As Morgan drove, Hotch turned in the front seat to speak with Reid who was sitting behind him. "I generally try to stay out of everyone's private lives," he told the agent. "But, I have to ask. Could Christine be pregnant?"
"I don't know how," Reid mumbled, hanging his head. "It was only once and we used condoms."
"Condoms – Pleural," Morgan interjected. "Way to go, Man!"
After giving Morgan a poisonous look, Hotch continued. "Condoms do have about a 5% failure rate."
"Well, that couldn't be the case here!" Reid insisted. "One of the ones we used I got from Morgan, and he told me he only gets the best."
Morgan caught Reid's eye in the rear view mirror. "Reid, I never gave you a condom," he protested.
"Yes, you did!" Reid insisted. "It was the third time I went into the field with you when you were telling me what I should be sure to have in my go bag. You told me I should always be prepared for anything, took a condom out of your bag, and threw it to me."
"Reid, how long ago was that?" Morgan asked quietly.
"Eight years, nine months, and seventeen days," Reid replied promptly.
Morgan and Hotch exchanged a startled glance.
"Reid, you do realize those things have a shelf life, don't you?" Hotch asked gently.
"A shelf life?" Reid seemed puzzled by the concept.
"Like a carton of milk" Hotch clarified.
Reid thought for a moment. "That's why she ordered decaff," he realized.
"What?" Hotch asked.
"That last day, the day she disappeared," Reid told him. "We went for coffee that morning and she changed her order to decaff. Also, she said she wanted to talk to JJ."
"If she didn't already know for sure, she must have guessed she was pregnant," Morgan filled in.
"Yes, Christine could be pregnant," Reid declared. "And, yes, the baby is mine!"
"Let's concentrate on getting you to the emergency room so we can find her. Then, we can get everything sorted out," Hotch told Reid as Morgan spun the vehicle into the hospital parking lot.
