Port Charles is bracing for one of its more dramatic weeks yet.

Grief, mystery, and revelations collide as characters old and new are drawn back into the fray.

With Monica Quartermaine laid to rest, Nathan’s unexpected reappearance, and secrets threatening to unravel, it’s clear: this week will change many things forever.

Nathan West Back From the Shadows

One of the most stunning spoilers is the return—or at least the near-return—of Nathan West (Ryan Paevey). A man who looks like him is found unconscious in a hospital, and Anna Devane is hiding this man, insisting that his presence be kept secret. The question buzzing in Port Charles is whether this is really Nathan, or someone impersonating him. Either way, his “return” shocks Britt Westbourne, who already has a tangled history with him. What she knows, what she’s done, and how Nathan’s survival (if confirmed) reverberates through her secrets will be central to her arc this week.

Monica’s Death & The Quartermaine Farewell

Meanwhile, Port Charles is saying goodbye to one of its longest-standing pillars: Monica Quartermaine has died on-screen. Her death isn’t just symbolic—it sets off waves. Jason and Tracy are shown reflecting on her legacy, and the Quartermaine family’s fortune, influence, and internal power dynamics are now up in the air. New faces may emerge, and old wills, letters, or hidden documents could surface in unexpected ways.

Molly, Britt & Cody: Secrets and Shaken Trust

Molly Lansing-Davis finally opens up to her mother, Alexis, about her feelings for Cody Bell. Her internal turmoil has been building, and this confession suggests she’s beginning to carry more agency in her storyline—yet the weight of secrecy remains heavy. Cody himself is dealing with concerns about his dog Outback, tied to the Quartermaine estate, adding a personal angle to the family’s grief.

Britt Westbourne faces double shocks: Nathan’s possible survival complicates her world, especially given whatever she’s hiding, and to make matters more emotional, Lulu Spencer comes knocking—trying to make peace related to her son Rocco. Britt is being pulled in multiple emotional directions this week.

Sonny, Carly & the Corinthos Struggle

Sonny Corinthos and Carly Spencer are not just supporting characters in this season—they are central to how Port Charles processes grief. Both are receiving updates about Monica’s death, and both are shown dealing with the ripple effects among their family: especially concerns over Michael and Jason. Their responses will test how much power, vulnerability, and forgiveness exist in their relationship and leadership in the community.

Surprise Guest & A Mystery Face

Adding intrigue, a surprise guest is teased in promos. At the Quartermaine crypt, Tracy finds a stranger standing by one of the plaques, asking “Who are you?” That stranger is played by Erika Slezak. What does she want? How is she tied to Monica’s past, or the current secrets swirling in Port Charles? Her presence is likely to bring more questions than answers—especially for those connected to the Quartermaine legacy.

Why This Week Counts

This isn’t just a week of shocks—it’s a pivot. The return of Nathan, the emotional weight of Monica’s passing, and the way secrets are starting to slip out will shift relationships. Loyalties may break, new alliances may form, and identities will be tested. Questions like “Who do you trust?” and “What part of you is defined by your past?” will dominate.

By the end of Sept 26, Port Charles may not feel like the same town. Grief, secrets, and surprise may leave characters forever altered.
