In Good Witch‘s series finale on Sunday, Cassie, Abigail and Joy prepare to face the mysterious force putting their family legacy at risk.

It’s a long ways off from the marina, but he’s going to need a home more permanent than the boat if he’s going to become a foster father.

* Matt Lanter lookalike Donovan surprises Abigail with two tickets to Tuscany.

But after seeing Adam decide to uproot his life to move to Paris with Stephanie, Donovan and Abigail realize that they’ll never put their relationship first and break up.

The morning after, Abigail tells Cassie and Joy that she’s decided to go to Tuscany without Donovan — and it may be a permanent move.

* When Joy’s ex-girlfriend Charlotte arrives in Middleton, Zoey worries that she’s going to lose Joy.

In an effort to show Philip’s daughter just how much she means to her, Zoey asks Sam for an impromptu salsa dance lesson, and surprises Joy when they return home from Stephanie and Adam’s wedding.

But it’s not a marriage proposal — it’s a promise to change his ways… and that begins with a trip around the world.
