Felicity Smoak: the top Street racer and goddamn dancer!

Felicity POV

YAY! It's the weekend and I got a call from my friend Sean Asa and asked me to join in Nationals….oops! I'm not just the IT girl I'm more than Oliver thinks. I'm a National Champion Dancer and Street Racer, yep! I wasn't all nerdy in High School. Well I was but it was a cover, at night I will kick the shity glasses I never really need and pull me blue eyes contacts out and the blonde wig and let my green eyes and honey blonde hair with black and red and pink high lights free.

Anyway tonight I have a flight to Miami so tomorrow I can practice the moves and then at Tuesday go to New York for Street Race and then I go to support my twin in his Street fighting. Yeah I used to Street Fight but I stopped because my beautiful face was going to look awful if I continued not that I forgot what I learnt no I didn't. And whatever Dig taught me I already knew.

Well Oliver knows only half of myself not all and that's good because he is over protective, yeah he is hot and all I kinda have a little crush on him but I will let it pass as always.

Right now I was going to Oliver's house just to say that I'm going out of the town for the week and that I will need a week off the whole vigilante thing. Oh! A little detail for Thea, she knows my secret because she is also a Street Racer, she kicked my butt once.

She really good and I'm planning to take her with me she will loved to race again.

I rang the doorbell and just for my luck Sara opened the door, what that bitch is she doing here?

But behind her was Thea and I knew that meant that Oliver is home and I wouldn't talk to Thea freely.

Thea must thought the same thing because she grab my hand and we ran upstairs to her mum's study which is near Oliver's room.

Thea: I got a text from Sean Asa is it true? Yeah the know each other they met in a racer the MOB had come to support me and that's how they met.

Me: Yeah! Are you in? For the sake of all times! Come on! We need Queen back in the street and dance floor!

Thea: Okay you got me, let me pack and we leave in a few minutes, when is you flight?

Me: In one hour and it's not full so book a ticket and we are good.

Then I left and as I opened the door Oliver opened his and we smiled at each other.

Me: Oliver I have to go out of town for the week okay?

Oliver: What happen?

Me: Oh! Family meeting. I really don't know the subject.

Then Thea text and said she booked the flight and that she is packing and she will meet me in the airport so Oliver don't get suspicious. She is smart. Then I answer to her that she has to bring the bag with her hand gun and then my attention snapped back to Oliver when he gave me the answer I never ever expect to hear.

Oliver: I would love to meet your family so me and Dig are coming. When do you leave?

Me: Tomorrow. Smooth!

Oliver: Okay.

Then I gave him a forced smile and left. I went to pack and then took a shower. Then took a cab to the airport and waited for Thea suddenly I saw her coming out of the cab with her Street Racing indemnity on. She had red and pink highlights. And clothes so tight that you thought they were second skin and made out of leather.

She smiled and hug me, yeah I had my Street racing indemnity on too.

Thea: Ready for Miami girl?

Me: It that a question? Of Course!

Thea: You and Sean? What is up?

Me: Oh! No! He is with Emily, you know the other rich girl of the group.

Thea: Oh! My God! Emily?! Good she is hot. Come on we lose the flight and then we should play hide and seek with my brother and his best friend.

Me: How do you know that? I asked as we walked inside the airport.

Oliver POV

Okay that's weird! I was Googling Felicity's name when i saw a girl who is a Street Racer and Dancer and then she used to Street Fighting. She had went to jail 12 times for breaking in and then 2 times for driving while she was drank! Then I clicked the photos and I saw two girls, one with honey blonde and crazy highlight and green eyes and the other looked a lot like my sister. Then I called Dig to asked him if he knew anything and he told me that it was a Dancing competition on Sunday in Miami and A Street Racing Competition on Tuesday in New York, great!

I booked tickets for tomorrow and then I went outside to get some water and then head to the garage to fix my motorbike. But as I opened the door I heard a Felicity's voice saying:

Felicity: One hour and it's not full so book a ticket and we are good.

Where did Thea thinks she is going?

As I had opened the door Felicity opened my mum's study's door and we smiled at each other.

Felicity: Oliver I have to go out of town for the week okay? Seriously? Coincidence? I don't think so.

Me: What happen? I pretend to be clueless, I really care for her but as friend nothing more and if she has a dangerous past as I read then she needs protection.

Felicity: Oh! Family meeting. I really don't know the subject. Really? She is good at lying!

Then her phone rang and she smiled at the text then she answered then her attention was back to me. I wonder if it was her boyfriend or something? Is she even dating?

Me: I would love to meet your family so me and Dig are coming. When do you leave?

Felicity: Tomorrow. SCORE!

Me: Okay.

Then she gave me a forced smile and she left. Why she gave me a forced smile? Did I did something wrong?

And with that I lost my good mood and went to pack my stuff. Then and idea flashed in my head! She was lying! She had told Thea that if she booked a flight for tonight they will be okay! Where is she taking my sister?

I decided to spy on my sister because I'm her big brother and I have to know when my sister is making dangerous and stupid decisions!

I saw Thea living the house with a big suitcase and a hood over her head! She was wearing leather pants and unusually high boots! Something is not right! She got inside a cab and left. I ran to my car and start following the cab I saw that it stopped in front of the airport. Then a Thea got out of the cab with complete another look! She was wearing a red tank top and a lot of necklaces, she wore and black leather sleeveless jacket and the same leather jeans and boots. Her hair were with red and pink high lights and her eyes were black not green!

Then I notice she ran and hug another girl that looked like Felicity in more rock and punk style! She wore a black T-Shirt that had FUCK THE BULLIES logo and black skinny jeans and leather jacket and high angle boots. Her hair were honey blonde with black and pink and some red high lights and green eyes. Wait a minute! They look like the girls in the photo!

I have to follow them!

I called Dig and he changed our flight, thank God we had pack our stuff so I went home and grab them and then gave Dig a ride to the airport and then we were boarded to the plane and ready to go. Behind us were those, girls or should I saw Thea and Felicity, they were talking.

Felicity: Are you going to compete? Compete to what?

Thea: Well, I have five years to do that so yeah I think I will kick your ass on the road. Are you going to Street Fight against your brother?

What, she has a brother?

Felicity: Which one? "Which one"?

Thea: Not the hot one the other. Your twin! Twin?

Felicity: No, because I taught him how so he knows my moves, maybe I will kick some ass but I don't know with who. WAIT! You said that Nathan is hot? EWWW! Hahaha!

Thea: What? He is great in bed. Trust me! WHAT?! I looked at Dig which was sitting next to me and he was shocked as me but he nodded the way that let me know not to make a scene right now.

Felicity: WHAT?! EWW! When?

Thea: After Sean was arrested, you know the time you did that flash mob in Emily's dad's party?

Felicity: No way! Are you coming to the Nationals? Nationals in what?

Thea: Which ones? Street Racing, Street Fighting or Dancing?

Felicity: All of them. WHAT?!

Thea: Yes, Oh! do you got your guns? GUNS? Why they need guns? Do they know how to use them? Are they in trouble?

Felicity: Yes, do you?

Thea: Yes. Oh! Do you remember that time you won Rachel Black and he pointed a gun at you? And his men kidnapped Emily and me?

Felicity: Don't reminded me. Then CIA and FBI came in and we found out that Alex is a spy.

Thea: Or that after they big fight we had they asked us to join them? What did you say?

Felicity: That I will contact them but never did because then I moved to Starling City because Nathan went back to Military and my twin to Chicago. But I always think their offer; I mean imagine if we said yes, what would happen?

Thea: Well we would be assistants, ruthless and cold blooded murders. I'm happy I didn't said yes, come on! I was thirteen and I had a depressed mum and a brother being sea lost.

Felicity: Correct. Now sleep because we have to practice our butts off.

Thea: Yeah. Sweet Dreams Blondie.

Felicity: HEY! Speak for yourself Speedy! HEY!

After that they stopped talking, how I didn't see that coming!

Dig booked us two rooms in a Hotel of Ocean Drive and then we fall asleep.

Thea POV

Ah! Miami! Home of my really self, not the noise teenager but the kick ass racer and dancer and my best friend's hometown!

Me and Felicity were friends since she started working in my mum's company but before that I knew her really well from the racing, but we weren't close, but when she moved here we became best friends. When I was fourteen and her big brother was eighteen we were dating more like bed buddies but who cares, he wasn't dating anyone else so let's consider it dating, after three years we were officially a couple and we still are, now he is 23 and I'm 16 he is in Military I'm in school. We love each other so don't judge our age difference!

I guess if Oliver learn our secret lives and my love we would be so busted, I bet Felicity will lose her job and I would get kicked out but we already are milliners from the racing and street fighting so we don't have a problem if something like that happen. If that happens I moving to the house I bought in Miami last year and I and Felicity will be roommates!

Thinking of the life I might have with Felicity and Nathan put a huge grin in my face and I fell asleep.

I got awake by Felicity shaking me.

Felicity: Are you kidding me, I'm trying to awake you the past half hour!

Me: No, I'm not I was just tired so are we there yet?

Felicity: In one hour. I woke up because you had a phone call. She smirked I knew it was Nathan.

I took the phone and said: Hello? Is that the famous Nathan Smoak finally remembered his girlfriend?

Nathan: Sorry, babe I was in Iraq and you know.

Me: I know babe it was a joke. How are you holding up?

Nathan: I'm fighting, it's hard I saw some awful things and did.

Me: Oh! Baby don't beat yourself up, it's not your fault. You and Oliver had a lot in common you both beat yourselves up for things you were made to do. Whatever happened it's in the past. Take a deep breath and try to stay positive. We are here to help you. We all are so you are not alone.

Nathan: Thank you baby, you are my gold! I'll try. So how is my little sis?

Me: Crushing on my brother. I said and glance at Felicity and the stick my tone out to her reaction of sour face.

Nathan: Ah! Can I ask you something?

Me: Yes.

Nathan: Will you….accept me as your dance partner?

For a moment my heart flew out of my chest, was he going to ask the "Are you going to marry me" from the phone but thank God he asked me about the dance. Not that I don't want to marry him it's just he just came back from Iraq and I'm still in school. And that I'm in a plane and I can't kiss him after I say "Yes".

Me: Of course, babe. I miss you!

Nathan: I miss you so much you can't imagine what I've been through when I wasn't next you! WOW! Cliché much!

We laughed and then we said our goodbyes then Felicity and me just start teasing each other about our boys.

Oh! Yeah she used to date Paul Mark, more like it Pole Mark he was so cold that he gave me a froze bite every time I saw him.

Oliver POV

I woke up by the most awful dream ever! My sister calling someone "babe"!

Then I heard her conversation on the phone:

Thea: Hello? Is that the famous Nathan Smoak finally remembered his girlfriend? WHAT?

Thea: I know babe it was a joke. How are you holding up?

NOOOOOO! MY NIGHTMARE CAME TRUE! MY BABY SISTER IS DATING A GUY AND I DON'T KNOW THAT! Why he has to hold up? Is he ill? Is he going to die and leave my sis heartbroken?

Thea: Oh! Baby don't beat yourself up, it's not your fault. You and Oliver had a lot in common you both beat yourselves up for things you were made to do. Whatever happened it's in the past. Take a deep breath and try to stay positive. We are here to help you. We all are so you are not alone.

What does he know about me? What is his story?

Thea: Crushing on my brother. Is this Felicity's brother? Does Felicity has crush on me!?

Thea: Yes. Why is she so nervous?

For a moment I thought the world stopped, how long are they together? How old is he?

Thea: Of course, babe. I miss you!

WOW! My sister has a boyfriend?!

Now I totally I'm going to follow them around!

Time Skip: MOB's "lair" (Still Oliver's POV)

I follow them all the way where is that I guess is their first stop.

When Felicity and Thea stepped in a guy came out of the group that was dancing and said:

Guy: And this is our National Champions! I guess guys you remember Thea Queen known as Queen in Street Racing and Fighting and as Ms. T. in MOB and as the thirteen years old girl who kick one guy of Russian Mafia's Assistant's ass. And our very own Felicity Smoak is known as Miss Smoke in Street Racing and Fighting and as Felly in MOB.

Street Racing and fighting? Russia Mafia? What my sister is into?!

Thea: Well hello guys! Good to be back and thanks for the introduction and welcome speech, Sean.

Guy: Well I'm the leader. Suddenly a girl's voice echoed in the back of the room or call it whatever.

Girl: Co- leader babe! OMG! Felly! Ms. T.! She ran and hug them then a guy came and kiss my sister on both of her cheeks, weird, and then hug her again.

Suddenly my sister started doing some signs with her hands and I figured he has to be deaf. I didn't knew SLA?

Guy: Well we can put the song again so we can go to the Nationals?

Then a song start that I remember my sister being obsessed with a few months ago it was by Lizi Kay- Do You Like What You See.

In front of them was Felicity and she start dancing like she owned the dance floor!

Who is she? Is she the girl I love? Or someone who lied to me? Why my sister is lying to me?

So? What do you think? Should i continue it if yes what do you want to happen next? Review and tell me!
