I can remember Rachel's dads are killed and she's sent to live with Judy and Quinn since Judy was best friends with one of her dads. Later they adopt a little boy by the name of Lucas, I think. Quinn and Rachel grow up and move in together taking Lucas with them.
I'm not sure if it's in the same story or a sequel, but Quinn gets to see Beth again and didn't tell Rachel and Puck shows up being an ass. Any help would be great!
