Honolulu's Streets – 5:00 PM

"Stop! McGarrett! Stop, right now!"

Catherine was running after him for about ten minutes and the guy didn't slow down not even for a bit. Only runs faster trying to catch a suspect. She isn't a big fan of working with an ex-seal. But she had to follow orders. Her boss have a connection with this guy, now working as security adviser. What really gets on Catherine nerves is his attitude... To Steve doesn't exist anyone in the investigations besides him and his ninja skills. Later, her boss, Chin Ho Kelly, will hear her complaints. When Catherine gets near them, McGarrett is already handcuffing the guy.

Catherine does not know what irritates her more: his attitude or the fact that he really manages to catch any guy.

"So, Rollins... It took you some time till you get here. Stopped to get a coffee?"

And there it is... His smug attitude that really annoys her. He is smirking and she is trying really hard to not kick his butt. She glares at him.

"You should've waited for me"

"Maybe one day, in a different situation"

He has the courage to give her a wink. Catherine doesn't say another word. They are in front of a suspect, so she doesn't want to argue with him right there.

Steve seems to get her message. He doesn't say nothing more to her while they put the suspect in the car. They are heading to HPD with him driving, as always, and Steve is on the phone with everyone talking about this case to wrap this up.

She had worked with him a few times and he has always the same behavior. Why such a beautiful man would be so smug? Yeah... She thought that he is beautiful, so what? It doesn't change his character... Or at least the character that he shows to everyone. She has a hard time to understand how he could have great people as friends like Chin and Danny... She is a woman and she can't hide the fact that he is beautiful. With those blue eyes and rock body always wearing a casual suit. In another situation, and if he had another temper... God... She would die to be in his arms.

For a second he catches her looking at him.

"Want to say something, Rollins?"

She blushes slightly. Damn.

"No. Right now I won't say anything"

HPD – 6:00 PM

They enter in HPD with the suspect and go put him in jail. After that, Catherine heads to her boss's office when someone catches her arm, making her stop.

And of course.

It's him.

"Look, I'm sorry about getting the guy alone, but we managed to get him"

"No. You got him! I'm tired of being in the back of every investigation that we work together. This is unbearable"

"C'mon, Catherine. You helped with other things..."

"What? I'm a field agent. Sorry. So I must to be on the field. You just don't get it!"

She looks at him and he lets her go.

When she is getting near to Chin's office he is just coming out.

"Rollins! Great job! You and McGarrett do a great team!"

"Yeah, sir... About that, we need to talk"

Seeing the seriousness in her eyes, he steps back and opens his office's door.

"C'mon in... Don't tell me you're going to talk again about him..."

Closing the door behind them, she says.

"Yes, I will! Chin, I'm tired of him and his attitude. Again, he run off chasing people without telling one thing to me. I don't even know what he thinks. He doesn't say anything and keeps acting on his own. I'm tired of this shit! Put him with another person!"

"Catherine, calm down. He did the job, didn't he?"

"I can't believe you just said that"

She is pacing in the room.

"Yes, I did. Look he is a great help and I won't deny it. Believe it or not you two work well together"

"Chin, I don't care! I can't work like this. If you keep accepting his help it's ok. I get it. He is your friend and has many contacts. That's with you. I don't give a shit about that. But, next time, put him with another one. I'm serious here. I'm done."

She is angry and tired of it and leaves Chin's office. She looks forward and Steve is leaning against the wall watching her with a calm expression. And that really annoys her too.

She goes to her table, puts some things on her bag. Chin calls McGarrett to the office. She watches Steve going there, but she is done with this and only wants to rest. She grabs her things and heads to the door when she hears someone calling her name.

"Catherine! Don't go! I need you in my office again!"

Chin.

She sighs and turns to his office.

Entering she sees her boss and McGarrett looking at her.

She close the door. This can turn nasty.

"What?"

"Catherine, I've talked with McGarrett and you two have to work things out."

"Again? We've worked more than 6 cases together and it's always the same thing. I've already told you, Chin. I don't care. I won't work like that anymore"

Steve doesn't say anything, just stares at her and then to Chin while he speaks.

"Apparently, he will only working with us again, if he it is with you."

Catherine is stunned. She couldn't expected this.

"What the hell, McGarrett? Are you... what... a five years old boy who is making a scene because he wants an ice cream, or what?"

For the first time he speaks.

"Maybe... But I just want to prove you that we can work together. Despite my reckless attitude, you know we can work together... So, do you accept this challenge?"

"See? It's because of this kind of speech that I am tired of dealing with you"

"I know, Rollins... But I also know that you can't say no to a challenge. So, here it goes: I'll prove to you we can work together. If that doesn't happen, the next time, I will work with another officer. So, what do you say?"

Chin scratches the back of his head.

"I don't know if this will be a good idea..."

Catherine just looks at Steve. Now, he is really being surprising. How does he know that she likes challenges? Now she doesn't know what to do, but deep inside she knows she can't back down. For some reason, he has that effect on her. She looks straight at him.

"I'm in. When is the next case, boss?"

"I don't know. For now we don't need him... But the way things have been on the island, I know that we will need him soon"

Steve is smirking with her answer and Catherine looks at Chin.

"Can I go, now?"

"Yeah... Of course."

"Good night"

She left the office. She can't help but think in what just happened.

Chin's office

"What the hell was that, Steve? She was really pissed... I can put you to work with any person on this department"

Steve can't wipe the smirk from his face.

"Sorry, man... That just came out. C'mon everyone likes challenges..."

"This is going to be interesting..."

"Let's see... I couldn't let her get away..."

"Excuse me, Steve? What are you saying?"

"Maybe exactly what you're thinking"

Chin can't help but laugh.

"You're playing with the fire, McGarrett…"

Steve doesn't say anything, but he can't wipe that smile from his face and he doesn't even know why.

"Well, buddy... I hope you know what you're doing. I don't want to lose her. She is a great officer, and you know that this kind of things can be messed up, man."

"Trust me Chin... I'm just kidding. She hates me right now, nothing will going to happen"

"Hey, I know you. So, I'm just saying: don't screw this up"

Steve doesn't have any clue what could happen between them. But somehow he just wants to be near her. And that feeling is strange for him. And scary. Very scary. And Steve McGarrett not get scared. He needs to find out what is what he feels when he is with her.

Local Bar – 10:00 PM

After everything, Catherine had decided to get out of her house and have a drink on a bar nearby. She is sitting on a bench with a beer in her hand. She couldn't stop thinking about what had happened on that office. How could he challenge her like that? And why she didn't said no? Because of her competitive side… Perhaps she had shown that side of her personality too easier to him. Damn him! Damn Steve McGarrett… Steve… He was a strong man and she couldn't hide that she feels something. Of course she didn't like work with him. But when she saw him running after a criminal, again, alone, she didn't only felt her work disrespected. She also felt some worry. Worry? Wait. No. That is impossible. How could she be worried about him?

Catherine decides to drink a little bit more to stop thinking. This is the best thing to do right now.

Steve feels the need to let go off some steam. This last case was hard and everything was too much intense for him. Finally they were able to finish the case, but, though he did not admit to her, Catherine was right. He was doing everything alone. He can't find any excuse for being like this. He is used to work on a team, he was a Seal for God's sake...

He gets to a bar in the city center. And it doesn't even take one second to realize that she is there. He smiles and can't help himself. It is like he had lost the ability to control his steps... Slowly he goes towards her. Her long black hair cascading over her shoulders. When he leans on to her, he feels her perfume that, strangely and unexpectedly, makes chills run up his spine.

"Didn't know you used to come here"

She looks at him surprised. What was he doing here?! She lost her words, taking in the sight of him. For the first time he is not in a suit, but in a pair of jeans and a blue shirt.

He motions to the vacated bench beside her.

"Can I?"

She regains her composure.

"Commander McGarrett asking for permission? That's new"

He smiles at her sarcasm and sits beside her.

"Longboard, hum? I'll have one"

"Yeah? Make it two"

He laughs and makes an order to the bartender.

She doesn't know what she is doing but she keeps talking.

"I come here often… And you? I never saw you here… Looking for some distraction for tonight?"

He grabs his bottle and looks directly at her.

"Maybe…"

"Hum… Or do you came here to make me another challenge?"

Her tone is not accusatory, but somehow he feels the need to say something about that.

"Yeah… About that… Uh... Maybe that wasn't the right way to make my point, but…"

"Which point, McGarrett?"

He smirks at her.

"You know what my point is... Look, I only wanted to have another opportunity to show you that we can work, properly, together"

She just looks at him. There's something about this man that fascinates her. She knows this from the beginning, but always tried to avoid that feeling.

"To have another opportunity… You are always like that when you ask for another chance?"

He drinks his bottle really quickly and asks for another. She is also a challenge.

"Wow… Thirsty? Or am I making you nervous?"

Now he laughs.

"Making me nervous? C'mon, Rollins. You can't keep up?" He asks trying to distract himself from the nerves, because she is right. He is nervous.

She raised an eyebrow.

"Really? So, you really came here to make me another challenge... But you know me. I can't say no to a challenge. Bring it!"

Well, maybe this could be interesting, thought Steve. He nods and asks another round.

After two hours of drinking, Steve and Catherine were laughing out loud, telling stories about them. Mostly about Catherine's time in the Police Academy and Steve's in the SEALs.

He feels that she is easy to talk with. Catherine thinks that he is not an arrogant man after all. Or maybe is the alcohol talking… For both of them.

"I loved that the guy ran off of you when he saw you!"

They laugh again.

"Yeah... I don't know why people keep doing that!"

It's been some time since Steve is so relaxed. And Catherine makes everything so easier.

"So, you passed half of your life in a boat, uh?"

"Hey, it's not like a regular boat, alright?"

"You are telling me that you don't know how to sail?"

"Of course, I know how to sail! But, the Navy…"

Smiling, Cath interrupts him.

"Yeah, Yeah… So if you learnt how to sail there, you were in a boat… Wait, If you've been on a boat and know how to sail, you are… A sailor!"

They can't stop laughing and drink what's left of their beers and at the same time, they put the bottles on the counter.

"Yeah, I'm a sailor!"

They laugh again when a clock on the wall catches Catherine's attention.

"Oh... It's late. I have work tomorrow... Sorry McGarrett, but some of us have a real job to do, so I got to go"

"What? Do you think I don't have a real job?"

"No, I don't think so" She laughs. "C'mon, I'll pay and I'll go…"

She is reaching for her purse when she feels his hand over hers. And it is warm and delicate. She looks at him and he is staring at her. He doesn't know what made him put his hand on hers but it feels so good. He is the first one to talk.

"It's ok. You'll buy for the next time"

"No. I'll pay my share, then"

She doesn't move from his touch and they are staring at each other. None of them backing down. Suddenly he breaks a smile.

"Alright then. I'm not making another challenge with you"

None of them wants to break that little physical contact. But Catherine is the first one to pick up for some money paying the bill.

"I'll go too", he whispers.

Definitely he doesn't know what he is doing.

Catherine manages to stand up alone, but the alcohol is affecting her balance. She doesn't want to show it to him, though. She is a woman who can handle the things by herself.

They come to the door and he leaves it open for her to pass first, being a gentleman. And, God... She looks amazing, wearing simple jeans and a black tank top. Her perfume is again on his nose and it's intoxicating.

She knows he is staring at her and, what the hell, she has nothing to lose.

"So, you'll be there all night?"

Again, his body is acting as if Steve had no control over it. He goes straight to her, grabs the back of her head and kisses her. He kisses her hungrily. Catherine is taken by surprise but goes with him. This was too good to stop and she grabs his hair. Feeling her need he leads her to the street, leaning her against a building, putting his hand against the wall, to not hurt her head. They stop kissing, trying to catch some breath. He looks at her, licking his lips. He just wants to feel those lips again. She is grabbing his hair, trying to gain some support and this time she is the one who takes the initiative. And the hunger and the lust are the same from the previous kiss. All her tension towards him was in that gesture and she takes her time feeling every part of his mouth against her.

They separate again, breathing hard. They both lick their sore lips. Steve is the first one to talk.

"This is… Another kind of challenge, I think…"

And he smiles. That cocky smile which usually annoyed her. But now she only thinks that it suits him.

"Maybe a challenge that we shouldn't take…"

They are looking deeply into each other's eyes.

"Maybe", he says.

But their actions don't agree with their words. And both of them have the same instinct. They lose themselves in another kiss.

Nothing can stop their emotions.

They pull apart and Catherine grabs his hand. Without a word he follows her. It was like he was in another life, with no burdens, with no regrets, with no fears, just here. Just him and Catherine.
