Booth and Brennan left the Jeffersonian. Brennan was very upset about all of this.

Brennan, "She is so unreasonable! It doesn't make any sense why she would say those things to me after last night!"

Booth, "She was angry."

Brennan, "And that makes it ok for her to say such hurtful things to me?"

Booth, "No, but you hurt her too."

Brennan, "So now you are taking her side?"

Booth, "No, I am just saying that you both hurt each other."

Brennan, "Well I don't see how I hurt her."

Booth a little surprised, "You told her that her brother isn't her brother."

Brennan, "Well he isn't!"

Booth, "In her metaphorical heart, he is her brother."

Brennan, "She didn't have to get so upset."

Booth, "What if someone told you that Russ isn't your brother?"

Brennan, "But he is my brother."

Booth, "Do you want to ask Sweets about this?"

Brennan, "Actually I would."

Booth called ahead and Sweets made an opening for them. Sweets had actually made his schedule more flexible knowing that he might have many more sessions with both the sisters.

Sweets, "Ok start with the beginning."

Brennan told him how she thought everything was going well and all about last night.

Sweets, "I don't see the problem."

Brennan, "Well I went into the lab to tell her about my doctors appointment and there she was at the table with a music player in her ear singing with Fisher."

Sweets now childishly curious, "What song were they singing?"

Brennan a little confused of why he had interrupted her to ask that, "Disturbed."

Booth adding, "Down with the sickness."

Sweets, "No way! Really?"

Brennan, "Can I continue?"

Sweets, "I am sorry Dr. Brennan, please continue."

Brennan, "So I was scolding…"

Booth interrupted, "Yelling."

Brennan gave Booth a dirty look and continued, "She was telling Fisher and Booth how her brother loves this song and I corrected her telling her that he was her cousin."

Sweets, "Ahhh. I understand."

Brennan started to tear up, "So she told me he was more of a brother to her than I was a sister."

Sweets said simply, "She was right."

Brennan now with tears rolling down her cheeks and angry, "How can you say that? Genetically speaking…"

Sweets cut her off, "It isn't about how many genes you share. It's about the bond that was formed when she thought she was genetically his sister. She grew up knowing him as her brother and the bond had formed."

Brennan as if a light bulb went off in her head, "Oh." (she said modestly)

Sweets continued to speak, "You threatened her sense of security. You both have already been put through the emotionally ringer with family issues and you…"

Brennan, "Made it worse?"

Sweets, "Not necessarily made it worse, but maybe Dr. Richards is still trying to process her feelings about this same issue."

Brennan, "So what do I do? Apologize? I am not going to apologize about getting upset about them listening to that music player at work."

Booth, "It's called an I-touch Bones."

Sweets, "Yes apologize for the cousin comment, but wait until tomorrow, so you can both calm down."

Brennan, "I can apologize at work tomorrow. But I think she should also for saying those hurtful things."

Sweets, "When you apologize to someone it's best not to expect anything in return."

They left Sweets office and they saw Hall in the hallway.

Hall, "Bren you look upset."

Brennan, "I got into a fight with Rayah."

Hall, "But I thought last night went well?"

Brennan, "It did, but this afternoon was just awful."

Booth, "It was a sister type of fight. I have had the same arguments with Jared."

Halls, "Ooh, my sisters would get brutal!"

Brennan still looking sad, so Hall spoke again, "I will talk to her for you ok?"

Brennan, "I would appreciate that."
