Tracy Keller found the secret entrance she had been told about by one of her criminal buddies and quickly, but quietly, entered the dark tunnel. She closed the grate behind her and climbed down the steel rungs used as stairs, being careful not to slip on the recently soaked bars. Once she was at the bottom, Tracy pulled a flashlight from her waistband and flicked it on, glad when the old thing started right away. She turned around in a full circle, making sure she checked every little crook before she moved forward. The tunnel was still wet from the rain that afternoon, so Tracy was careful as she walked; she didn't need to trip and stuff everything up. This 'mission', as she called it, was too important. Her best friend was in need of her help.

After walking for what seemed like hours in the cold, dark tunnel, Tracy came to a fork in the road. She could go left, find the other end of the tunnel and get out before she did anything illegal, or she could continue with her plan and take the right side, following it until she got to the manhole she needed. She hesitated for a moment, but her gut was telling her to keep going, so she did. She turned to the right and continued walking for another half a mile. When she stopped, there was a steel door above her. A short ladder was laying on the floor of the tunnel nearby and Tracy grabbed it. She stood the ladder underneath the door and climbed it, reaching her hand up when she got to the second last rung. She took hold of the handle and pulled. The door swung down on the opposite side of Tracy, revealing a dark tunnel with steel rungs protruding from the side. Shining her flashlight into the tunnel above her, Tracy was glad to see someone already climbing down. The plan had so far gone off without a hitch, and Tracy was determined to see it through.

"It's about time," said the woman now climbing onto the ladder.

"I missed you too," said Tracey. She shut the door and followed the woman down the ladder. On the ground, they hugged, and when they pulled apart, anyone watching them could have sworn they were seeing double.

"Thank you for this Tracy."

"You are my best friend, my twin sister. I would do anything for you, Zoe."

Tony walked into NCIS, a big smile on his face. The last three weeks had been slow, what with him being stuck on desk duty while his ribs healed. But all that was changing this morning. Tony was late for work, but he knew Gibbs wouldn't be angry. He had told him the night before that Brad had called to reschedule his appointment because he was going to be out of the state on business, and the only available appointment was in the morning. Gibbs had told Tony to go to the appointment and then come to work. At the appointment, Tony, who had been worried that three weeks wasn't long enough for him to completely heal, had been surprised. After several x-rays and a lung exam, Brad had declared that the two ribs had healed completely and that Tony's lungs had healed properly to the best they could hope for. He had given Tony the all clear to go back into the field, and that was why Tony was currently sporting a massive smile that lit up his whole face.

"How did the appointment go Tony?" asked Gibbs just as Tony sat down behind his desk.

"Great. Brad is letting me go back to field work. My ribs have completely healed and my lungs are as good as can be," said Tony happily.

"I'm glad. We've missed having you out there."

"So, can I join you today?"

"You can. We have a new case."

"Great, let's go." Tony stood again and picked up his bag.

"Tony, wait. The case came from Leavenworth. Prisoner escape."

"So?"

"So... the prisoner is Zoe Keates."

Tony's face dropped. "She's out there somewhere?"

"Unfortunately. You don't have to work this one if you don't want to."

"I'm good. Let's go while the trail is still hot." Tony walked to the elevator, but his earlier mood had soured.

Gibbs gestured for the rest of the team to follow and they, too, walked to the elevator. All three were worried about Tony. He had only just healed from Zoe's last attack; what would happen if she got to him now?
