This is the sequel to my story 'Shadow Song'. Brennan and Booth are now in a relationship together when an old friend calls and requests their assistance. And so a new journey begins...

Over the next couple months, Seeley Booth and Temperance Brennan rebuilt the friendship and strong emotional bond that had endured the very trying times that had been dubbed 'Hannah's Reign of Terror' by one Angela Montenegro.

The two of them had also started something that so many people, both at the Jeffersonian and the FBI, had been waiting for them to start: they had started dating.

A few months later, they moved in together. Each gave up their respective apartment, for they had agreed that they each had to start anew; this relationship was not for one or the other: it was for both of them, together.

What they chose to do surprised everyone: they decided to buy the house once inhabited by Sergeant Katelyn Bell. They defended their choice: 'their' Rottweiler, Rafael, was comfortable in that environment, and it gave him a yard to call his own.

Another reason they chose to move in to Kate's old place was that it brought them a sense of peace; they both felt, on many occasions, that Kate's spirit was watching them, guarding them as she had promised. Being in her old home gave them the sense that she was always with them.

Another change that came about was a new friend from the Army: Sergeant Cory Hughes came to Washington, D.C., a few times a year. Every time he was around, he stopped by and visited Booth and Brennan. They always had a good time, laughing at the many stories Cory had about the crazy stuff he and Kate used to do, and just enjoying the common bond they had. They always missed Cory when he would go back to Fort Carson, and they promised to visit him sometime soon.

Booth and Brennan were doing very well together. They still had the highest solve rate in the entire FBI, and the mountain of work at the Jeffersonian was slowly being worn down with help from Brennan's many talented and dedicated interns.

It had been seven months since Kate had entered and exited their lives, seven months of change and renewal.

Another ordinary day was in progress at the Jeffersonian, where Brennan was working on yet another set of remains from Limbo...

Up to her elbows in old bones and tons of paperwork, Brennan started in surprise when her cell phone rang. "What now?" She grumbled as she took a quick step back and called, "Wendell or Clark, could you please take over here?"

Both interns came running as she stripped off her gloves and quickly said, "Thank you, I will be but a moment." She pulled the cell phone out of her pocket, flipping it open and answering with a terse, "Brennan."

They both watched as she turned her back, walking away a little as she said, "Hello Cory! It has been awhile. Booth and I were planning to take some time next month to come to Colorado...I'm sorry?"

Wendell and Clark went on alert as she tensed up, looking at each other as she said, "When did this happen? Has the FBI been notified?" They both waited until she said, "Of course. I will call Booth and let him know. You can expect us by this evening."

Brennan snapped the phone shut and looked at them both, chewing her lip slightly as she said quietly, "Please finish with the remains of this soldier and see to it that he is sent to the Civil War section of Limbo. We will have to finish with his identification later."

It was Clark that took the initiative, and he asked hesitantly, "Is something wrong, Dr. Brennan?" She looked at him calmly as she replied, "Yes. Sergeant Hughes, our Army friend from Fort Carson, believes that his unit just uncovered several more victims of The Watcher from his time in Colorado. He asked that Booth and I come to examine them and try to make a determination on who they are and whether or not The Watcher killed them."

Wendell, encouraged by Clark's boldness, asked, "And if they aren't?" Brennan looked at him, her gaze razor-sharp as she said softly, "Then we have a problem."

Booth came out of Interrogation One, dragging his suspect by one arm as he gave him a healthy shove towards another agent. "Take him down to booking, Justin." Booth grunted. The other agent grabbed the man and led him away as Booth rubbed at his eyes tiredly, heading towards his office with a world-weary sigh.

Man, when is this madness going to end? For the last week, Booth and his top three guys had been stuck with the daunting task of interrogating over three dozen men recently arrested in a drug-smuggling ring. They were processing the detainees through like cattle, and they still weren't done.

Just as he got to his office and kicked the door shut, his cell phone rang. "Good God Almighty, what the hell is it now?" He asked, his eyes drifting to the ceiling as he walked around his desk, falling in his chair with a thud and unsnapping his cell phone in the same movement.

"Booth." His voice, usually a smooth, medium baritone, now resembled the guttural grunt of a thirty-year chain-smoker.

"Hey Booth, it's Brennan." His partner's voice in his ears was a soothing melody that immediately cleared the fog from his gaze and lifted his tired spirit.

"Hey Bones! What's going on?" He asked, his voice returning to normal immediately. Then his heart started racing when she stayed silent about five seconds too long. "Bones? Talk to me. What's wrong?"

He sensed her turmoil even before she spoke. "I got a call from Sergeant Hughes. The soldiers out at Fort Carson found something. They believe that it is leftovers from when The Watcher was stalking the soldiers out there, but they want us to come and confirm. I told Cory we'd be there by this evening at the latest."

Oh God, not this again. Seven months and we're back to this piece of inhuman slime again. Booth thought as his heart sank. I don't know if Bones can go through this again. The Watcher got too close to us too fast; it really shook her up when Kate died. She can't go through this again...and neither can I.

This time, it was Booth that stayed silent too long.

"Don't worry about me. What's done is done. Cory needs us now. The least we can do is go and check. Best case, they found some ancient burial ground. Worst case, we have another Watcher on our hands. We won't know until we get there." Brennan said quietly.

Booth sighed heavily and replied, just as quietly. "When you put it like that, I don't see what choice we have. Give me thirty minutes to run this through Hacker. I'll be there to pick you up within the hour. Go ahead and find us a flight; we're going to Fort Carson."
