They're twins in this one

You worked for Team Arrow and you heard Roy's phone ringing, you and Roy were pretty close so you were gonna answer it for him, when he came over and took the phone out of your hand. He declined the call and you tilted your head at him. "Who's Jackson?" You asked with a smile. He smirked back at you. "You know, you really shouldn't go through people's stuff Y/N. It's rude." He teased.
"Why're you dodging the question Harper?" You asked with a smirk. He sighs. "Okay, I'll tell you. But you have to promise not to tell anyone else about this, okay?" You smile and nod. "Okay I promise." "Jackson..is my twin brother.." Your eyes widen and your mouth falls open. "What?! There's two of you?! How come you've never mentioned this before?" You exclaim. "Be quiet! I've never mentioned it because, we don't get along very well..he's a total douche bag. He's a spoiled rich kid bully, he's absolutely nothing like me! And, Felicity and Oliver can not find out about this okay?"
"Find out about what?" Oliver asks as him and Felicity walk into the room. "Yeah, find out about what? Oh! Are you two finally dating?" Felicity asks. It was no secret that she wanted you guys together, but it was still embarrassing. You and Roy started to blush. "What? No!" Roy says as he shakes his head and tries to hide his face. "Then what are you guys talking about?" Oliver asks as he crosses his arms.
"Oh, Roy was just telling me that he has a twin brother." You say with a smile. "Y/N! You said you wouldn't tell anyone!" Roy exclaims. "Yeah, I know but I just couldn't keep it in! Why can't we meet him?" You ask. "And why didn't you tell us?" Oliver asks. Roy starts to look angry. "You wanna know why I didn't tell you? Once you meet him, you'll find out!" You and Felicity smile. "So..wait, does this mean we get to meet him?" You ask. He smirks at you. "Careful what you wish for Y/N. We're gonna take a trip to Beacon Hills.
Beacon Hills was a small town in California, you'd never been there before, but you were super excited to meet Roy's brother. It still didn't make sense why he didn't tell you about Jackson, you guys told each other everything. Jackson couldn't be that bad, could he?
When you arrived at Jackson's house Roy still looked kind of nervous. He knocked on the door and a guy who looked almost exactly like him answered it. Your eyes widened and your jaw dropped. "Holy crap it's real." Oliver said behind you. "Yeah, I honestly thought you were lying." Felicity adds. Jackson looks kind of confused. "What are you doing here exactly?" "My friends wanted to meet you." Roy replied. "So you came all the way here because your friends wanted to meet me?" Jackson asks as he rolls his eyes. "They can be very persistent.." Jackson turns his head to you and smirks. "Well, I guess I don't mind too much, you should have introduced them to me a lot sooner."
He holds his hand out for you to shake it. "My name's Jackson. Remember that, you'll need to know it for later." He says with a wink as you shake his hand. You can't help but laugh. "I'm Y/N.." He doesn't introduce himself to Felicity and Oliver, but he motions for all of you guys to come inside. "Well isn't he a delight?" Oliver mumbles sarcastically as he walks inside. "Still happy you get to meet him?" Roy whispers to you with a smirk.
You shrug and smile. "I think he's kinda cute actually." His smirk fades and he starts to look confused. "What? We look exactly alike!" He whisper screams. "Oh please Roy, there's no doubt that I'm way better looking than you." Jackson says with a smirk before winking at you again. You blush whenever you realize that he must've heard you. Roy clenches his jaw and rolls his eyes, he looked kinda jealous actually. But that wasn't possible, was it?

"So, when are we leaving?" Oliver asked as he leaned up against Jackson's Porsche. Roy shrugged and put his hands in his pockets. "As soon as possible I hope." Jackson came outside and furrowed his eyebrows. "What do you're doing?" He asked Oliver with an annoyed tone in his voice.
"What..?" Oliver replies. Jackson rolls his eyes and pushes Oliver off of the Porsche. "Don't ever touch my car." Jackson smirks. Oliver rolls his eyes. "Yes, as soon as possible would be nice." He mumbles to Roy before walking inside. "So, I wanted to ask you a question." Jackson states before using a rag to clean off his car door. "What?"
"I wanted to ask you about Y/N-" Roy cuts him off. "Why do you wanna know about Y/N?" "Because maybe I wanted to ask her out, why do you care so much?" Roy stays silent and looks down at the ground. Jackson looks at him and smirks as he crosses his arms. "Unless...You like (her/him) don't you?" Roy clenches his jaw. "Just stay away, okay?" He replies before walking inside.

Jackson offered to show you around Beacon Hills, and of course Roy wanted to go with you guys. He invited you to go to some girl named Lydia's house because she was having a party, you weren't sure that a stranger would want you at her house, but Jackson assured you that it was fine.
When you entered the house a girl with bright red hair came over and smiled at you, but then she noticed Roy. Her eyes flashed back and forth between Roy and Jackson. "Can someone explain to me what's going on?" She asked. Before anyone could answer two guys walked over and their eyes widened. Jackson rolled his eyes. "This is my twin brother Roy, and this is Y/N." "What?! There's two of you?" One of the guys said with a disappointed look on his face. "Shut up Stilinski, I'm one of a kind. And obviously the better looking twin. Roy is basically just a cheap copy and paste." Jackson replies with a smirk.
The other guy rolls his eyes and laughs. "Hey, I'm Scott. And this is my friend Stiles." The red headed girl smiles. "And I'm Lydia." You smile and shake her hand before walking inside. "I'm Y/N, and this is Roy." You reply. "So, how is it having Jackson as a brother?" Stiles asks. "Just as horrible as you think it would be." Roy replies with a smirk.
You had a lot of fun meeting Jackson's 'friends'. But eventually you and Jackson were alone together in the kitchen. "So, are you and Roy together?" He asked out of nowhere. Your eyes widen. You liked Roy, you really liked Roy. At first you thought he might like you too, but he hadn't ever shown you anything more than friendship. You shook your head. "Uh, no..Why would you think that?"
He shrugs. "Well, you guys just seem really close, and he seems to get jealous.." You shake your head again. "We're just really close friends." You reply with a smile. "Oh, okay..Would you find it weird if I asked you to go on a date with me?" He asks with a smirk. You blush and smile. "No, I wouldn't find that weird at all." "Then, I'll see you tomorrow for a lunch date." He replies with a smirk before leaving the room.

You had told Felicity about Jackson asking you out, she was a little surprised and honestly a little disappointed but she knew it wasn't her place to say anything. You were already ready for your date, which was in a few minuets. You decided to meet Jackson at the restaurant"So, did you ever think that if you kiss Jackson it'll feel just like kissing Roy? Or if you and Jackson have-" "No Felicity, I hadn't thought about that, but thank you." You interrupt as you roll your eyes and laugh. "Woah." Roy says when he walks in and sees you all dressed up.
"Why're you so dressed up?" You chuckle. "Does there have to be a reason Harper?" "No, it's just the Y/N that I know is a proud supporter of a messy bun and sweatpants all day." He replies with a shrug. "Roy..I wanted to tell you something, Jackson asked me out.." "I wish I could've seen his reaction when you turned him down." He replies with a laugh.
You look down at the ground and bite your lip. "You..did turn him down, right?" You shake your head. "I said yes actually.." Roy's eyes widen and he breaths a laugh. "Oh, well good luck I guess. Who knows? Maybe if this works out you can move to Beacon Hills!" He snaps before storming off. You roll your eyes and sigh. You wanted to chase after Roy, but you didn't want to be late for your date.

You and Jackson had an amazing time at lunch, and afterwards he showed you around town some more, you guys had been hanging out for so long that it was almost dark outside. You guys were holding hands by the time you went back to Jackson's house.
"I had a lot of fun tonight." You say with an ear to ear smile. "Me too." He replies before crashing his lips into yours. He puts his hands on your waist and you cup his face. You eventually pulled away, but only because you were running out of air. You both smiled before you crashed your lips into his again. "Roy.." You whispered in between kisses. Jackson pulled away and moved his hands off of your waist.
"What'd you just call me?" He asked with a confused expression. You start to blush. "Um..I didn't call you anything, I didn't even say anything." You reply with an unconvincing tone. "You called me Roy." He replies. "Yes..I did. I'm sorry Jackson, I really am." He sighs and shakes his head. "I don't get it. You two obviously want each other, why don't you just tell each other? It's not that hard!" He exclaims.
"You make it sound easy.." You mumble. He rolls his eyes "That's because it is easy! You just have to be brave enough to do it." You smile. "Thanks Jackson." He shrugs. "No problem, and if you ever get bored of Roy, you know where to find me." He replies with a wink.

The next morning Jackson was washing his Porsche and Roy came outside. "So, how'd your date go yesterday?" He asks as he crosses his arms and clenches his jaw. Jackson rolled his eyes. "Don't worry about it." "I told you to stay away from her!" Roy exclaims. "Don't worry about it! She's not into me! She likes you okay?!" "What..?" Roy replies. "Just leave me alone and go talk to her please. Ugh." Jackson replies with an annoyed tone.
Roy smiles and walks back inside to find you packing your bags to go back to Starlight City. "Oh, hey I needed to talk to you about something." You say already starting to blush. He smirks. "I know." He replies before crashing his lips into yours. He has his hands on your back, and you cup his face before running your hands through his hair. "Hey gu- Woah!" Oliver says as him and Felicity walk into the room. You and Roy pull away from each other and look at them. Your faces start to turn bright red. "Finally!" Felicity exclaims. "It's time to go." Oliver says with a small chuckle. You grab Roy's hand as you guys walk out. "The real thing is so much better. " He smiles and kisses the top of your head.
Oliver starts putting everyone's luggage in the car. "Well, bye Jackson..this was..fun I guess?" Roy says with an awkward tone. "Yeah, feel free to..never ever come back." Jackson replies with a laugh. You and Roy laugh in response. "But if you do decide to come back, please call this time okay?" Roy nods. "I will, I promise."
You and Roy sit in the backseat of the car and you lay your head on his shoulder. "Still happy we took this trip?" He asks with a smile. "Very, very happy."
