In that second, Callen felt the pull, to be what he had been trained to be, a child of The Calling a son Alexei could be proud of. However, his inner self won.

"I will always be loyal to my family, and my team, and my agency." Callen picked up the cuffs and placed them in his back pocket. "I will make sure you get a doctor, Father. But I will be getting that list and handing it over."

For a moment Alexei looked angry, then his face went to disappointed and despite himself, Callen found himself shifting his stance over his father's stare.

"I should have guessed that you were working for them. You were always too willful."

"I have my own mind and I make my own decisions." Callen argued.

"You are my son and I will not say I am not disappointed." Alexei told him, "But I will always be your father, no matter how you see your team, I am your family. The Calling will always be a part of who you are. When you've seen the truth you can't walk away."

"Watch me." Callen snapped, "This is me… Walking away."

He walked out and slammed the door shut, leaning heavily on the other side.

"G, you ok?" Sam asked, walking around the corner.

"Is the doctor here yet, Alexei needs help." Callen told him.

"He's on his way Mr. Callen." Hetty said, walking up behind Sam. "Are you alright?" she asked softly, putting her hand on his arm.

Callen shook his head and walked into the main room, grabbing a yellow legal pad and a pen off the table.

He wrote down an address and handed the folded up piece of paper to Gibbs. "It's the house, Alexei's house. The information you want is in a concealed panel behind the couch in the living room. The wall is wood paneled and there is a small nick on the corner of the one that will move out if you press and click it. There's a red book in there. All the information you need is in it."

"So…" Deeks asked, "You with them or with us, 'coz, ya know it's getting hard to tell."

Kensi punched him on the arm, "Deeks!" she hissed.

"You're telling me you aren't confused ladybird?" Deeks asked.

"I'm giving you this information aren't I?" Callen snapped, he was tired, hungry and to be honest a bit confused himself.

Gibbs looked at the slip of paper, "Blye, Deeks. Head over there, see what's there and bring it back here." He ordered.

Kensi nodded and all but dragged Deeks out of the boatshed.

Callen sank down onto a hardback chair, "They don't trust me do they?" he asked as the other three sat down. Callen's eyes flicked from Marco to Alexei, on the monitor, he wouldn't… Couldn't look the others in the eye.

"They'll process G." Sam said as he handed him a bottle of water and a sandwich. "Eat." he ordered.

Not even thinking, which showed how tired he was Callen did as Sam told him. Anna walked over and started rubbing his shoulders.

"It is hard Callen, but they will understand in time." She reassured him.

"Alexei is in so much pain, he needs a…" Callen stopped and dropped his bottle of water as he watched Alexei collapse off of the chair.

He stood up and ran into the room with Gibbs, Sam and Anna hot on his heels and Hetty on the phone to the paramedics.

"Father!" Callen yelled as he ran into the room. "Please… no…" His voice cracked as he reached to feel for a pulse on the older man's neck.

"Callen…. Not…" Alexei closed his eyes and Callen hunched over trying to control his emotions as, the first person to treat him kindly, died.

"Paramedics are on their way." Hetty said as she joined them.

Glowering in fury Callen stood up, he looked at the tips of the man's fingers and checked his water bottle.

Grabbing the bottle, and making sure the lid was tight, he dropped it in front of Hetty, "You need to get that tested for Aconite." He growled.

"Mr. Callen?" Hetty asked, concerned.

"There is no way both Alexei and Roberto died from a heart attack. Someone else is involved and is taking out the family heads." He looked Hetty in the eye, "Someone is killing them, I know it. I need to talk to Marco again. We may need his help."

"G?" Sam stood in the doorway, "You said yourself that Alexei was sick. You said he had Cancer. But we were all here we watched him. He had a heart attack and you suddenly come up with the fact that not only has he been poisoned, but that it's linked to the DiAntonio's death? What makes you say that?"

"It's how I would have done it. Aconite isn't a readily available poison, but the signs on him are there. They were on Marco's father too. It just didn't register."

"How could Alexei have been poisoned here? No one has been with him except for Kensi, Deeks, Hetty and you. Out of the four of you only one… well, maybe from what you are saying two of you know how to kill someone like that and I know Hetty didn't kill him." Sam said.

Callen whirled on him, "I may have not betrayed you, but I would never... Never kill anyone without just cause and never him!"

"Never said you would G, but both Marco and Alexei had to ask you twice when you said about Roberto having a heart attack."

"I thought you trusted me?" Callen asked hurt, "Just because I can do it doesn't mean I would do it."

Sam put his hand on his shoulder to move him as the paramedics arrived. "I know that G. I do trust you, after all, not once did I think you were the mole, but you could have told me."

Callen walked over to the main room not wanting to watch as they took Alexei away, "Sam?" He started and walked over to the railing that looked out to the harbor, "How much do you tell me about your childhood? I mean your family?" He asked.

"I told you about my mother, growing up in Brooklyn, hell I even told you about the crazy cat lady aunt I have."

"Your point being?"

"I have shared my past with you."

"You told me bits, just like I told you."

"Yeah, but…. A terrorist group?"

Callen laughed sourly, "I didn't know it was a terrorist group at the time, it was a safe place… a… Fuck, Sam… I …" Callen pulled away the frustration rolling off him in waves, he turned and punched the wall, "This isn't fair! I didn't ask for what happened... I…" He swayed and Sam caught him.

"Get the hell off me!" Callen snapped.

"G?" Sam was confused at the abrupt change in his partner.

"Sam?" Callen's eyes were unfocused for a second, then he saw the empty bottle of water he had dropped when Alexei had collapsed. "Damn." He cursed, reached for the bottle and passed out.

"G!" Sam yelled as he dropped, "We need the paramedics out here. NOW!"

Sam moved as they rushed in to tend to Callen.

"What happened?"

"He was talking, then he just got angry and collapsed." Sam said, looking to where Callen's hand was reaching.

"I think he might have been poisoned, but I don't think he had enough to kill him, Aconite poisoning I think." Sam said.

The paramedic nodded, "We'll get him to the hospital and run a full tox screen on him."

"I'm going with you." Anna said as she stood back worried. "I'm his… I'm going." She told them and walked out with them.

Sam, Gibbs and Hetty watched as the ambulance rode off.

"I am worried." Hetty said.

"Why? I'm sure Callen didn't take enough of the water in to kill him." Sam reassured her.

"No, I know that Mr. Hanna, that's not why I am worried. I am worried because the one person with access to all three men who have been poisoned has just gone in the ambulance with Mr. Callen."

"You think Anna…?"

"Who knows Mr. Hanna, I believe a deeper look into Arkady Kolcheck and Anna Kolcheck may not be a misplaced use of our time however, do you?"

"I'll go to the hospital," Gibbs told them, "Let me know when you hear anything."

In the ambulance, Anna held Callen's hand stroking it softly with her thumb as the paramedic took information from her.

"Soon, Callen… Soon." She whispered as the ambulance whisked it's cargo closer to the hospital.
