The complexities of Kate’s character, specifically this season, have pushed Metz to act with even more authenticity and raw emotion.

“I’m so grateful that I get to be an instrument to tell these really beautiful relatable stories that we don’t talk about and women are even afraid to bring up,” Metz exclusively told PEOPLE about portraying Kate’s struggles with IVF and polycystic ovary syndrome (PCOS). “It’s exciting, that’s what art is supposed to do.”

Fans were devastated to learn aboutKate’s miscarriagein season 2 and Metz revealed “there’s so much going on” with her character.

As for what’s to come in season 3, Metz reminded fans and viewers “there are a lot of complex issues and emotions that she’s handling” and has yet to address. At the end of the episode, Kevin was the one who arguably made the most hurtful jab — without even realizing it — when he told Randall (Sterling K. Brown) about Kate’s “only one who can carry on a piece of Dad” remark.

“I want people to understand that she’s never really felt her feelings deeply and that a lot of them are just bubbling to the surface. As humans we don’t always know how to handle them or express them. Sometimes anger is really just sadness masked,” Metz said.
