This is a a challenge fic, so bare with me. Anyone can add to this story, but it has to be somewhat liner. So you don't write the BBQ before the resurrection.
It is a crossover with Stargate SG-1.
Buffy is Jack's biological daughter-a Joyce/Jack love child. Jack doesn't discover her existence until she dies, leaving the good Colonel to mourn a second child. Months later, when the Scoobies bring Buffy back, she isn't alone. O'Neill's son, Charlie, is resurrected as well.
Disclaimer: I don't own Buffy, I don't own Stargate, and the suumary above shows that I don't even own the idea for this story. Oh well.
So lets get going Campers!
Chapter One, A Father's Grief.
Jonathan "Jack" O'Neill was a father once. He had married Sara O'Neill and had a son, Charlie O'Neill. There was an accident and his son had shot himself with his gun. No parent should ever have to bury their child, but how much worse would it be to be the cause of your child's death. It wasn't until a brilliant linguist solved the problem of the Stargate, and his was called to serve his country that he started to recover.
In time he saw and found out many strange things. He had a teenage clone made of him. But the worse thing he ever found out was about a girl named Buffy Summers. He had been off-world, or at the base on and off for the last two months, so when the letter reached him, Joyce Summers had long been dead and their child had followed her.
He had never met Buffy, never known the woman he had known before Sara had his child. But Buffy Summers had been his daughter, was dead and he now felt again a fathers grief.
Next part, In heaven, then back to 'hell'.
