Kitty Smithers: Her Story
Both her parents were hunters but her father was the one who brought it to the family when he married Kana. He was home as much as he could be but was almost always out on hunts with various hunter friends such as Bobby Singer and John Winchester, who would sometimes leave his boys in the care of Kana. When Kitty was thirteen, Richard was killed by a Wraith and Kana, unable to accept her husband's death, left her child in the care of Bobby and went on a hunt of her own to find a way to bring him back to life without the use of the Crossroads Demon.
After a year and no word from Kana, the woman was declared dead and Bobby officially adopted Kitty. At the age of twenty, Kitty 'ran away' from her home, leaving in the middle of the night with no word and taking many weapons and other items she needed to start her own hunting for her 'dead' mother. Bobby believed the worst when he could not find her the next day but a phone call from the female calmed him. He was never happy the young girl became a hunter but he knew there was nothing he could do to stop it. Sam had not been happy with her choice but grew to forgive her actions. Dean, however, had gotten into a heavy argument with her over the phone and when she chose to hang up, it heavily damaged their friendship and he had not forgiven her since.
In 2004, Kitty was doing a regular hunt for a shifter in a small town when things turned to her having to save a twelve year old shifter named Remy. When Remy was able to gain an understanding of what she really was, she and her mother agreed that Remy should tag along with Kitty and learn the trick of the trade in hunting. Kitty, of course, accepted the girl with open arms.
