Author's note: Thanks for all the reviews!

"How long have you known this Peter?" Booth asked as he escorted Brennan and Isa out of the building.

"You can't seriously think that he is a suspect?" she rolled her eyes as she held Isa's hand.

"Hey you've cleaned up pretty nice." Brennan was indicating the missing earring, his clean-shaven face, and crisp Armani suit.

"Yeah, well, FBI has a policy on that. What's your favorite ice cream Isa?" he directed his question to the five-year-old skipping happily.

"Chocolate chip cookie dough. That's Peter's favorite too."

"You and Peter must really get along, huh?"

Isa nodded and then shrugged her shoulders. "Sometimes he too strict for his own good you know. I think he needs to loosen up."

"Amen." Booth said.

"If you're implying that Peter would ever hurt me or Isabella you're wrong. In fact he is planning on adopting Isa…" she said not realizing the impact of her revelation until the words left her mouth.

"He wants to what?"

"Adopt me. Since I don't have a father." Isa answered. "It's kinda nice if you think about it."

"Over my dead body." He said through gritted teeth.

"Booth!"

"'Booth' What? No way is that gonna happen!"

"You don't like him very much do you?" Isa asked butting into the conversation.

"Isa it's very rude to interrupt an adult's conversation." She chided.

"Wait a minute I thought Peter was your ex?" the recognition of his name dawning on him.

"Peter St. James was my ex, this is a new Peter."

"Way to play it safe Bones." Brennan opened her mouth to respond but the shrill sound of a bullet making contact with a glass window rang through the air. Isa screamed as Booth lifted her into his arms and grabbed Brennan throwing them against the side of a random car. He removed his gun from its holster and shot a few bullets through the windows to open it and began shooting at the car that began to speed off. He sighed as the vehicle fled out of sight and cursed under his breath. Booth turned his attention back to Brennan and his daughter who were breathing just as heavily as he was. Brennan's crystal blue eyes bore into his, he could clearly see the fear in them.

"Are you alright?" He offered a hand to her that she gladly took. Brennan nodded mutely as he helped her and Isa to their feet.

"How about you?" he dropped down to his knees so he was eye level with the shaken little girl.

"Were they trying to kill mommy?" she asked as her bottom lip began to quiver. His heart broke as she wrapped her tiny arms around his neck. Booth sighed and picked her up rubbing her back softly.

"I'll never let that happen." He whispered.

"Damn it Temperance. You could have been killed!" Peter yelled walking back and forth in their kitchen.

"We're fine Peter." Brennan reiterated stirring the bubbling contents in the pot.

"I knew this was a bad idea having this Booth follow you around."

"If it wasn't for Booth I would have caught a bullet to the skull. What do you say to that?" she said turning around to face him. Brennan knew there was more to this. Peter obviously felt threatened by Booth's presence especially since he was Isabella's father and quite frankly she wasn't in the mood to stroke his ego.

"Whatever, Booth saved my life and I am eternally grateful." Peter sighed and his hands came to rest on her hips, he drew her to him breathing in the flowery scent of her hair.

"I don't know what I would do if anything happened to you too. I love you." His lips found hers pressing a loving kiss to them. He pulled back his eyes searching her.

"I…love you too Peter." Brennan repeated. He smiled happily and continued the conquest of his lips on her neck.

"Ahem." Booth cleared his throat as he and Isa appeared in the doorway of the kitchen holding hands.

"Geez can't you guys cut that out. We have company." Isa said indicating Booth. "Is dinner ready yet. I'm starved." She huffed out.

"Um I'm almost done. Why don't you go wash up." Brennan said releasing herself from Peter's grip.

"I'll help." Peter offered.

"I'm a big girl." Isa whined as they made their way to the bathroom. She turned to Booth and cleared her throat. His stare made her uneasy as she brought down some dishes from the shelf. Brennan's shirt rose as she reached for an especially high shelf exposing her creamy skin. She couldn't help but notice that he zeroed in on her exposed taut tummy; Booth remembering what it was like to be intimate with her and shower her with kisses.

"It didn't take you long to move on." He said flat out. Brennan's movements stilled, a cup in her hand.

"That's not how it happened."

"Well then please enlighten me. Since Isa is mine than it wouldn't have been long after that you met him and began to plan your life together."

Brennan laughed coldly, "What makes you think that?"

"Peter told me he that he helped you give birth to Isa."

"That's a lie, Angela, Zach, and Hodgins were there. I didn't even meet Peter until Isa was two."

"Son of a bitch." He muttered sighing heavily. He turned around leaning both of his arms on the table in the kitchen. It was becoming clear that Peter was willing to say anything to make Booth feel like he had the better hand. Brennan exhaled noisily and walked up to him going on her instinct to touch him.

"What?" Brennan placed a tentative hand on his shoulder rubbing it slowly with her thumb.

"Peter told me all these things about how he was there for you and Isa when I wasn't. It really made me feel like crap. It was like he was Rebecca reminding me of all the time I missed out on with Parker. I mean I haven't even seen him ever since I came back. He must think I'm dead too."

"He has a way of doing that." She said shrugging her shoulders not knowing how to address the Parker issue.

"Why are you with him?" Booth turned around grabbing her hand in his. Brennan looked away trying to focus on anything but him.

"I couldn't…"

"You couldn't what babe?" he prodded circling a hand around her slender waist. Brennan's eyes reached his, her lips parted and poised to respond until the strident ring of the doorbell brought Brennan out of her stupor. She pulled back instantly, moving a stray strand of hair out her face.

"I'll get that." She responded softly. Booth moved aside to let her go answer the door.

"Isa someone's here to see you!" she called as the door closed. The little girl came running out and down the stairs to yell happily at the sight of her guest.

"Parker!" she shouted. Booth's head shot up at the mention of his son's name.

"No…" he thought shaking his head.

"Come on I want you to meet someone." She pulled the boy upstairs and into the kitchen. There, Booth came face to face with a young boy about twelve-years-old with yellow blond hair.

"Dad?" he asked hesitantly moving closer to Booth.

"Yeah, kid its me." He answered shaking his head. Parker leaped at Booth hugging him fiercely while Brennan lifted Isa into her own arms.

"Mommy you said that Parker was my brother because we had the same father." She pointed out.

"Yes I did." Brennan affirmed not knowing what she was getting at.

"Then that means Booth is my Daddy."
