A/N: the word for this one is lab and it takes place post season 12…
The Jeffersonian employee daycare closed just after lunch after they lost heat in their part of the building. Rather than loose Brennan and Angela for the rest of the day Cam made an exception to her 'no children in the lab' rule as long as four year old Hank and five month old Katherine stayed in their mother's offices. Hank was happily laying on Brennan's office floor coloring and drawing pictures for her to hang in her office.
"Mommy?"
"Yes, Hank?"
"Are those heads on the wall real?"
"The skulls are real, Hank." Brennan closed her file and pushed her chair back, standing up. Brennan went over to the shelves and picked up one of the skulls and walked over to where Hank was now sitting up. She knelt next to him. "This skull belonged to a man a little younger than daddy."
"Oh. Why do you have it?"
"Before daddy and I started working together I went to faraway places and I'd find skeletons and I'd identify them. Sometimes I wouldn't find the whole skeleton so I'd bring what I did find home in case I found the rest of the skeleton someday."
"Oh. What do bones look like?"
Brennan smiled a little and kissed Hank's forehead," I'll answer your question in a minute. Finish coloring your picture."
"Okay."
Brennan stood up and put the skull back on the shelf and left her office. She went in the bone room and pulled a set of remains from the storage system, after making sure it wasn't a child and they hadn't been shot she quickly laid the bones out in anatomic order on the light table. With that done Brennan went back to her office.
"Hank, do you want to see what bones really look like?"
"Yeah…"
"Come with me…"
"Okay." Hank put his crayons back in their box and walked to Brennan, taking her hand. Brennan walked Hank to the Bone Room and picked him up, sitting him on a stool. "Please do not touch anything unless I say you can."
"Okay."
"This is what the bones in your body look like without the muscles and skin covering them. The human adult body has 206 bones that make up the skeletal system. Children's skeletons have 300 bones that make up their skeletal system. As you grow the bones in your skull fuse together. The three small bones in your sternum fuse to form one bone." Brennan snapped on gloves and picked up the sternum and held it where Hank could see and pointed out where the bones fused together.
"Cool."
Brennan smiled, "Yes, bones are cool." Brennan spent the next 45 minutes giving Hank a simplistic bone lesson, he listened intently and asked a lot of questions. When Brennan finished, she helped Hank put on a pair of way too big gloves and hold a tibia. "Mommy, where did the bones come from?"
"You know that usually police find bones and if they don't know who they are or how they died they call me and daddy so we can figure it out, right?"
"Uh-huh."
"Sometimes instead of calling me and daddy, the police and other museums just send the bones to me. That's how I got these bones."
"Oh. Do all these boxes have bones in them?"
"Most of them. I work on the bones in these boxes when I don't have any bones to work on with daddy."
"Cool. Can I go watch movies in Aunt Angela's office now?"
"Yes." Brennan helped Hank take off his gloves and carried him to Angela's office. With Hank happily watching Disney movies and eating snacks in Angela's office Brennan retuned to the Bone Room and started working on the set of remains she'd showed Hank.
B&B
Later that night Booth was tucking Hank in, "did you have fun at the lab with mommy, today?"
"Yep. Bones are cool!"
Booth chuckled, "They are… Mommy is the coolest bone lady in the world!"
"Yep!" Booth kissed Hank's forehead and headed for the living room, he sat next to Brennan.
"Hank really enjoyed the afternoon in the lab with you. He says bones are cool!"
"They are cool. I enjoyed having him with me at the lab today. I wish I could have him and Christine with me more often."
"Talk to Cam, they're not babies anymore. They're well behaved and you know they'd stay with you."
"Hank, had lots of questions, not about what you and I do, his questions were about bones. I was a little surprised."
"Maybe he'll be a squint when he grows up..."
"Perhaps, but it doesn't matter if he's not. All that matters is he's happy."
"Yeah…"
