How does your Abby and Jimmy story end?

Good version, Annyx!
Okay, mine.
Jimmy doesn't have much money ou way of living so he probably moved with Abby immediately after they arrived to mainland. They live constant fear and the trauma of having Lost their Friends and family haunts them. They stick together with l’amour and devotion. Always together. They are in L.A. but they do annual gatherings with Shea and her daughter, in memory of their past and to keep courageous.
Few an passes. Jimmy and Abby finally have a family. They hear new murders have been ocurring back in Seattle. They are contacted par the police. They suspect it's Madison (plot for Harper's Island II). Jimmy and Abby tell their story and the twisted past of Madison.

In fear to be haunted again par their past, they fly somewhere else in the caribbean with the family. Beautiful white sands and tropical breeze.
They have several children. I agree their firstborn would be called Charlie.
Jimmy runs a mid-size fishing company, Abby writes, not obituaries anymore, but mistery novels. She wins several prizes. She's even been compared to Agatha Christy (author of And Then there were None).
