As the team stood looking at the pictures and diagrams that Emma had arranged on the evidence boards she explained. "I think I got this right, but you will probably want to make your own changes. Also, I had the old files from the first two murders pulled. They are in those boxes over there." She pointed to a library table sitting against the wall.

"It is just right!" JJ assured her with a smile. "You took notes! Do you want to go over this with us?"

"Of course!" Emma told her as she pointed at a picture. "The first victim, Missy Logan, – "

As Emma began reviewing information she had assembled, Hotch took a firm hold of Rossi's arm and propelled him out into the hallway.

"You knew she was here, didn't you?" he began, sotto voce so they couldn't be overheard.

"Yes. I got a call asking for a reference when she applied for the job," Rossi calmly replied. "And, she sent me a Thank You note when she got the job. Since then she has sent me a couple of updates."

"You do know what this is going to do to Reid, don't you?" Hotch demanded.

"It's a risk we have to take," Rossi argued. "He's been in a total funk ever since she left. He's not eating, he's not sleeping, and he is slowly sliding into depression. When was the last time you heard him spout off with a series of facts and figures? And, Matt Cruz was commenting just the other day on how much weight he has lost. This should resolve the problem one way or the other."

"I hope you know what you're doing!" Hotch warned as he shook his head and then led the way back into the conference room.
