As they made their way up to the entrance of the preschool, she thought of what to say to Christine. After all it wasn't everyday that she met her sister she didn't know she had. She decided to go with the truth, seeing as she didn't believe in lying to children. Brennan had told her that Christine knew all about what happened between her mom and dad. Even though she was six, Chris was very intelligent. As they signed out Zac, Zooey and Chris, the children came running to them.
"She's new." Chris said, she had Brennan's sense of bluntness.
"Yes, Chris, I think I'll let her do the explaining though." Brennan said, by this time Zooey and Zac were enticed by Summer. She looked like their mother and wondered if it was like a long lost aunt or someone.
"Christine, I'm your sister. Well half sister actually, but anyway I'm your fathers daughter. You see my mom got killed and I'm living with Booth now." Summer explained.
"Oh Cool!" Christine shouted. "I always wanted a big sister, and though it's scientifically impossible to a have a full biological older sister,well a half sister is great!" Chris exclaimed.
"Can you be my big sister? I wanted one, but instead I got a big brother." Zooey questioned Summer.
"Yeah, ok." Summer said.
Brennan and Angela exchanged a smile as they walked out to the car.
On the way home the three kids talked to Summer about everything from favorite colors to favorite authors. When they got to Angela's the kids kissed thier mothers and went with Hodgins to the apartment where Zack was living.
"Now we party!" Angela said. And they did just that.
