A/N: A season 3 AU diverging from after Chuck vs. the other guy. People have een asking me for a darker one so here is my attempt. Still don't own nor make any $ from Chuck.

Uniondale prison is a maximum-security prison located under the hot desert sand of Arizona. It is the ultimate holding area for the nations unofficial prisoners, the ones that the nation refuses to admit exist. It was one of the most secure facilities on the planet, and it was where Major John Casey was waiting in an interrogation room for the prisoner to be brought in. He was not a man usually susceptible to emotions, but this was a unique situation and he found himself conflicted. He had a personal history with this prisoner, and even though he felt the anger of betrayal, he couldn't help himself from feeling a little sympathetic as well.

"Major Casey, prisoner #1123 is here. Please stay clear of the door," came a voice over the intercom.

"Roger that," Casey said as he cleared the door.

The door opened and three burly guards in olive drab uniforms escorted the prisoner to the chair in the middle of the room.

"They won't be necessary," Casey said, as one of the guards was about to anchor the prisoner's leg shackles to the floor.

"Are you sure sir," the guard asked.

"You won't give me any trouble will you," he asked the prisoner.

The prisoner acknowledged no.

"Very well sir. We will be right outside," the guard said as they departed, leaving the room in silence.

Casey looked at the person before him an it did not resemble the person that he saw just a few days ago. He saw the pain in the face, hunched posture, and dull eyes and knew that the prisoner was broken.

"Well I am here as you requested, what do you have to say for yourself?"

"How was it," the prisoner croaked, voice thick with emotion.

"He was buried with full honors."

"I should have been there Casey," she said as the tears came.

"Yeah. You're probably right," he replied.

The room fell into silence with the exception of soft sobbing from the prisoner.

"Casey I need to ask you a question about Paris."

"What is it," Casey replied.

"Did he suffer?"

He felt the anger rise up inside of him at her question. He tried to push down his feelings, but the bitterness of the entire situation was just too much.

"What do you want to hear Walker? Why do you even care? You left him when he needed you the most," Casey fumed.

"That's not fair Casey! I left to protect him; I thought that if I stayed I wouldn't be able to save him. I thought he...he would..,"

"Die? Ironic isn't it Walker," Casey said as he stared her down.

"Casey please! I loved him," Sarah sobbed.

Casey fought down the anger that he felt at the woman across from him at the moment.

In truth he wasn't angry with her, as much as he was angry at the situation that she put herself in. She was a good agent and didn't deserve what he knew was coming to her, but she made her own bed and would now have to lie in it.

"Walker I believe in being honest with you, so I will tell you the truth. However, I would suggest that you ask yourself if you really want to know the answer, before you ask that question again."

Sarah could sense from his tone that she would not like the answer, and the remaining strength she had quickly began to dissipate. Tears seemed to erupt from her at his statement, and Casey was certain that she wouldn't be able to handle the truth, but he owed this to Chuck. Chuck deserved to have his loss felt, and maybe this way Sarah could realize just how much he meant to her.

Sarah looked at him with eyes pleading and silently shook her head, begging him to answer the question.

"Let him rest in peace Walker. It's over now, he didn't suffer."

Sarah held her head in her hands and felt the bitter sting of regret. What happened to him was her fault and she knew it, she may have not pulled the trigger, but she was responsible.

"Don't beat yourself up too bad Walker, Shaw played us all," Casey said as he could see her pain.

Shaw that son of a bitch! Sarah thought, that was her biggest mistake. Chuck was killed because of her actions, if she never killed Shaw's wife then none of this would have happened.

"He didn't fool Chuck! He tried to warn me and I didn't listen. I was such a fool," Sarah said sadly.

"What's done is done Walker. You can't have it back."

"I want him back Casey!"

"I'm sorry Sarah. Chuck Bartowski is dead."

The words caused a sudden pain in her Chest as if someone had just ripped her heart out.

"Your deposition is coming up tomorrow and I have been asked to speak on your behalf," Casey said.

"By who," Sarah asked through the tears.

"Bartowski," Casey replied.

"Chuck? When did he...,"

"On the way to the hospital that night in Paris. You were unconscious, and Bartowski was fading."

Sarah slightly moaned at the mention and felt her heart ache exponentially increase.

"His only concern was for you. I told him what would most likely happen after the smoke cleared from everything and they took you into custody. He never believed the things you were accused of and asked me to speak for you at your hearing."

Sarah smiled slightly at Chuck's concern, but suddenly that made her fell his loss all the more.

"Do you believe me Casey? I didn't do what they say I did," Sarah said.

"I warned you to not ask questions that you don't want the answer to Walker. I owe Bartowski and that's why I'm speaking for you, it doesn't matter what I think."

"Please Casey it matters to me," Sarah begged.

"I really don't know Walker, but what I do know is the bullet didn't hurt him as much as when you left. We are done here," Casey said as he got up from the table and the guards came back in.

Sarah hung her was and cried as Casey exited the room, leaving her alone to face the unknown.
