated the hug.

"Hey T, who's the muscle?" Thalia asked, motioning to John as the older man bent down and helped Oliver up. "I'm Thalia Queen, and I'm betting that my mother never told you she had three children,"

"This is John Diggle, he's Ollie's bodyguard," Thea told her, her arms not moving from around her sister.

"He's going to have a lovely black eye later," Thalia grinned, pausing before she told them that they should probably go home to which John and Thea agreed. "Thea, please tell me you haven't been getting drunk and disorderly,"

"Can't tell you that..." Thea trailed off knowing that she had disappointed her big sister.

"T, you promised me last time I found you like this," Thalia sighed, as they all made their way out of the club.

Thalia, Thea and John loaded Oliver into the back of the car town-car, where Thalia told their driver to head to a house that their mother didn't know about. The only people who knew the house existed where Thalia and Thea. Thalia had purchased the house without her family knowing about it and had shown Thea the day she turned fifteen. Thalia told John to put Oliver on the couch before she spoke again.

"Mr Diggle, could you give us a few minutes?" Thalia requested as Oliver came too moving to sit up and stopping as his head started throbbing. "Please?"

"Thalia what the hell did you do to me?" Oliver questioned, before he found Thalia's arms wrapped around him.

"I may have knocked you unconscious...Look Ollie there are things that you don't know about what happened..." Thalia bit her lip as she spoke and looked between both Oliver and Thea.

"Don't Ollie me, what happened when?" Oliver questioned, now it was his turn to look between his sisters when he saw the look that they had shared.

"You blocked it out, Ollie and mom refused to talk about it," Thalia paused running a hand through her hair before she continued talking. "Do you have any idea why she refused? She wanted it to go away, she wanted the fact that her daughter was abducted, tortured and held hostage for two years..."

"You were what?" Oliver questioned, he was beginning to think that his sister was lying to him.

"Abducted, tortured and held hostage Oliver, that's why I was gone for two years when I was fifteen and you didn't see me until I was seventeen..." Thalia took a deep breath before she continued, with Oliver now staring at her with an almost vacant look. "Do you know what got me through all of that? You and Thea. Ollie I let Thea in because she heard mom and I arguing in the kitchen after you were thought to be dead,"

Thea made a coughing sound as John stuck his head around the corner of the door frame. Oliver shook his head looking at the older man as he did so. Thea had seen some of Thalia's scars and some of Oliver's, but she hadn't seen all of them and didn't think she ever would.

"Hey T, call mom and tell her that you and Ollie aren't coming home tonight," Thalia said, knowing that the seventeen would be able to come up with something to throw their mother off.

"Lia, but I never get to hear all the good stuff!" Thea exclaimed, and then huffed out into the kitchen to make the phone call.

"Thea tells me that you're not letting anyone in, I know how hard it is," Thalia told him, taking off her jacket to reveal a star shaped scar on one shoulder, and larger scar that spanned the length of her torso. "I told you, you're not alone Ollie and never will be,"

"Where did that come from?" Oliver questioned, reaching out to touch the scar that he could see on her shoulder.

"That one is from being shot point-blank in the first month of being abducted, and this one across my back they used a sharp knife and slashed my back," Thalia took a deep breath she couldn't work out how to tell him what they were after. "Ollie I was fifteen, I barely survived and you know what I still don't know what they wanted...I gave them enough bull shit to keep myself alive,"

"Why didn't you tell me?" Oliver questioned, they had always been close, him, Thalia and Thea.

"Ollie, I wanted to, trust me I really did. But mom made me swear that I wouldn't say anything," Thalia told him, before pulling his shirt from his shoulder. "Now your turn tell me how you got these,"

"One step at a time Lia," Oliver pulled away from her and pulled his shirt back covering the scars.

"Oliver, I've told you two of my scars, they're the same two that I told Thea about...there are so many more that you don't know. So now tell me that its not time, I know you have nightmares and guess what so do I," Thalia sighed, she knew that she could some how get through to her brother she just wasn't entirely sure.

"Lia, don't pretend you know anything about me, you weren't the one that was alone for 5 years," Oliver told her gruffly as he stared at his older sister.

"Mister Diggle, I would advise you stay out the room – Oliver isn't going anywhere tonight," Thalia could sense that the older man was about to walk into the room that they were sitting in. "I know you heard what I said to Oliver,"

"Ma'am, I need to talk to your brother," John insisted, but not moving from the other side of the door.

Thalia stood her ground and refused to let John in the room and refused to let Oliver leave her sight. He tried to leave out the window but found that Thalia wasn't kidding when she said that he wasn't going anywhere that night. Oliver grumbled he couldn't remember the last time someone kept this close an eye on him without him finding a way out.

"Ollie, this is my house, you won't be finding an easy way out," Thalia said from the opposite side of the door as she pushed it open. "Take my hand and come with me, Thea's waiting for us in the living room. But first I need to show you something," Thalia held her hand out for her younger brother who took it still wondering what he was doing there.

"Thalia, you may be the big sister in this situation but I don't need protecting," Oliver told her, taking her hand at the same time before she guided him to a room that she wanted to show him.

"We all need protecting, even when we think we don't," she told him, taking hold of her bedroom doors handle and pushing it open. "Tell me what's missing from the picture and then tell me that I wouldn't understand," Thalia let go of his hand and let him look around.

"You have no bed in here, why?" Oliver questioned, as he surveyed the room before his eyes landed on a pillow and blanket beside the wall.

"You know why Oliver," was all Thalia replied with putting her hand on Oliver's shoulder. "Now will you let me in?"

"My shoulder – is from an arrow," was all Oliver said as he pulled Thalia's hand from his shoulder. "Lia, this one was from being...tortured..." Oliver trailed off he couldn't tell his sister that he knew what she went through. He showed her the multiple stab wounds on his stomach.

"Ollie, tortured? But how?" Thalia grabbed his arm and forced him to look at her. "Look at me Oliver, what ever happened it wasn't your fault," Oliver was silent, he didn't think that he would ever be able to tell her fully and she didn't think she could tell him the full story either.

Oliver and Thalia walked back to Thea and the three of them sat on the lounge, Thalia putting in a movie that she knew they hadn't watched in a long time. They needed some family bonding time and Thalia figured this was the only way for that to happen.

"Lia, tell me again about the scar on your shoulder?" Thea asked, resting her head on her sisters shoulder as Thalia rested her head on top of her head.

"That's from being shot point-blank, it went right through...they always had a doctor on hand which I thought was strange," Thalia said glancing at Oliver as she spoke and then kissing the top of Thea's head. "T, how about another time, lets just watch the movie yeah?"

"Fine, but I never get all the good stuff," Thea sighed, still resting her head on Thalia's shoulder as they both felt Oliver suddenly relax. "Ollie promise us you'll stay all night," Thea glanced at Oliver and noticed that he was doing exactly what she was doing to Thalia.

"I can't," was all Oliver muttered, closing his eyes for a split second before opening them to watch the movie.

After the movie was over, Thea was all but asleep on Thalia's shoulder and Oliver had moved slightly to be resting on the arm of the couch. Thalia smiled at both of her siblings, before nudging Thea and ushering her off to bed. Thea grumbled something before going to the bedroom that she and Thalia had set up for her.

"Come on Ollie, you're in my room tonight," Thalia stood up, pulling her younger brother with her and dragging him towards her bedroom. "Pick somewhere and don't be surprised if you see me staring out the window in the middle of the night,"

Oliver took some of the pillows from the floor and moved towards the wall opposite to where Thalia had decided was her place to sleep. Thalia switched the light off, much to Oliver's surprise there was a small night-light on the floor near where he had chosen. Oliver slowly got up when he thought that Thalia was asleep and made for the door.

"Light sleeper remember Ollie, lie down and try and get some sleep," Thalia didn't move from where she was lying with her eyes close facing the window. Oliver grumbled at her and reluctantly lay back down.

Midway through the night Thalia found herself sitting shaking staring out the window in the pitch black. Oliver found himself jolted awake, sweating and looking frantically around the room before his eyes landed on his sister's silhouette. Oliver crawled over to where Thalia was sitting and went to put his arms around her but found himself being pushed backwards.

"Thalia..." Oliver was quiet as he said her name, waiting to see if she would turn around.

"Oliver, why do bad things happen to good people?" Thalia didn't turn around she spoke, still shaking as she spoke in the dark.

"Lia..."Oliver crawled back over to her and wrapped his arms around her tightly pulling her into a hug. "Let me be the one to save you every once in a while,"

"Ollie," Thalia rested her head on his shoulder as he started muttering about some of the things that had happened to him.
