Belle Rayburn

Belle Rayburn is married to Kevin, one of the four Rayburn siblings anchoring this Florida Keys family drama. She works alongside him at the family business, trying to keep some steadiness in a marriage strained by his temper and the undertow of old family history. She's watchful, practical, and used to smoothing things over.

Katie Finneran plays Belle as the person standing just outside the Rayburn bloodline, close enough to see its damage clearly but without the family's instinct to excuse it. That outsider clarity gives her a quiet moral weight, and Finneran lets exhaustion and love sit on her face at the same time without resolving into either.
