Being the friend that she was Ange was worried when Bones didn't come into work that day. When talking to Hodgins and Zack about this they reminded her about the last time she wasn't her usual workaholic-self and she calmed down a bit.
Booth had just gotten his assignment from Cullen and he knew that Bones wouldn't be able to resist it. The remains were found near an old castle in Kentucky who looked to be a soldier long past. He called her house phone and left her a message and then called her cell still no answer. By this time Booth was panicking. He ran as fast as he could to his FBI standard issue car, jumped in and sped off.
When Booth walked onto the platform he saw The Squint Squad squinting at what looked to be a make-shift rat maze.
"Well it's nice to see our tax dollars hard at work." Booth said as he crossed the platform looking for any sign of Bones.
"The tax dollars don't go to solving murders on the streets. It goes to building spaceships and robots to bring the Earth its eminent doom." Hodgins stated.
Zack was about to argue what would have been a really compelling speech but Booth kindly interrupted.
"Has anyone seen Bones?" Ange climbed up to the platform with a file in her hand.
"No we figured she must have had company last night."
"Bones and I had dinner last night. It was around ten when we left. I really doubt anyone went over to her house last night."
"Well maybe Dr. Bennan wasn't feeling well." Zack proposed as if they were solving a murder case.
"I'm going to check on her. Angela do you have an extra set of key to her apartment. In case something is wrong. I don't think she'll appreciate me breaking down the door."
Angela handed over the keys and Booth left without another word.
