Jess:

Jason’s influence was all over that as well. He made everything in that house a competition. If one of the girls did something good, like got a good grade, he would use it to put the other one down.

But what were Becca and Andie like together?

Jess:

I mean, they were teenage sisters, they fought like hell and then a few minutes later it was forgotten. Becca always looked up to Andie, though. They were really close in age, only fifteen months between them. Andie was in the year just above us at school. And when we turned sixteen Becca started, I guess, trying to copy Andie. I think because Andie always seemed so confident, so admired. Becca started trying to dress like her. She begged her dad to start teaching her to drive early so that as soon as she was seventeen she could take her test and get a car, like Andie had. She started wanting to go out like Andie too, to house parties.
