“She’s always taking her mom’s words to heart,” says Metz of Kate.

“But I think it hits home and it rings in a different way than it ever has before.

How does she set up her life in which she’s truly happy?

Because she’s been on a hunt for real happiness for quite some time.”

“It’s really where the wound gets opened.”
