A/n: Here's another chapter, you can thank my inner muse. Because I updated twice in one week, there probably wont be another chapter till I'm done with school and have updated my other in progress stories first, also because of the violent nature of the cases I will be changing the rating to T and possibly M just to be safe, enjoy.

Chapter Four: Sometimes You Can't Forget The Past

"What are you doing here?" Brennan asked though she had a feeling she knew the reason for his return after nine years.

"Didn't they tell you, I'm your new partner." Sully said grinning.

'' I already have a partner, you may be the new FBI liaison, but you are not my partner,excuse me.'' Brennan said starting to walk away.

'' Tempe,wait, can we talk?'' Sully said walking after her.

''It's Dr. Brennan, and unless you want to talk about the case there's nothing to talk about.'' Brennan said clearly angry, she wasn't expecting this, expecting him to come back into her life, especially not as a partner replacement.

'' I can see you're upset,but you need to know why I came back,why I took this job.'' Sully said.

''And why is that?''Brennan asked almost afraid to hear the answer.

''Because...'' Sully began ,but was interrupted by Dr . Marshall , who approached them.

" Ah, I see you've met our new FBI liaison Agent Sullivan." Kelly said.

"We've met before, excuse me, I need to confer with Angela on something." Brennan said taking the chance to walk away.

"Dr . Brennan, when your done , I'd like to speak with you a moment in my office." Kelly said.

" That's fine." Brennan said and continued on her way. Sully turned to Kelly once Brennan was gone.

" I thought you said , she'd know I was going to be her new partner, before I came in." Sully said frustrated.

" I didn't get a chance to talk to her Agent Sullivan, if you hadn't noticed we're in the middle of a big case." Kelly said not appreciating his tone.

"Well, me and Tempe....Dr . Brennan had a history, I wouldn't have taken the job if I knew she wasn't ok with it." Sully said.

"Your working together isn't going to be a problem is it, because I can ask for someone else , if you two can't work together." Kelly said.

"No...no it's not a problem, I'll make it work,let me know if your team has found anything that can be linked to the Mercado family " Sully said.

"I'll be sure to do that." Kelly said then walked away.

Sully sighed as he thought about his interrupted conversation with Brennan,he was actually a little bit relieved when Dr . Marshall interrupted them, before he could say something stupid like the real reason he'd accepted the job. He could kid himself all he wanted , but deep down he knew exactly why he was back, why he had taken the job, whether he wanted to admit it to himself or not, he only hoped he could keep his true feelings for her to himself.

"Your kidding, Agent Sullivan, as in Sully, the guy you let sail off into the sunset, is your new partner." Angela said shocked after Brennan told her.

"Yes, he said he wanted to tell me why he came back and why he took the job, but Dr . Marshall interrupted us before he could explain." Brennan said.

"Huh, what do you think he was going to say?" Angela asked somewhat curious.

"I don't know, and I don't want to know, I love Booth now,we've got a family." Brennan said.

"I know that sweetie, you should make sure Sully knows that too,especially if he came back because of you." Angela said.

"You really think that's why he came back?" Brennan asked.

"Why, you don't want that to be his reason, do you?" Angela asked looking confused at her best friend.

"No, of course not, I just...I don't want to have to work with him, and I don't think Booth would like it either." Brennan explained.

"You've got that right, even guys like Booth get jealous, regardless if there's something to be jealous about or not." Angela said.

"We should probably focus on the case, plus Dr . Marshall wants to see me in her office, I shouldn't keep her waiting long." Brennan said changing the subject.

"So what did you want to see me about, other than the Sully thing?" Angela asked seeing that her friend needed to focus on something else.

"I was wondering if you identified remains number twenty-three, I noticed a pre-mortal fracture that they others didn't have." Brennan said.

"Yeah, I just identified her, Sarah Lawson, she just turned twenty-four when she disappeared,that was six months ago, why do you ask?" Angela said.

" If I'm right shes not a victim of the Mercado family, that means we're looking at two separate cases." Brennan explained.

"There's something else, isn't there." Angela asked seeing the wheels turning in her best friends head.

"It's nothing..." Brennan said not wanting to say her suspicions out loud.

"It's not nothing, whats going on Bren, tell me." Angela asked knowing her friend was worried about something.

"That fracture, I've seen it before...I think...I think, Sarah Lawson is a victim of the D.C. Slayer." Brennan said the color going out of her face.

"Oh my God, you think he's back!" Angela said her face paling as well, she never thought she'd hear that name again.

Five years earlier her and Booth had discovered the body of a missing twenty-four year old , who had been kidnapped , raped and killed by the killer, who came to be known as the D.C. Slayer. Brennan and her team had caught onto his trail after four more bodies were discovered, when he kidnapped her and Angela, thankfully Booth was able to find them before the killer could do to them, what he had done to his other victims.

When The FBI found out where Angela and Brennan we're being held, they'd stormed the place, but the killer was already gone, the killings had stopped and the FBI had gotten a tip that whoever was killing those girls had moved on and left the city,if Sarah Lawson had been killed by the D.C. slayer that meant that he hadn't left or that he was back and now that they'd found another of his victims, Angela and Brennan as well as their families could be in serious danger.

A/n: So I got inspired again , the story has a mind of its own, I'm kinda playing each chapter by ear, this is definitely not the direction I had in mind when I decided to write this sequel,it was supposed to be more of a fluff piece, but this new direction does create what I think will be an interesting storyline full of drama, hope your liking the story as always, reviews/suggestions/constructive criticism are always welcomed, I'd love to hear what more of you think, even if its construct criticism , because your reviews help me grow as a writer, so please let me know what you think and if you write as well I will gladly do the same for you ,hope ya'll liked the chapter, thanks for reading.
