Booth didn't know what to do, feeling the panic settling in on his body, he was too stunned to even move. He felt as if he had punched in the stomach as hard as possible, and knew it was quite possible that he could throw up right then and there. His partner was on an undercover assignment, and he had no knowledge of it? She was in the middle of a club, dancing and intermingling with these men of low moral fiber, and stunk of too much cologne and unprotected sex.

He turned on his heel and walked toward the table that he had left Hannah at, and watched her eyes light up when he approached the table, though they darkened the moment she saw the look on his face. "What's going on?" She asked immediately, her hand reaching for his arm, he pulled it away and grabbed his beer, taking a big swallow from the glass, he slammed it down on the table.

"We have to go." He stated in a very serious, very stern voice as he reached for Hannah's hand. She pulled it back and glared.

"What's going on, Seeley?"

"We have to go." He replied again, this time more insistent. "Just believe me, okay?"

"I want to know why we have to go. Did something happen with Parker?"

"No, it's Bones, we have to go."

"Temperance? What's going on with Temperance?" She asked, allowing him to take her arm as she led her through the crowd toward the door.

"I'll explain outside." He said loudly over the music as he helped her from the club slowly. They pushed their way out onto the street, and she turned around immediately, watching Booth look frantically around.

"What's going on, Seeley? What's wrong with Temperance?"

"She's in there." He said, only now realizing that he's out of breath. "I thought I saw her when we first got here, and I confirmed that she was there. She's undercover." He said, lifting the phone to his ear as he ushered Hannah away from the club, he looked around to make sure that no one could hear him. He waited as he walked with Hannah down the sidewalk. "Charlie, I need you to get me some information." He said, chattering into the line to the other agent, he waited for a moment and thanked him, then hung up the phone.

"She's undercover, I thought that you were partners?"

"We are, which is why I can't figure out what the hell she's doing in there." He said, looking around, he spotted a gray van on the side of the road close to the corner, parked among the other vehicles for people that were attending the club. "I'm going to find out." He said, holding Hannah's hand, he started to pull her along down the street, her feet slamming into the sidewalk behind him as he nearly literally dragged her toward the van.

"Seeley, where are you…"

"Just… keep it down for a second, okay?" He said, approaching the van, he immediately recognized that it was a government issue vehicle, and he began to slam his fist into the back of the van.

"Seeley, what are you…?"

Suddenly, the door opened, and Booth didn't even wait for a response, he just climbed into the back of the van, pulling Hannah along the way.

"What the hell are you doing here?" Booth said to the agent, who was now focusing on the monitors in front of him, there was a camera moving through a crowd of people. "Is that Bones?" He said, watching the agent ignore me. "Listen to me! That's my partner in there… is she in danger?" Booth asked, frantic, he grabbed the other agent's shoulder and he turned around sharply, pulling one headphone off his ear.

"She's going to be in danger if you don't shut up and stop making a damn scene, Booth."

"What's going on?" Hannah asked, looking around at all of the equipment, she wasn't unfamiliar with the devices, but she was thoroughly confused as to why they were staking out the club.

"For having such a good looking girlfriend, you were dancing pretty comfortably with my target."

"Target?" Booth asked, focusing on Brennan, he watched the camera move through the crowd, moving methodically. "Why the hell do you have my partner working with you, Willis?" Booth asked angrily.

"She doesn't just work for you, Booth. She works with the FBI. We needed a civilian."

"She's not a civilian, she's a forensic anthropologist." Booth grunted as he watched the other agent look at the screen. "And she doesn't work for me, she works with me… what the hell are you doing, Bones?" He asked, as if she could hear what he was saying, he watched the motion on the camera.

"Yeah… he's here. Don't worry, he hasn't yanked the headphones off my ears just yet." The agent chuckled.

"You danced with her?" Hannah asked, but Booth's eyes remained on the screen. There was no time to argue about such trivial things, his focus was not on his girlfriend.

"What's the assignment?" Booth asked, getting a folder handed to him from the agent, he looked over it quickly. "What the hell, Willis? She's replacing your partner?"

"My partner is in the hospital, I needed someone for this assignment."

"Your partner was shot in the line of duty, she was shot on a goddamned undercover assignment!" Booth exclaimed, slamming the folder down on the console. "Get her out of there now!"

"Seeley, I think they know what they're…" Hannah said, feeling his arm brush her away as he leaned over the other agent.

"Get her out of there now, or I will go in and physically drag her out of there."

"She's signed the forms, Booth. She works with the FBI. You two have gone on plenty of undercover assignments." Willis said, glancing back at the other agent, he turned his attention back to the cameras and mumbled something into the microphone to Brennan. "That's right." He said into the microphone. He looked up at Booth. "She said get lost."

"She didn't say that… let me talk to her." Booth said, reaching for the headphones.

"Booth, I swear to God, if you fuck up this assignment, you're going to end up suspended. Just cut it out, let her do her job." Willis said calmly.

"Seeley, we should go… You don't want something to happen because you interfered."

"I am not leaving this van until the assignment is over." He said angrily, still glaring at the screens as Brennan worked her way toward the back room.

"Seeley, we should go." Hannah said firmly, catching Booth's eye for a moment, she looked angry, and his face was showing that he clearly did not care. He heard Willis talking quickly into the microphone, and the camera had whipped around quickly, showing a bit of a panic occurring in the club. People were moving quickly past Brennan, and Willis was trying to get her to respond, when suddenly a large explosion shook the van, the sound was loud and disruptive, and the screens in the van went white with snow.

"What just happened?" Booth asked, glancing to Willis, whose face was white with shock. "Fuck, Willis! What just happened?" Booth asked, grabbing his shoulder, the man said nothing, and without another word or thought, Booth was out of his van and running as quickly as he could toward the pandemonium of screaming and burned people who were exiting the club in a mass exodus, trampling and shouting, fighting for air and help, Hannah and Willis watched as he fought his way through these people toward the building, as sirens screamed in the distance.
