Eliza looked out the window and watched a sea of clouds drift by. Aaron had readily agreed to her joining them. She did know more about John Carrington than anyone. She drifted in and out of their conversation regarding victimology.

It wasn't until Aaron asked, "So what else do we know about Carrington?" She turned toward the group.

Eliza took a deep breath. This was what she'd been dreading. "We know how he tortures his victims," She spoke quietly.

Rossi reached out and patted her hand. A simple gesture but at that moment no one could have done anything for her with more compassion. Eliza blinked back the tears.

"What can you tell us?" Blake asked.

Eliza began to detail her torture, her voice robotic in the account of events.

"I'm sorry I have to ask, but some of the bodies made it impossible to know if he raped his victims," JJ asked.

Eliza shook her head. "No. Slicing our skin to shreds was definitely his sexual release."

The laptop Dr. Reid had opened on the table buzzed into life and Garcia's face filled the screen.

"Hello crime fighters, I've contacted the Mills Acre's PD and they're awaiting your arrival."

"And?" Rossi asked.

"And another woman has gone missing," she hesitated.

Eliza felt a knot of pain growing in her belly, "Who?" She asked.

"Elizabeth Crowing," Garcia announced.

All eyes turned toward her. Eliza shook her head. She didn't know her.

"Was she a runner, Garcia?" Derrick asked.

"You betcha, and in training for the Boston Marathon."

"Why runners?" Blake asked.

Eliza focused on her hands, clasped tightly in her lap, "I don't know about the people you've dealt with, but in my practice I've found that many of them want what they can't have. At some point that obsession becomes so overpowering they'll do whatever it takes to have it."

Rossi shook his head, "One man's logic is another man's crazy." He told her.

Eliza continued, "Part of the reason his victims are runners is simply because he can't."

"Can't what?" Rossi asked.

Eliza turned. From the moment they left Quantico, Rossi had been her shadow. He sat next to her now.

"John Carrington has a heart condition. He's had several surgeries and can't tolerate long hours of overexertion."

JJ looked at the crime scene photos on her tablet, "What he does to his victims doesn't trigger his condition?" She asked.

Eliza turned back to the view outside her window.

"Not when you take your time." Eliza whispered.
