Spencer Reid and his wife Hannah had twins. Hannah was ten years older than Reid. When they married, Reid was 24, she was 34. This was right before he went into the BAU. She got pregnant very quickly, giving birth at age 35 to twins. Reid's drug problem had almost broken up the marriage. When he came home and started screaming at Hannah and the twins, Hannah split with the children. She called Hotchner and soon Reid was on his way to a drug treatment and mental health facility. They had separated for 18 months while Reid got his life back together. Once he had been drug-free for 2 years, they decided to try to have another child. Nothing happened.

Reid began to wonder if his drug abuse had contributed to the infertility. The doctor found no evidence of this. Tobias have given Reid god only knows what other medications. The several days he was held captive by Tobias, Reid was forced to take handfuls of pills. Several times a day. Not being a pill popper, it was amazing that Reid wasn't dead after all this.

Reid seemed to be having a hard time dealing with the fact that he might have secondary infertility. Hannah wasn't so worried about it. She was fine with the two children.

Hannah had been watching the Show I Didn't Know that I was Pregnant. She found it hard to believe that this could happen and questioned whether this was real. . She'd had 2 kids and certainly knew she was pregnant.

They didn't discuss the issue again. Life went on. Hannah was at school volunteering when she suddenly had some very sharp pains in her stomach. She told the teacher that she needed to get some fresh air and stepped out. The pains got worse. Then there was blood everywhere. She ran to the nurses office. 911 was called.

Prior to the ambulance getting there, Hannah Reid gave birth to a baby son in the nurses' office. She had no idea she was pregnant. She looked the same, fit into the same clothing. Had normal periods every month and they were like clock work.

As a joke several months back, Hannah, Emily, Penelope and Agent Seaver went into a museum where there was a fertility goddess statue and had touched the statue. It was said that any female of childbearing years who touched the statue gave birth within 9 to 10 months of touching it. Hannah was the last one in the circle to give birth. The others had given birth a couple of days earlier.
