"Hey Sam, what you doing here?" Asked Kono with a smile as Sam walked into HQ.

Glancing around slightly she then looked to Kono and Chin at the table top. "Are Steve and Danny around?" She asked as she looked to the two of them.

"No they're following up on a lead for this case we're on…" Chin told her before he frowned a little. "Everything okay? You seem a bit distracted."

"Good." She mumbled before she dug through her bag and grabbed the note she had received and passed it to them. "You could say I'm a little bit distracted."

Kono frowned a little. Sam looked too distracted for her liking. Taking the note she opened it, her mouth dropping slightly as she looked to her friend. "Please tell me you have shown Steve this."

"No I haven't and I intend to keep it that way." She told them both looking to them. "Steve is still struggling. He's having nightmares about everything that's happened. If I show him this he's going to completely freak out…same with Danny. I don't want either of them knowing until I get to the bottom of it."

"When did you receive this?" Chin asked looking to the note before he then looked to Sam once more.

Sam sighed as she ran her fingers through her hair a little. "Three days ago."

Kono looked to her and shook her head. "Sam you are a walking target, you have to tell Steve…who even sent this?"

Sam rolled her eyes. "I'll give you three guesses." She grumbled before giving a slight shrug as she looked to them. "I can only think of one person who wants me out of the way that much. "

Chin raised an eyebrow and looked to her. "You think Catherine is behind this? I thought that she had given up on trying to win Steve back." Chin sighed. "Sam you need to tell Steve."

"No I don't." She told him firmly. "If she wants to play games then she can bring it cause it's her who is going to lose."

"Sam if it was Catherine then she blew up a plane…" Sighed Kono as she looked to her. "She killed hundreds of people thinking you were on that plane…she's clearly not going to stop until you are out of the way. You're in real danger. Catherine was in the navy…she's not stupid."

Sam looked to her. "She is stupid. Because she's seriously underestimated me." She looked to them. "I'm serious when I say I do not want Steve or Danny knowing."

"So what do you plan on doing Sam?" Chin asked looking to her. "You're nearly five months pregnant…it's not just you that you have to think about not to mention you have Steve and Alfie to think about as well."

"Yeah well I'm fed up of her thinking she can come and stick her nose in and try and control everything. Steve is my husband not hers. She has no right being here anymore not to mention she's pretty much a terrorist now! She blew up a plane. She's a murderer. She won't be getting off lightly."

"You're going to need proof it's even her in the first place." Chin told her.

"I'll get my proof don't worry about that."

"So if you don't want us to tell Steve and Danny what do you want us to do exactly?" Kono asked looking to her.

"I need someone to keep a track of her. See where she is at all times while I do my digging."

"Sam you are playing with fire." Kono warned looking to her.

"Look…I know you don't like it but I've got to do this. Please. Just help me." Looking to her watch she then looked to them. "Look I have to go pick Alfie up from day care…i'll come back after I've picked him up…"

"And what if Steve and Danny are here? What are you going to tell them?"

"I'll think of something." She told them before she backed away heading down the corridor. "I have to go. Please guys…" She looked to them before she then headed out of the palace and down to her car.

"I'm not happy about this." Chin told Kono as he looked to her.

"Neither am I…" She sighed as she put the note in her pocket before she looked to him. "If we track Catherine's phone then we need to trace Sam's too. Just to be on the safe side."

"She has no proof that it's Catherine after her…technically that note could have come from anyone."

"Do you know anyone else who hates her?"

"She owns a law firm Kono…she might have made it the most respected one of Hawaii but that's not going to do her any favours with people who like to get on the wrong side of the law. I think we should tell Steve."

"But you heard what she said…Steve's having nightmares still. We both know he's still struggling. The guys forgotten how to shave lately…let's just give her a few days…we'll keep an eye on her. Only worry Steve if we really have too."

"Okay fine but the moment she's in danger I'm telling Steve."

"What are we telling me?" Came Steve's voice as he and Danny came into view hearing his name.

The two cousins looked up and Kono smiled. "That you just missed Sam. She just wanted to check in but she had to go and pick Alfie up from day care. She said she'd pop by again after she's picked him up." She told him with a smile. "So any luck?" She asked quickly changing the subject.

"Steve shot the suspect." Danny stated looking to them.

Chin raised an eyebrow. "I take it he didn't want to talk."

"You would be correct in thinking that." Steve commented moving his hands to his hips before sighing. "We have no other leads apart from the mystery man no one seems to know and we can't find…"

"You think he's left the Island?" Kono asked looking to him.

"Well if he has he done it quick." Danny stated moving his hands into his pockets.

"Which means we have no chance of catching him if he's no longer here…" Steve grumbled before he sighed as his phone went off. Taking it out of his pocket, frowning at the number he then pressed the phone to his ear. "Hello?" He answered moving his free hand into his pocket. "Yeah speaking… she hasn't? No no it's fine I'll come get him now. Bye." Hanging up the phone he frowned. "That's weird."

"What?" Asked Danny.

"That was Alfie's day care…Sam hasn't turned up to pick him up."

Danny sighed. "You go I'll try and get a hold of Sam."

"That's odd that's where she was going straight from here…maybe she got caught up in some traffic?" Kono suggested looking to him.

Frowning Steve then shook his head as he then headed out of the palace. He had to go and pick up his son.

Taking his phone out of his pocket Danny dialled Sam's number, sighing as it went straight to voicemail before looking to Kono. "See if you can trace her…it went straight to voicemail."

Kono nodded before she typed in Sam's number. Looking to Danny she sighed. "It must be off…"

"Why the hell would she turn her phone off?"

"Maybe she didn't." Chin commented with a shake of his head.

"What's that supposed to mean?" Danny asked looking to him.

Kono glared to her cousin and sighed as she rubbed her forehead. There was no keeping it from him now.

"What's going on?" Danny demanded looking to the two of them.

Chin looked to Kono. "We have to tell him."

"Tell me what?"

Kono sighed as she took the note from her pocket and slid it over to Danny.

Danny frowned taking the piece of paper and opened it. Reading it he then looked to the two of them. "What's this?"

"That was sent to Sam three days ago…"

"The day she was supposed to be on the plane that blew up." Sighed Danny. "I take it Steve doesn't know?"

"She didn't want to tell him. Or you. She said Steve's still having nightmares about the whole thing. She just wanted to try and sort it herself."

"Sort it herself? Someone's out to kill her and she wants to sort it herself? What the hell is wrong with her?" He shook his head and looked to them. "When did she give this to you?"

"Today…before you arrived." Chin told him before sighing. "She's under the impression that it's Catherine…"

"Catherine? I thought she was long gone anyway from the lack of contact we've had from her…besides I don't think Catherine is even capable of this. She serves her country and all that. Surly becoming a terrorist isn't top of her list."

"No but getting rid of Sam is. And we don't know what she would do to get rid of her. Sam is a walking target…" Kono told him looking to him. "She wanted us to track Catherine's phone…keep an eye on her."

"And have you?"

"We haven't had chance yet."

"Do it." Sighed Danny shaking his head. "I'm going to kill her."

Kono nodded before she began typing away. As it came back blank she shook her head. "There's no trace of her either…"

"So what are we presuming?" Chin asked. "That Catherine has her?"

"We don't know that for sure. We don't even know if it's her to begin with…" Kono defended with a sigh.

"Pull up the CCTV from here…see where Sam went and what direction…maybe see if we can track her through the cameras on the street. See where she ended up." Danny ordered before sighing. "This isn't going to go down well with Steve."
