Jaws 2

Lori Peters is the younger cousin of Brooke and Jackie Peters.
When Brooke invites Jackie to stay with her in Amity, she asks if Lori could stay with them at Brooke's house.
Lori is an island native. She knows everyone in town where they live and pretty much every place on the island.
Mike Brody is a boy a year older than her and a senior in high school who was also born on the island, he loved to sail like Lori but Lori not only has been sailing her entire life but she's also the state champion swimmer for New England which she hardly ever shared.
When Brooke and Jackie not only convince Lori to come sailing with them but to go on a date with the mayors son Larry Jr otherwise known as Lar or Larry.
Though Lori has liked Mike for some time he seemed more interested in Jackie.
Sean on the other hand noticed things they both missed. He decided he would bring the two together.
