John was hunting a werewolf in New Mexico, September 1989. He was following the trail into a wooded area, when he ran into a pregnant woman holding a gun.
"Listen lady, you need to get out of here." John whispered.
"Why's that? It's my kill, my werewolf; I've been tracking it since the last full moon." She whispered back.
"You're a hunter?" John asked.
"Anne Keever. My dad raised me hunting." She replied.
"John Winchester, my wife-" John was cut off by Anne giving a shriek. "Anne!"
Anne had collapsed, the werewolf lept over her, and John fired his gun, and the wolf fell onto Anne. John rushed over, shoving the werewolf off of Anne.
"Anne! Are you alright?" John asked.
"John- It got me," Anne said, breathing heavily.
John looked down, Anne was covered in blood and her top was ripped, right over her heart which seemed to be the source of the blood.
"John… My water broke. Save my baby." Anne was breathing heavily, "It got me, it got me good. I'm gonna die."
"You aren't going to die Anne, just calm down." John, pressed down on her heart, we're gonna get you to a doctor."
"John my baby girl Aiden, save her pl-" Anne trailed off.
"Anne!" John lifted his bloody hands and felt for Anne's pulse, which wasn't there. He pulled his knife out of its shaft and ripped Anne's stomach open, pulling out an infant. He smacked its back, and the baby began to cry. "Hey Aiden Anne, welcome to the world."
He wrapped Aiden, whose sobs had quieted; in his jacket. He looked down at Anne and noticed a necklace around her neck, a cross with an amethyst center; He undid it and placed it around Aiden's neck. He slung Anne's body over his shoulder and took Anne and Aiden to the Impala.
