General Hospital Monday, March 23 Update: Cullum Attacks Marco, Nathan Saves Britt, Carly Snaps at Valentin

General Hospital (GH) spoilers update for Monday, March 23, indicate that Ross Cullum (Andrew Hawkes) will do what he feels needs to be done.

Nathan West (Ryan Paevey) will also stand in Jack Brennan’s (Chris McKenna) way while Carly Spencer (Laura Wright) gets irritated with Valentin Cassadine (James Patrick Stuart).

In the room above Bobbie’s, Brennan will stress the importance of speaking with Britt Westbourne (Kelly Thiebaud) immediately.

Nathan won’t trust Brennan and will do his best to block him from tracking Britt down.

Of course, Nathan would like to find Britt himself since he just showed up at her place.

Britt is already down on Pier 55 with Lucas Jones (Van Hansis), who’ll get a grim warning about what Cullum is capable of when he’s betrayed.

That’ll leave Lucas with growing concerns about Marco Rios (Adrian Anchondo), so he may mention some of them when he confides in Carly later.

As for Rocco Falconeri (Finn Carr), he’s been watching Britt from afar on the pier and may feel the need to take action somehow since she’s clearly in distress.

Britt has more danger ahead of her, but Jason Morgan (Steve Burton) will be dealing with another issue now that Dante Falconeri (Dominic Zamprogna) has cornered him to carry out the WSB’s warrant.

“Don’t do it, man. Not in front of your kid,” Dante warns in Monday’s preview video.

When Jason tries to insist on going inside the gym for Danny Morgan’s (Asher Antonyzyn) basketball game, Dante will push him to just come to the station willingly.

Otherwise, Dante might have to arrest Jason in front of Danny.

Back with Carly, she’ll snap at Valentin for not warning her about his intentions, but he’ll work to charm her again.

Perhaps Valentin will set the table for a romantic dinner and leave Lucas suspicious when he seeks Carly out.

Carly may be forced to cover and blast Valentin after the close call, but he’ll insist this was supposed to be a nice surprise.

Regardless, Carly and Valentin will ultimately share a meal together, so that could lead to more temptation.

Over with Laura Collins (Genie Francis), she’ll face more of Jenz Sidwell’s (Carlo Rota) demands.

Sidwell will have the nerve to act like Laura should be grateful, so she’ll grow to loathe him even more.

At GH, Brook Lynn Quartermaine (Amanda Setton) will tell Tracy Quartermaine (Jane Elliot) about her plans to be a foster parent to Baby Phoebe along with Harrison Chase (Josh Swickard).

Tracy will worry Brook Lynn is getting too attached and will suspect she might be using this baby as a way to deal with other issues.

Brook Lynn will rush to her own defense and make it clear that she intends to step up for Baby Phoebe no matter what.

Finally, Cullum seems poised to stab Marco for the medication theft and leave him bleeding in Alexis Davis’ (Nancy Lee Grahn) office.

General Hospital spoilers say Lucas will face some devastation soon, so stay tuned.
