A/N: Thank you all for all the feedback, I've gotten bad about not replying back to all of the reviews that you all have sent me and i'm so sorry about that! I appreciate all of the feedback. Please overlook my stressed out, final-reviewing, life for the moment and keep them coming! Thank you again!

Booth looked at her, happy to see her smile, "She said her name was Brennan, you didn't take Sully's name?"

She shook her head, "No…he's not her" she let out a breath, "…we never married," she thought about how to tell him this, "Her father left before she born, he didn't even know of her existence until recently. And he still doesn't know he's the father." It wasn't a lie, just didn't tell him the exact truth.

"Sully left? Left the FBI all together or just you?" he didn't like talking about him and their relationship but if he left her, Booth felt the need to hurt him.

Brennan sighed, Booth didn't understand, "He's not Aud … yes Sully did leave the FBI…but we broke up. I broke it off before she was born," she paused, "He found out about…" she looked at him with widened eyes.

"Oh…how?"

She just noticed that Russ was still standing behind Booth, "Russ you can sit down."

He shook his head, "No, I think I'll go draw with Audrey."

Booth looked between the siblings, her eyes widened as he tightened his face as if they were trying to tell each other something. "Russ…"

"Temperance." He paused, "I'm going to go draw; you two need to talk."

Once Russ had disappeared from his view he spoke, "What was that about?"

She closed her eyes and then looked up at him, "You seem to think that Sully is the father…he's not…"

"Oh, does she know who her dad is?" he asked, hoping he knew whom it was but not wanting to ask her directly.

Brennan looked down, "We have pictures but no, she doesn't know he's her father. Or at least I haven't told her, I think she can tell though." Booth looked at her in question, and decided for now to let the coincidence of pictures slip. "I talk about him all the time and I know I smile too often when I speak of him." She paused and smiled, "And her father has this uncanny skill at reading people, she inherited it." Brennan hoped that he understood now, "She already knows way too much about everyone." He nodded, smiling, as she continued, "And…the reason I ended it with Tim was because, I told him about what had happened between us…" she paused gauging his reaction, "he was still our corresponding agent until…he found out I was pregnant."

Booth shook his head, "Why? What happened? He didn't think she was mine did he?"

She looked up at him, with a sort of sad smile, as she recalled that day.

Flashback…

She was standing over the remains of their current victim, not too long after she had shared her surprising news with Angela, when Sully touched her back to get her attention. She stood upright, Sully then asked, "I know a man should never ask a woman about her weight, but are you okay… you look like you've gained a little in your face…"

Brennan looked at him incredulously, planning on playing it off and him not find out when Angela, who must have forgotten that she was the only person in the lab who knew of their friends medical condition, spoke, "That's just baby fat!" however as soon as the words were out of her mouth she realized they weren't supposed to leave it.

Brennan squinted her eyes shut and awaited the comments. "Baby fat?" a voice spoke.

"As in pregnant…?"

Then Sully's voice spoke for the first time, angrily, "I guess I don't need to ask who the father is, do I?" Brennan opened her eyes in time to see his retreating back going towards her office.

"Tim!" she ran after him, no one seemed to understand, especially not Angela she thought Sully was the dad. Once reaching her office she saw him sitting on her couch, "How do you know it's not yours!?"

He looked up at her, hope evident in his eyes, "Is it?"

She straightened her shoulders, "I just got the test back this morning."

He eyes locked with hers for a mere second longer and then he looked down. Standing he sighed, "Are you going to tell him?"

"That's why he left, he wasn't the father and it had been awkward anyway… so…" she coughed, "I'm not one to sleep with the next random guy I see … I only slept with…" she was mumbling and in the end couldn't make complete sentences.

He touched her hand and smiled, "Does anyone else know?"

Brennan sighed, "Russ and Sully are the only ones who I've told. That's why she goes by Brennan,"

"So you didn't keep your last name with her?"

Tempe looked at him with tears forming in her eyes, shaking her head, "I couldn't help but hope her father would come back. On her birth certificate her name is Audrey Christine Brennan Booth."

I almost left it rigth after the flashback, and made you beg for the last bit... but then I remembered how rude I'd been about not replying back so, since I couldn't get you Booth and it's so very hard to get cookies through the computer screen and over the web to the right places, I settled with this conclusion. LOL. Please tell me what you think.
