Linda Twist

Linda Twist is the eldest of the Twist children, newly settled with her family in a strange old lighthouse full of odd goings-on. Sensible and a little superior about it, she tends to be the one rolling her eyes at her younger brothers' antics — right before the weirdness proves impossible to ignore.

She's the show's anchor of normalcy, which is precisely what makes the supernatural chaos around her funnier and stranger. Ebonnie Masini plays her with a straight-faced exasperation that never curdles into meanness, so when Linda's composure finally cracks, it lands as pure delight rather than mockery.
