(continuation from the previous chapter)

And Steve remembers It's ok, John, she had said. John... John was the name of his grandfather. The father of his mother. He always told Catherine that he loved his grandfather John. Just because he was a guy with principles, he had never wished for his daughter to marry with a guy like Jack McGarrett.

Grandpa John never came to his house, Steve always went there on vacations. He had always refused to be on a McGarrett's house. Just because of that, Steve always thought that he was the best guy ever…

Shit. That kid can be his son. That would explain a lot.

Bookstore

Catherine keeps looking in the shelves without any focus on that. She could only remember Steve.

"Hey, maybe this one is good" John shows to his mother a book and that makes her to wake up for the reality.

"Do you want to have it? As she is speaking, she notices Steve leaving the bookstore. She breathes hard. God. She is not feeling well but she has to be strong. She looks at her son.

"Mom?"

"Sorry, John. I'm a little distracted today" She smiles at him "Let me see if this is a good one..."

She grabs the book from his son's hands, trying to focus her attention in another thing besides Steve.

McGarrett's Home

Steve gets home and heads straight to the office where he knows he will find Danny.

"Danny, I need to talk with you"

Danny looks up at him and sees his serious face.

"Good, I was going to the warehouse, maybe we could go together"

Steve nods and they get out from the house.

Danny's car

"What happened Steve? You were caught or something?"

"No. Look, this morning I managed to talk to Chin. He received the first documents about the offshore accounts."

"Good. That's good. But what's the matter?"

"Danny, how old is Catherine's son?"

"I don't know exactly... But I think he's around sixteen... In fact, I heard something about he had turned sixteen years old a month or so ago"

Steve starts to count. He is sure Catherine hadn't cheat on him, back then. She didn't even know Billy, when they were together.

"Shit" He mutters.

"What's going on, man?" Danny asks with a worried tone.

"I think... I think he is my son" Steve quietly says.

"What?!" Danny almost jumps on the seat. "What the hell are you saying?"

"Look, doing the math, he was conceived before I went to Hawaii"

"What? No... I think he has born with 8 months, I think... But what caused all of this?"

"I spoke to her this morning"

"You spoke with Catherine? Today?"

"We've talked about... well we sort of talked about things"

"Sort of?"

Steve looks at Danny.

"Look, something is not right. About her, fifteen years ago, but, mostly, about the kid. If he is my son than that's an explanation for her run off and married Billy. I was gone!"

Danny doesn't take the look from the road.

"She could've lied, and the baby was born with nine months... You have to know this, Steve. If he is your son you have to know, man! They are on the mouth of the wolf"

Steve shuts his eyes.

"I know, man! But I wasn't able to make any more questions this morning... I have to talk with her. Only Catherine can tell the truth"

"We'll think about a way to do this"

"I met him... I met her son... And I don't know why, but it was like I knew him, you know? I don't know, man... If he is my son, I don't know if I could forgive her"

"Steve, if he is your son, you have to take him out of this mess"

Steve looks at Danny.

"I know"

Rollins's House - Catherine's Bedroom

God, she thought. She almost had told him the truth. What the hell is wrong with her? If John didn't come up, she would tell him everything. But who can blame her. Those kisses made her forget everything else around her. She breathes hard and tries to calm herself, pacing the room. Steve knows that she didn't love Billy and she has a little hope that he will hate her a little less. She was incapable of lying to him again. Especially, on that situation… And she doesn't know what she will do or how she will react if she sees him again.

McGarrett's House – 09:00 PM

After some meetings, Steve was able to, finally, get home. He just need a little more time to get all the evidences he needs to burn down the business. The problem is the moles on Police Department. But he has the best agents he had ever met and he has to believe in that. Danny has been the best, but something is missing and he needs some other help. He had just sat on the couch when Lynn interrupts his thoughts.

"Hey, honey. I thought I wouldn't see you today" She kisses him.

"And why is that?"

"I'm going to my parent's house... Daddy's birthday is coming, and we need to get everything ready on time."

That new information could be good for him. He could get some more info from Andrew's house too. Sorry, Lynn, but your family will going down too. He is not really sorry for that, after all, his marriage was part of the big plan since the beginning. He needs to talk with Chin and Kono.

"… Rollins family"

The mention of that name made him stop thinking and actually hearing what his wife is saying.

"What about Rollins?"

"Steve, do you ever listen when I'm talking to you?"

He tries very hard to not roll his eyes at her.

"I'm saying, that Rollins will be there too"

Steve's eyes widened.

"Steve, don't be mad at me. You know my father always had connections with them"

"I can't believe it..."

"Look, Don't make a scene. This is the first time you'll be there, so calm down. Maybe Harrington's wife is going this time"

The mention of Catherine made him clenching his jaw.

"What do you want to say with that?"

"Well, you know... She never goes to this kind of reunions... What is fun is that she doesn't even care if her husband goes with one of his mistress"

"And how do you know all of that?"

She laughs.

"C'mon, Steve. Everybody knows that. Everyone thinks she is kind of crazy, you know? When her dad died everything was even worse. She stopped caring. At least they have a son…"

If he is Billy's son, he thought. He can't imagine Catherine being like this... Like she had given up.

"When is this party?"

"Tomorrow"

Despite being a danger situation, it could be an opportunity to talk to Catherine.

"Alright. I'll be there"

Steve stands up from the couch and leaves a kiss on Lynn's face.

Next Day

Lynn's Father House – 08:00 PM

Steve has been there one or two times. Visits those were important for him to know the space. He has two important missions that night. At least he could count on Danny's help. Steve is on the living room, with Lynn by his side, talking to his father-in-law. He takes a sip from his red wine and pretends to be the human that is more interested in their talk. Occasionally, he is glancing to the door, hoping to see her. Steve is a man that doesn't do anything without having a plan.

And, finally, here she is. She is behind Billy, smiling to the one who opened the door for them. And he takes a second to watch her. The black dress she is wearing accentuates her curves and he can't deny it. She is beautiful. Steve shifts his weight under toes watching the way Billy is grabbing her waist. Something is not right. He knows that she doesn't love her husband but the way he is putting his hands on her shows a little of brutality.

"… what do you think, Steve?"

Steve turns his gaze to his father in law.

"I think you should, sir. It could be a good arrangement"

He doesn't know how but he managed to hear about the deal they were talking about.

"Good night, gentlemen"

Her husband is right before him. He can't help but feel a little jealous about Billy, though he has to remain strong. His father in law hugs Billy.

"Billy, meet my son-in-law"

Steve makes the first move and extends his hand. Billy accepts it, reluctantly.

"And who is the lady?" Lynn's father asks. Steve can see the surprise in Catherine's eyes.

"Oh, right. This is my wife, Catherine Rollins"

Steve takes her hand and leaves there a kiss.

"Pleasure to finally meet you…"

Catherine looks into his eyes, for a moment and says.

"The pleasure is mine" she says quietly.

"I'm Steve's wife" Lynn chimes in. Steve let go off Catherine's hand and straights himself up.

Catherine feels like that someone is slapping her face. Again. Steve's wife is beautiful, that's for sure. Catherine stands there for a while, since Billy is talking about some things with Andrew. And she can't help but notice the way Steve and Lynn interact with each other… They seem to be very affectionate with one another and she doesn't understand what that meeting on that bookstore was about. Steve kisses Lynn and it seems so real…

She is totally confused and the sadness is all over her face. Was Steve playing with her? God, what she got herself into? Letting Steve know that she doesn't love Billy, just to see him smiling with another woman on his arms…

After dinner, Billy wants to dance with her. And she complies. At this point, she has nothing to lose and she has to play her part on this scene. So she accepts Billy's hand and they head to the center of the room where some couples are dancing. It is a slow music and she just goes with him. She closes her eyes and leans her head on her husband's shoulder. Its better this way, at least she doesn't have to look at Billy. And she imagines that she has seventeen years old again, holding Steve's hand, feeling his skin against her. She smiles and enjoys her imagination which brings some tears to her eyes. How she'd been happy in his arms…

The song ends and Billy says.

"Let's go. I need to talk to Andrew"

Catherine opens her eyes and tries to pull away her tears while Billy goes to another room. Catherine takes that chance to go to the bathroom, at least to brush up her makeup. She asks where it is the bathroom and she goes to a small corridor. Fortunately she doesn't have to wait, the door is open so it is available.

Steve knows where she is. And it is the right time to talk to her. He goes to the same small corridor and knows that the balcony that is next is empty, because Danny had told him seconds ago. Steve excuses himself and goes there, with Danny having his back.

Catherine is leaving the bathroom when she feels a hand on her arm.

"Come with me"

She wants to protest, but his grip is strong and she can't make too much noise. That will put them in danger. Steve doesn't say a word while he leads her to an old room that has a small balcony. They enter and Steve shuts the door.

Catherine steps away from him. After what she saw, she wants distance.

"What the hell do you want, Steve?"

"I need to talk to you"

"Alright, talk. Fast. We can't be here!"

"Don't freak out. Someone is having our backs"

"Don't freak out... You have some nerve..."

"Look, I don't want to fight"

"So what the hell do you want?"

"I need to know something"

Catherine's heart is racing. She is almost certain what he will ask her and she doesn't know what to. So she does the only thing she could think of: she tries to avoid it.

"Really, I need to know something too... Since when you've become a heartless son of a bitch, Steve?"

Her voice rose slightly. He is taken aback. Why is she so mad at him?

"What are you talking about?"

And now she is not afraid anymore. She feels anger. She feels anger at him and his attitude.

"Oh, don't you know?" And she takes a step further in his direction. "Why the hell you brought me into that bookstore bathroom and asked all of that questions just so I learned right now how you have been happy?! Are you fucking kidding with me?!"

Steve's eyes widened. She is jealous. He can't lie. He wants to smile with amusement, grabbing her and show her how much he loves her, how much he craves her. But he can't. He has to ask an important question.

"We can talk about that another day. Not now."

"What? You wanted to know if I loved you and I open my heart to you, and what? You rub in my face how happy you are with your family?"

"Catherine..."

"What? You wanted revenge, isn't it?!"

"Cath..."

"Don't call me that, stop with the bull-"

Steve grabs her arms and interrupts her ranting.

"Is he my son?"

His tone is firm. All the seriousness in that question made her stop. Despite the anger she felt, she realizes that the question just came out from his mouth.

"Is John my son?"

Catherine can't say anything and the silence fills the room, but Steve breaks it.

"Tell me, Catherine. Is he my son? I need to know that now!"

Now the fear is back. She is terrified of what he could do to her.

"I did the math, Catherine"

"Everyone knows that John has born with eight months" it's the only thing she can say right now.

"People lie, Catherine... You could've lied. Like I said, I did the math, and you said I'm so sorry for lying, in that bathroom. His name is John, for God's sake!"

Catherine swallows hard and just looks at him. Why she can't lie to him? She shuts his eyes while he asks again.

"Tell me! He is my son, or what? You have no idea what's going on. If he is my son I need to protect him. TELL ME!"

Steve looks deeply into her eyes, grabs with more urge her arms and almost slams her to the door. He doesn't want to be an animal. But he needs to know the truth.

"Protect him from what?" She whispers while opens her eyes. They are in danger?

Now, Steve knows. By the way she is answering to him, he knows: he has a son.

"I can't believe it. How could you? I'm the heartless one?!"

He is a wise guy. Always was. She didn't have to say yes. Just by her reaction he knew he was right. The grip on her arms isn't hurting her... at least not much as his words. She is sure: he will despise her.

"How could you hide him from me? And give him a father? A criminal? What the fuck were you thinking?!"

"Steve..." She quietly says.

His grip is stronger and the tears start to run down Catherine's cheeks.

"We could have done things differently... If I knew I have a kid…" his mind starts racing. If he had knew that, he'd never ever joined the mission, because John will be the first one to suffer the consequences of this war.

Catherine doesn't move from her place, but she needs to know what is happening.

"What? What could've been different?" She asks and manages to look at his eyes. They are burning with rage. He is furious.

"I don't know where we could be now, you made that choice for me!"

He is almost yelling at her and finally let her go. She almost stumbles to the floor, but manages to lean on the door, breathing harder. ""I didn't know what to do. You left, Steve. You left, and I knew that my father would've killed me… He would've killed me and my son. And you… I couldn't… I. I was weak, yeah. I'd only found out about the baby two weeks after you left. I was lost and my father had already presented me to Billy. One thing lead to another. I just wanted to protect you, protect your son"

"No. You wanted protected yourself."

That hurts. Only her knows how she had suffer in that life. He is hurt, but she can't accept his words.

"You have no idea what you're talking about"

He turns to her and she can swear that she see some tears there. Steve feels betrayed by her, but, more than that, he is worried about what will happen. Maybe he has to tell her the truth to her put John away from here.

"Oh, yeah? I don't? So tell me, what I should know to not look at you like a selfish bitch!"

Catherine is taken aback by his hard words. He grabs her arms again.

"TELL ME! Because, you have no idea of what you've done!"

"Let me go, Steve"

"Are you going to tell me that you suffered? You hide my child from me! You let someone else took my PLACE"

"Steve, stop!"

Steve seems to wake up from a nightmare with her scream. He let go off of her and goes near the window.

"You don't understand what will happen… This is so messed up"

She can say that something more is bothering him besides the truth about John and his heart is clenching.

"What is happening, Steve? Talk to me. John is in some kind of danger?"

"Billy knows that he is not his son?"

"No"

He breathes hard.

"You lied well…" He is burying another knife in her heart, but she doesn't care. She wants to know what's going on.

"Steve, what is happening? You can hate me, but if my son is in danger you have to tell me!"

Steve looks at her and he is not certain about what he is going to do. But he needs to protect John and the only way to do it is talking with her. he knows that Catherine and Billy doesn't have a life together. They don't are a couple, that's for sure, at least with all the evidence he has.

"I'm a cop"

"What?!" This is too much. Steve is about to speak, when his phone starts to ring. He grabs it and it's Danny.

"Yeah?"
