Shoving the door open a gun armed in her hand, Catherine's face dropped as she moved around the corner and saw Sam was not chained up. Taking the safety cap off the gun she then looked around and smirked to herself. "You can't hide forever!" She shouted as she began to move around the crates to go and look for Sam. "Your mother in law might have given you a hand in getting free of those chains…but do you seriously think that you are going to get out of here alive?" She mused with a chuckle and a shake of her head.

Moving around the crates quickly and as quietly as she could as Catherine stormed in, Sam held onto the crowbar quickly, poking her head around the crates to see if she could spot Catherine. She could hear her walking. Ducking through some more crates she then looked up before she quietly began to climb someone of them. At least that would give her some leverage and see where Catherine was coming from.

"You know if it wasn't for your mother in law this would have planned out perfectly. You'd be gone…and they would have never have found your body so Steve would of thought that you had left him…I'd console the broken man, we'd end up getting back together and we would put you to the very back of our minds. He'd forget about you. Of course I'd have to get rid of that kid of yours…he'd be too much of a reminder… and kids aren't really my thing so he'd have to go."

Getting to a decent height, Sam then kept perfectly still as she saw the top of Catherine's head. Listening to her she couldn't help but roll her eyes. Was she actually serious? Steve would never go back to Catherine. Shaking her head she then glared down as she spoke about Alfie. Now she had crossed a line. Big time. Waiting for the perfect moment, Sam then pushed one of the crates down onto her. Now she was pissed.

Dodging the crate, Catherine then glared as she saw her and smirked before she pushed into the crates as hard as she could so she could try and knock Sam over. She wasn't going to let her get away. "You're fighting a losing battle here Sam…why don't you just let me end it quickly for you?" She mused up to her.

As Catherine pushed the grates, Sam quickly moved onto some other ones before she then jumped down, lifting her crowbar up she then waiting for the perfect opportunity before she struck Catherine's hand as hard as she could making her drop the gun before she pushed her hard back into the main room.

"You fucking bitch!" Cried Catherine as her arm was struck. Stumbling back as Sam pushed she fell onto her ass before glaring to her. "You're in for it now."

Throwing the crow bar away Sam looked to her. "No." She pointed to her. "You're in for it now." She snapped looking to her. "You know what you can do whatever you want to me. I don't care. But don't think so a second I am going to stand around and listen to you threaten my son." She moved closer to her. "You want to fight? Then lets fight. No weapons. We'll do this the old fashioned way."

Glaring to Sam, Catherine then got to her feet, holding her arm close to her she looked to her. "Fine. You want to do this the old fashioned way? Then brace yourself because I'm going to seriously kick your ass." She told her before she went in for a kick. She might have had only one arm but she was trained in hand to hand combat. She could improvise.

Dodging the kick Sam then swiftly and quickly threw a punch to Catherine's jaw before providing a hard kick to her chest, sending her flying. "You're the one who is going to get their ass kicked; you've seriously underestimated me Catherine. Now I'm going to enjoy teaching you a lesson on what happens when you threaten a woman and her family."

Ignoring the pain shooting through her arm, Catherine glared at her and moved her hands into fists. "Bring it fatty."

Sam scoffed as she looked to her. "Fatty? I'm pregnant you dumbass. Hardly fat." She shook her head before her eyes widened as Catherine practically jumped on her. As she fell to the floor she blocked the punches that Catherine threw at her, she got a few hits in but nothing major. Catching a punch as Catherine threw one at her, she used her free hand to punch her back before grabbing her by the shoulders and throwing her off her and jumping to her feet.

Wiping her bloody nose as Sam got a punch in, Catherine then glared at her as she kicked Sam as hard as she could in the chest before slamming her into the wall, pinning her to the wall by her throat. They were both covered in cuts and bruises. "What's a matter Sammy? Getting tired in your old age?"

Holding onto the hand that was around her throat, Sam then laughed and looked to her. "Old age? I'm not even thirty yet you fucking idiot."

Catherine glared at her, tightening her hand around Sam's throat. "You're the one who's the idiot. I'm going to enjoy killing you…then I'll enjoy winning back Steve…and getting rid of your kid…for good."

Those words. It sent something through her. Clenching her jaw tightly she then dug her nails into Catherine's hand as hard as she could before kneeing her in the groin. Grabbing hold of the chains she then jumped up as she then wrapped her legs around Catherine's neck and squeezed as hard as you could. She wasn't going to let her get away with this. Threatening her son? She was going to end her.
Hearing movement, Sam began to panic and squeezed Catherine even harder, panicking that it would be someone else helping Catherine to come and get her.

"Sam!" Came Steve's clear voice as he entered the room, bulletproof vest on and armed with his gun with the rest of Five-0 following behind him. Including his mother. He was reluctant to let her come but Doris knew where Sam was and all the exit and entrance points.

Despite hearing Steve's voice, Sam didn't flinch. Didn't look up. Didn't remove her legs from around Catherine's neck. Catherine was still struggling against her but she was powerless against Sam right now.

Walking in to the room more, Steve then sighed at the site he saw. Putting his gun away while the others kept themselves armed because of Catherine he slowly moved close to his wife and Catherine who was struggling less. "Sam…" He whispered as he looked to her. "Sam let her go…" He told her softly as he looked to her, moving to stand next to her as she clung onto the chains still mid-air. "It's over now…you're safe."

"I won't be safe until she is dead." Sam simply replied not taking her eyes off Catherine. "I don't give a crap what happens to me…but she threatened Alfie. Our son. I'm not letting her get away with it. He's a baby and she thinks it's acceptable to threaten to kill him."

"She'll pay…we'll make sure of that…but we'll do this the right way. You're not a murderer…" He sighed. "Sam look at me."

Reluctantly looking to him she sighed. Removing her legs from around Catherine's head she kicked her in the head one last time before jumping down. "I will kill you next time you even think about attempting to come near me or my family." She hissed at her.

As she was let go, Catherine coughed as she managed to get to her feet rubbing her neck as she looked back to Sam and glared to her, her neck red rare and bruises beginning to form. "Not if I kill you first." She rasped.

As Sam went for Catherine, Steve caught her in time before pushing Catherine towards the others. "Danny get her the hell out of here." He ordered before he then looked to his wife and sighed pulling her close to him. Cradling her close to him he kissed her head, keeping his arm tightly around her as he lent his head down onto hers. "I could kill you for not showing me that note." He told her with a sigh. "You should have told me what you were up too."

Danny grabbed Catherine by the arm and cuffed her before escorting her out along with Kono and Chin while Doris stayed behind and watched the couple.

Looking to her husband Sam sighed. "And what would have that achieved? You stressing out even more and growing even more facial hair and add to the nightmares you're already having?" She shook her head. "It's not fair to do that to you…I can look after myself Steve."

"She blew up a plane full of people thinking you were on it. You should have told me." He told her firmly before kissing her head once more before he sighed inspecting her cut face and busted lip.

Hiding her face in his vest she sighed to herself before wincing and moving her hand to her ribs.

Hearing her wince Steve looked to her and frowned. "What's wrong?"

"Think the bitch broke a rib when she kicked me…" Sam grumbled with a sigh.

Steve looked to her. "The baby?" He asked looking to her before looking down to her rounded stomach.

Sam looked to him and rubbed her bump a little. "Baby should be fine. I managed to dodge most of her hits."

"Maybe we should go and get it checked? Just to be on the safe side?"

Sam nodded and sighed. "Okay…but only after you've dealt with that bitch. I mean it Steve if she tries again I will kill her. I'm not having her threatening our son like that again."

Cupping her face he pressed his lips softly to hers before he pulled back and looked to her. "I will sort it I promise." He told her looking to her as he moved some hair out of her face. "Now Alfie is at Lou's. Kono will go and take you to go and collect him while we sort Catherine out."

Sam nodded to him before she then looked over to Doris and smiled a little to her. "Thank you for keeping your promise."

Doris looked to her and smiled giving a slight nod. "You're family. I wasn't going to let you down…I can see how much you mean to him." She smiled before she then looked to Steve. "I'm glad you are happy, Steve. Really I am. Your dad would be so proud of you."

Steve looked to her. "Well we will talk more when I finished dealing with Catherine." He told her as he kept his arm gently around Sam. Looking up as Kono came in he kissed Sam's head. "Go. I'll meet you back at the palace."

Sam nodded and gave her husband a kiss before she then headed over to Kono and left with her.

Steve watched her go before he then looked to his mother and sighed. "Are you going to stick around?" He asked looking to her.

Doris looked to him. "Yes…I don't want to leave Steve. I want to come home…I've missed so much in your life…and so much in the last two years. I don't want to miss anymore."

Steve looked to her before he then nodded a little as he then began to leave the warehouse, Doris following behind him. He didn't know whether to believe her or not but she would soon have to prove herself, especially if she wanted to be a part of Alfie's life. He wasn't having her coming in and out as she pleases like she had done in his life. He had to think what was best for his family. What was best for Alfie.
