General Hospital Monday, September 22 Update: Secret Nathan Investigation – Tracy’s Door Slam – Lulu & Britt’s Truce

General Hospital (GH) spoilers update for Monday, September 22, reveals that there’ll be a top-secret Nathan West (Ryan Paevey) investigation while Tracy Quartermaine (Jane Elliot) delivers a door slam. Lulu Spencer (Alexa Havins Bruening) will also push for a truce with Britt Westbourne (Kelly Thiebaud), so here’s what viewers can expect.

As the news about Monica Quartermaine’s (Leslie Charleson) demise trickles out to the rest of Port Charles, Sonny Corinthos (Maurice Benard) and Carly Spencer (Laura Wright) will have a somber conversation.

There’ll be some mutual concern for Michael Corinthos (Rory Gibson) and Jason Morgan (Steve Burton) since they’re definitely hurting right now.

As Sonny and Carly reflect on other losses of the past, they’ll know it never gets any easier.

Over with Lucy Coe (Lynn Herring), it doesn’t look like she’ll be in the loop on Monica’s death yet when she shows up at the Quartermaine mansion.

Tracy will be in no mood to hear whatever pitch Lucy intends to make, so she’ll slam the door in Lucy’s face!

Next, Brook Lynn Quartermaine (Amanda Setton) will hint about changing the rulebook – perhaps so that Cody Bell (Josh Kelly) can keep a new pup in the Q stables once he returns Outback.

However, Cody will sense that there’s more on Brook Lynn’s mind.

Brook Lynn will open up to Cody about Monica’s passing and might reflect on her uncertain relationship with Giovanni “Gio” Palmieri (Giovanni Mazza), too.

As for Molly Lansing-Davis (Kristen Vaganos), she’ll accept that she might be falling hard for Cody.

Molly will make Alexis Davis (Nancy Lee Grahn) her confidant and seek some romantic advice, so her mom will offer her perspective.

At GH, Anna Devane (Finola Hughes) will reel now that a man who looks identical to Nathan has shown up unconscious at the hospital.

This will launch a major investigation, but Anna will want to keep everything under wraps until they figure out more information.

Nathan was involved in a mysterious truck accident, so Anna and Dante Falconeri (Dominic Zamprogna) will compare notes with Harrison Chase (Josh Swickard) as they try to nail down some answers.

Lucas Jones (Van Hansis) and Elizabeth Baldwin (Rebecca Herbst) may promise they’ll stay tight-lipped about what they’ve seen, but they’ll definitely have questions about whether Nathan has truly returned from the grave.

As for Lulu, she’ll seek Britt out and hope they can establish some peace between them.

It’ll be what’s best for Rocco Falconeri (Finn Carr) as far as Lulu’s concerned, so Britt may agree to the truce she’s proposing.

Of course, Britt’s world will get turned upside down later. It turns out Britt will be quite thrown over this whole situation with hospitalized Nathan.

Anna may deliver updates and ask Britt some questions since she’ll suspect Cesar Faison (Anders Hove) is connected to all this.

Does Britt already know Nathan is alive – and if so, has Nathan been the one delivering orders to her at the Five Poppies Resort?

Regardless, General Hospital spoilers say Britt will be overwhelmed by all the Nathan drama that’s about to erupt, so don’t miss all the action.
