Gibbs pulled up outside the hospital with Sam in tow.

"I hate this." Sam sighed as they walked up to the building.

"This whole situation isn't ideal." Gibbs agreed.

Sam shook his head, "Not that… Well, ok. That; but this! Again, someone has hurt my partner. G has been through so much in his life, and still people try to kill him. Why is it that just when I think he's found someone, someone to care about him, that he can build a life with them, they betray him?"

"We don't know that's what happened yet." Gibbs cautioned him.

"Who else could it have been?" Sam snapped.

"Calm down, We'll see how Callen is and check on Anna. But Hetty didn't want us to pick her up yet."

Sam smiled, "A little rope and hope she hangs herself?"

Gibbs nodded, "Maybe… Maybe not."

They walked into the building and Gibbs headed for the desk.

"Callen?" He barked.

"Sorry?" The nurse looked confused.

"Agent Callen, brought in half an hour ago by ambulance, possible Aconite poisoning."

"I'm sorry… Who are you?" She asked.

Gibbs produced his badge and showed her.

As soon as she saw it her tough attitude melted. "Ah… yes, NCIS. I'm sorry, Hetty Lange has been placing your agent here for years, we are under orders not to use the name you gave us, he's under his usual name."

"Usual name?" Gibbs asked.

"Greg Wolinski?" Sam asked, thinking he was using the same alias he used for his house.

The nurse shook her head, "No, we used his first alias, Gregori Mishnev. We rotate them on a regular basis, this one he's had since he was a teenager."

"You'll need to change that." Sam told her, "Is he awake yet?"

She shook her head and grabbed a clipboard, "Come with me." She stopped for a moment and hit some keys on the computer, "So back to Gary Lange then, next on the list."

"Take Mishnev off that list." Sam ordered, "It's not gonna be one he'll want to use again."

Not understanding, but having dealt with Hetty Lange and Callen in the past, she nodded and did as she was asked.

As they walked down the hallway the nurse filled them in.

"Mr. Lange has been sedated until we get the full results of the Tox screen, his wife is in with him." She said offhandedly as they walked to his room. "We are flushing his system with saline and as you know he isn't the best with either needles or staying in a hospital room if he can walk."

She smiled as Sam laughed. "You've dealt with him before. I see."

The woman looked at him, "On and off since his teens. I think I've spent more time worrying about him than any other patient." She admitted.

Sam smiled, "I'm Sam." He said, holding out his hand, she took it and shook it.

"Figured you were, the partner-come mother hen." She replied with an answering grin.

"How long have you been here?" Gibbs asked as they walked.

"Since '82." She replied, "Coming up to retirement soon."

She looked appreciatively at Gibbs, "I was a blonde until I met your Mr. Callen, now all these gray hairs, most of these I can attribute to him over the years." She reached a door and opened it. "I'll be down the hall if you need me." She told them and opened the door wider looking inside.

"Oh, you're awake?" She said in surprise looking at the man on the bed.

"You stuck me again Martha!" Callen groused with a small smirk as she walked in.

"You keep giving me gray hairs son." she adjusted his drip. "I'll be in my office if you need me sweetie." She ruffled his hair with a comforting look and turned to go.

Callen sighed, "Thanks, Martha."

He closed his eyes and laid back.

"God, my head hurts." He sighed, "Damn him."

"Who?" Gibbs asked, stepping closer to Callen noting that Anna wasn't in the room.

Callen shook his head, "No… It couldn't be him… He wouldn't…"

"Dammit Callen Who?" Gibbs growled.

"Marco." Callen glared at his friend, "He's the only one apart from me who could pull this off, he had access to all of us and the boatshed."

"DiNozzo is in custody, he can't hurt anyone. He's also not the only one with access to all of you. What about Anna?" Gibbs asked.

"NO!" Callen tried to get himself up, "You can't think Anna would do…"

"Think I'd do what, Callen?" Anna asked as she walked in with 2 cups of coffee and handed him one.

"I'll take that." Gibbs said and took the drink from her.

"That is Callen's drink, not yours." Anna said glaring at him.

"You poison that one too?" Gibbs asked.

"Poison? You think I poison Callen?" Anna looked shocked and stepped back hurt. "You think I poison you?" She looked over at him concerned as his gaze darkened.

"NO. No, I don't." Callen shook his head and stared at Anna, hoping that she wouldn't believe for one moment that he thought that of her. "Gibbs? What the hell?" He asked. "I already told you Marco has to be the one responsible."

"Anna was with all three of you." Gibbs stated.

"That's a coincidence."

"There's no such thing." Gibbs snapped back at Callen, he was angry his friend couldn't see what was right in front of him.

"Jethro!" Callen snarled, "You know me, you trust me. I was a member of The Calling. Yet you still trust me don't you?"

"Yes, but I know you."

"Well, I know her and I trust her."

Gibbs glared at the now angry woman. "Maybe you should try making decisions with your 'other' head."

"Dammit! GIBBS!" Callen sat up ignoring the pain the movement gave him. "You can't think that Anna will hurt me? Rule 51, remember?"

Gibbs turned away mad that Callen knew all his rules and had just used one on him.

"You think she couldn't?" Sam said, surprised, "You've fought with her before."

Callen smiled at the memory. Then he shook his head, "That's not the point Sam, Anna isn't responsible for this."

"Prove it."Gibbs said.

Callen lay back, the poison clearing from his system tiring him out.

"Marco was in the boat shed before he disappeared, right? Marco had the same basic training I had growing up; both of us were slated for…" Callen stopped and closed his eyes.

"What?" Gibbs asked as Callen stopped.

"It doesn't matter. Just check the bottle. You'll find his prints all over it, he's too cocky to have wiped them. Knowing him, he'll probably be bragging about how he did it."

Sam's phone beeped as Gibbs sighed at Callen's attitude.

As Sam stepped out, Anna moved to protect Callen.

"I know you don't know me or trust me Mr. Gibbs, but I love Callen and will never hurt him." Anna vowed.

"I am to trust your word on this?"

"I don't need you to trust my word. I know Callen trusts me." Anna said, her eyes flicking to the door as it opened again.

"I trust your word Ms Kolcheck." Hetty said as she and Arkady walked into the room.

"Callen. You are injured?" Arkady looked worried.

Callen smiled weakly, "I'll live." he sighed as he looked over at Anna who was still fuming at Gibbs and Sam.

"I did not hurt him Henrietta." Anna argued.

"We know that my dear." Hetty said. "I am sorry, I was the one who put the idea into their heads. I made a mistake and for that I apologize."

"Why would you do that?" Anna asked shocked.

"Because of my involvement with The Calling." Arkady admitted.

Callen turned, shocked as Gibbs moved his hand slightly towards his guns.

"You're with them?" Callen gasped as he moved to face Arkady.

The older man shook his head, his eyes narrowing in concern at the fact he'd accidentally caused Callen pain.

"No. I know about them. I would never be part of group like that." Arkady argued.

"How long have you known about them?" Gibbs asked.

"Long time." Arkady replied. "Is not important how long, just that I know."

"You knew what they were planning?" Gibbs asked.

Arkady shook his head, "No. I knew something big was happening. When Callen came to me and asked for my help to take them down I could not say no. I could not allow him to go in alone." He looked away, unwilling to reveal the pain on his face at the thought of losing Callen to The Calling again.

"Arkady?" Callen asked, wondering at the look on his face.

Before Arkady replied the door opened.

"Hetty, Gibbs. Marsino has escaped from the boatshed." Sam stated as he entered.

"When?" Gibbs looked beyond angry.

"About an hour ago, the guard went to check on him and discovered him missing."

"Marco will finish his mission." Callen said his hand involuntarily tightening on Anna's as he spoke.

"What mission is that?" Sam asked.

Callen gave a resigned laugh, "Right now… To kill me."
