Disclaimer: Arrow isn't mine. Just this fic.
We're going with a "you've got the wrong apartment" situation here.

For two guys that owned and operated a successful nightclub, they sure had a fair few parties at home. Felicity recants the thought however; Thea mentioned that it was someone's birthday this week, so the club does seem a little impersonal for a private party.

It might be Tommy's, Thea had skimped a little on any details other than the fact she was going and that she had invited Roy. A guy, from the Glades that she had met doing some volunteering. Felicity hadn't actually met him yet but Thea had introduced him to Oliver and Tommy and the party was going to be an introduction of sorts into Thea's life. Well at the very least they warned her about this one.

Felicity was contented with the heads up that Oliver gave her. He stopped her when they crossed paths in the lobby midweek; she stuttered out a thank you and was rewarded with a charming smile. It was early in the morning before work. Oliver was coming in. Felicity's mouth had a field day, along the lines of "You're getting in early… big night? I mean clearly if you're just walking in… the club must have run late. How do you not smell like alcohol all the time? Even though you smell really nice, I think I have that perfume." She really wished she'd stopped, actually she wishes she never started.

Thank the universe, it seemed like Oliver found her outburst funny and it was his laughter that stopped her. She knew her face was red but she thinks she succeeded in making them both feel embarrassed, when she looked up he had ducked his head a little. But he'd still grabbed her elbow when she had gone to make her escape; he was holding it the entire time he told her that he was going to have a party that coming Friday. He kept her in his grasp when he told her she'd be welcome to come.

She was ready for him this time though. Her own reaction to him the night they met surprised her. He had swept into her life on Thea's heels and sent her spinning. She can't deny what he did for her, with the dining chair, was incredibly thoughtful… but she barely knew this man. If she didn't have any previous experience with actual stalkers like that lacrosse player years ago, she would've easily branded him with the same title. Sure in the moment he seemed sweet but in hindsight she understood that his well-practiced charm was probably a result of countless night spent doing little else other than enjoying a privileged life and VIP treatment in bars and nightclubs. Plenty of chances to perfect his game.

She made up an excuse to bail; aside from the fact that social interactions were already incredibly awkward for her and that only seemed to escalate in Oliver's presence. Call her boring but it had been a ridiculously busy week of work. She'd been perfecting security software for the building's hardware when her manager complained to her about a headache and went home, loading her with his allocated complaints. Whatever. She'd have everything done by the end of the week, Walter was already keeping track of her progress, and it would only make her look more impressive. She stuttered out that she was on her way to work, that she was going to be late and so he let her go, his fingers slowly brushing off from her elbow.

Later that day, when Oliver himself was remembering their encounter he'd be surprised by his embarrassment. Usually he owns the walk of shame and considering his past they should probably rename it a strut. He'd also be a little surprised at the twinge he remembered feeling when she said no to his invitation; he'd brush it off as resulting effects of his late night.

She would have never made it to the party even if she had said yes; her eyes were dropping in the elevator on Friday morning. She called Barry instead knowing he was free that week, she did owe him a pizza for helping her unpack and she wasn't as angry anymore. Now that she no longer had to use a cereal bowl to eat the cheeseburgers she'd bring back from Big Belly Burger when she got lazy about cooking dinner after work, he was forgiven for his stupid prank. A night in with pizza, her friend and back to back episodes of Sherlock seemed like a great way to spend the night. Barry found it equally agreeable over the phone and she was able to face the day with a renewed vigour thinking about which of her wines would go better with which pizza.

Felicity had waited for Barry in the lobby, she had actually gone down to tell John she had a guest coming and that he should just let him up but instead she got caught up with chatting with Sara. By the time Barry had arrived holding the pizza, the party had already begun. Groups of well-dressed people, flounced by, making their way upstairs. Felicity and Barry had to fight their way into the elevator and then kind of stumbled out on to their floor, lacking the support of the elevator doors they were pressed up against. Some of the girls with the heels that were too high and the hemlines that were too short in the back of the elevator giggled.

"What's going on Lis?" Barry inquired pointing back at the elevator and obviously alluding to the music that had begun to play at an acceptable volume from upstairs.
"Oliver's having a party."
"Oliver? Like Oliver Queen, as in the name of Queen Consolidated business Oliver Queen? As in Queen like, Queen's Complex the building that we're standing in right now?" Barry follows her in and runs ahead of her turning to face her and walking backwards.
Felicity rolls her eyes. Barry almost hits her dining room archway.

Grabbing her friend's shoulders, she steers him toward the kitchen "Yes, that Oliver." When they're standing in her kitchen she stops walking, letting go of Barry and pointing towards the overhead cabinets over his shoulder. "The very same Oliver that helped me get my plates down." Felicity crosses her arms stubbornly, "cereal bowl for a week Barry!"

Barry smiles mischievously, "well you have them down now right?" When Felicity relaxes and nods, giving in, Barry laughs. "So where are they and your wine glasses so we can begin our night?"
"I'll get them, you go put the dvd in." She continues with a sharp look in his direction, "I don't want to find my sporks in the top cabinet tomorrow."
"But if you can't reach them, how will you find them?" Barry asks innocently as Felicity's face drops into a scowl. "Okay, okay…" and after a beat Barry continues, "But hey, you can always call Oliver to get them down for you." He quickly ducks out of the room laughing when a towel flies at his head.

Sherlock had just walked on to the empty plane, when Felicity heard someone pounding at her door. She could barely hear the faint yelling, considering the amount of music blasting from Oliver and Tommy's party. To contend with this Felicity had turned the volume way up two episodes ago. She wrapped herself in her comforter and put her glass down on the coffee table. Rounding it to specifically pass in front of Barry who had his legs outstretched on top of said coffee table bumping into his shins till he drew up his legs with a groan.

The person on the other side of the door is still slamming against it when she gets there. Looking through her peephole, she sees a younger man with a strong jaw, wearing a red hoodie over a collared shirt. Something about him seemed familiar, it all clicked in place though when Roy began to shout again, "THEA!... Please let me in!... I'm sorry I didn't show! I was nervous!... THEA!"

She could tell Barry noticed something was up, because he paused the episode and called out to her. She called back the she was okay, that it was nothing but she heard him get up and start towards her. Meanwhile Felicity got her phone out while she was opening the door, dialling Thea before she even saw Roy's face in the doorway.

Roy's "You're not Thea." Came the same time as Thea's "Hello?" in Felicity's ear did.
"Hey Thea, it's Felicity" the confusion washed off the kids face, replaced by embarrassment as quickly as the tips of his ears turned red.
Clearly these kids had a talent because, Roy said "You know Thea?" the same time as Thea yelled over the music "yeah! I know, caller ID! Whats up?"
"I think I have something of yours…" Felicity answers Thea as she drags Roy into her apartment.
Both chime in with a "What?"

Then Roy puts two and two together, "Is that Thea? Tell her I'm sorry!" He shouts trying to grab the phone, while Felicity paws him off. Barry meanwhile is just standing there looking at her looking torn between confusion and laughter. Big help he is.
Thea responds with shock, "Is that Roy?" then as if remembering her annoyance, she groans out an, "I'm coming." Just as she's hanging up, Felicity hears Thea call out, "No Oliver, I'm just going to go get him! I'll put him in a cab."

Felicity grabs the guys hood as he turns to walk back out into the hallway, slightly unsteady. "Where do you think you're going?"
Roy blinks, "to find Thea." Like its obvious. His breath though, smells faintly of alcohol.
No wonder he's confused, Felicity thinks as she spins him around, toward the couch instead, "just come sit, maybe have something to eat, Thea's coming here…"
"She's coming here?"
"Yes." Felicity nods slowly, snapping at Barry with her fingers and pointing to the few slices of pizza left and the water. Barry catches on quick and hands over food and water in a couple of seconds.

Roy holds the pizza up to his mouth, then with a weak smile and filled with mortification, "Waaiitt… this isn't Thea's apartment."
Felicity stands back and introduces herself "and this is my friend Barry" she points.
Roy's eyes widen showing some recognition "the cockroach hero" he laughs.
Felicity is content to giggle with him, "yes that's me." While Barry shoots her a look that says, he wants to hear that story later.

It takes about ten minutes till theres more knocking at Felicity's door. Which is honestly a ridiculous amount of time because Theas literally just coming from upstairs. Given the silence and the food and water, Roy's calmed a little. His head shoots up at the sound and he follows Felicity to the door like a lost puppy. Felicity looks back and he's planted his feet and braced himself, for his benefit she asks, "Ready?" She opens the door only after his stiff nod.

"Hey Felicity, how are you" Felicity supposes the questions is rhetorical, because Thea doesn't wait for an answer, "Where is he?"
Felicity steps aside to reveal a very sorry looking Roy.
"Hey Thea…"
"Don't hey me Roy Harper!" Thea punctuates her words with a poking finger in Roy's chest.
"Thea I'm sorry-"
"Sorry for what?" Her head tips sideways observing him, "standing me up? Not even giving me a heads up?"

Felicity goes to close the door, but a hand stops its swing, Oliver comes walking through her door once again. This time, he's in full over protective big brother mode. He spares her a quick nod and stands behind his sister with his arms crossed, glaring at Roy from above Thea's head.

Felicity quickly feels sorry for Roy. She tries to dissolve some of the tension, "Does anyone want anything to drink? Or maybe alcohol is not the best fuel in this situation… water? " she ends lamely. Barry looks at her and she can read the "Really?" all over his face. Oliver doesn't tear his eyes of the younger guy, Thea however looks around to her, "Sorry, could you maybe give us like 5 minutes Lis?" Again without waiting for her answer, Thea turns back to making Roy squirm.

Felicity just turns to Barry and grabs him by the arm dragging him toward the lounge. She wishes she could physically lower his raised eyebrows, they've been up near his hairline from the moment she called Thea and he's just going to give himself wrinkles. She can tell his head might explode from the questions so they sit around the corner and he unleashes in whispers.

"That's Thea and Oliver Queen." He squints at her, "Like billionaire Queens!"
"You have her phone number?
Why do you have her phone number?
How did you meet them?
When did you meet them?
You just let them in your house all the time, just casually?
Or do they just barge in like that often?
How long have you known them?
Why did that kid call you the cockroach saviour, or whatever, what's up with that?"

Knowing he'd want answers to all of his questions, she doesn't even ask which he wants answers to first. Instead she tells him all about how she met Thea, and in turn how Thea introduced her to her brother and her and Thea's casual coffee dates. Partly because he will not let it go and also to distract her friend from eavesdropping on the conversation in the hall, which is difficult because, well Thea is angry, and so she's yelling a fair bit.

By the time they've finished it seems like the group in her hall have finished too, the yelling had ceased a couple of minutes ago and the sounds of footsteps gradually get closer till Oliver rounds the corner with Thea and Roy in tow. Both siblings stop and look from Barry to Felicity, seemingly noticing his presence for the first time tonight.

Thea is the quickest, as usual, "sorry, are we interrupting?" Oliver cuts a look to his sister as if the idea is offensive. Till Felicity laughs and waves off Thea's question, she eyes Thea's hand in Roy's, "did you sort things out then?"
Thea nods, "Felicity, this is Roy, Roy is very sorry." she says, with an elbow to her boyfriend's ribs prompting him.
"Yeah. Sorry, wrong apartment," rubbing his neck with his free hand, "Thank you Felicity for calling Thea."

"It seems like I'm forever apologising to you for the men in my life," Thea jibes, looking pointedly at Oliver. She smiles sweetly, "Roy won't get the apartment number wrong again, even if I have to tattoo it onto his hand. But thanks for looking after him, Lis. We're going to head back to the party now; I still have introductions to make." Her pointed look is at Roy this time.

Though the young couple makes their way out, Oliver doesn't leave. Not before he rakes her eyes around the room stopping briefly on where Sherlock has been paused on her tv, to the pizza boxes and red wine on the coffee table and once again Barry sitting next to Felicity. "Are you still sure you didn't want to join us?"
"Yes Oliver, I'm sure." Felicity smiles softly at him, "and don't go too hard on Roy. The kid made a mistake."

With a curt nod, Oliver swiftly walked out. It wasn't until Felicity had heard the door close that she remembered so she raced after him, in hopes that she'd catch him before he got on to the elevator.
When she saw his retreating back, she called out to stop him.

"I forgot to say thank you, for the chair, I use it all the time now. It's my favourite one."
Oliver smiles, "It's your only one, and hence the reason I bought it for you in the first place. But you're welcome." He looked like he had something else to say, so Felicity drew the conversation out hoping that he'd say whatever he wanted to say. She asked about the weather and he looked confused. They'd been inside for the last 6 hours and she asked about the weather… so she quickly dropped the subject and tried an alternative, she got a response to this one at least.
"The party's great, I should really be getting back," and then Oliver's shoulders slightly hunched, "Your boyfriend would be missing you."
Ah… so that's it.

"Barry isn't my boyfriend," she replied quickly setting the record straight, "he's actually here on his girlfriend's request that I look after him. His girlfriend… Iris, she's a friend I met in central city." Felicity watched as the truth dawned in Oliver's eyes. "Any way I just wanted to say thank you and now… I have. I've got to get back to Barry before he breaks something. Not that he needs looking after, he isn't a child."
"See you later Felicity." He calls as she heads back to her apartment; she waves as she opens the door. Oliver's stopped when he hears a muffled sound of pain as Barry comes from behind the door, rubbing the side of his head and pouting.
Felicity frowns looking back toward Oliver, "maybe hold on the child part".

This fic is just getting bigger and bigger. I don't really mind, do you?
Also, if they see this, shout out to the few guest reviewers from the last chapter.
Cheers again for getting to the bottom.
