Carry on my wayward son

My little brother Jack and I grew up with the Winchester brothers and their father John who we call dad, after our mom was killed by the yellow eyed demon when Jack was six months old. We lived next door to the Winchesters, John and Marry were best friends with my mom so they were very close dad tells stories of all of us going to their house and having dinner and sleep overs so that my mom could have a little help with me and Jack but I don't really remember much. That's what happened that night when my mom and Marry were killed we were staying the night at their house and John heard Marry screaming and by the time he got up to the nursery they were both on the ceiling covered in fire, John told me to get Jack and for Dean to get Sam and we ran out of the house while John tried to help our moms but had no luck. From that day on dad trained all four of us, we were trained like soldiers. Dad would leave for days at a time and leave us kids at motels or Uncle Bobby's house while he went out looking for the demon but where ever we stayed Dad always told Dean and I to look out for Sammy and Jack. One time dad left us at Bobby's but never returned its been 20 years since we have seen him, now we are grown, we found the thing that killed our mothers and destroyed it, so now we save people and hunt things, the family business.
