The low sound of the vibration rumbled throughout the FBI building. It was a pretty stiff shock, causing furniture to move up, down, and sideways in response to the heavy rolling wave. It wasn't as strong as the last earthquake in the area at magnitude 5.7, but the USGS said it was shallow and there could be significant damage.

Per safety protocols, all agents who were assigned to check in with Booth had done so, and people were starting to move back to their designated areas, looking for damage and clearing the mess. Things were working as they were supposed to, with one notable exception. Booth still hadn't heard from his wife.

He knew the Jeffersonian had its own protocols and she'd be working, but she should've sent him an "I'm okay" text by now. He finally gave in to his worry and called her, but he only got her voicemail. "She must be busy", he thought, trying to be calm without much success. Finally his phone rang and the screen said "Bones".

"Bones, are you alright? Why didn't you call sooner?"

"Booth, this is Cam. We're hoping Dr. Brennan is with you..."

"No...she hasn't checked in?"

"Not yet. There's been some damage to the building and security is in the process of searching it in sections."

"Why are you on Bones' phone?"

"She left it on her desk…"

"Cam...that place is huge. She could be trapped anywhere and if she's without her phone...God. I'll be over as soon as I can."

"Just a minute"... Cam was talking to someone…."Wendell says she was going to Limbo, so I've asked security to check on her, but the stairwell is blocked with debris. It's going to take a while to get through."

"I'm on my way."
