General Hospital Spoilers Thursday, March 19: Sidwell Vows Sonny’s Murder, Jason’s Armed & Ready, Britt Busted Leaving

General Hospital (GH) spoilers for Thursday, March 19, reveal that Jenz Sidwell (Carlo Rota) will make a dangerous promise to Marco Rios (Adrian Anchondo) while Jason Morgan (Steve Burton) prepares for a risky mission.

Ava Jerome (Maura West) will also deliver some words of caution, so there’ll be a lot going on in Thursday’s GH episode.

For starters, Josslyn Jacks (Eden McCoy) will catch Britt Westbourne (Kelly Thiebaud) with her luggage and wonder if she’s going somewhere.

Britt may be forced to spin a bogus story while Jason is busy getting ready to eliminate Ross Cullum (Andrew Hawkes) elsewhere.

Jason will open up his weapon case and look pensive over what he’s about to do.

Although Jason wants Cullum wiped off the map, he’s taking a gamble by plotting to kill someone in the WSB.

Over with Carly Spencer (Laura Wright), she’ll tell Jack Brennan (Chris McKenna) that if you love someone, you have to risk being honest with them.

Carly will apparently give Brennan a nudge to come clean about Josslyn’s WSB status and how he recruited her daughter, but he may keep his mouth shut.

Of course, Carly is keeping secrets of her own since she’s been hiding fugitive Valentin Cassadine (James Patrick Stuart) since shortly after his escape.

At GH, Ava will have a warning to pass along. Lucas Jones (Van Hansis) will get some advice from Ava whether he asks for it or not!

“She has set a trap and you are walking right into it,” Ava insists in Thursday’s preview video.

Will Ava realize Lucas is tangled up in some kind of trouble with Britt?

Will this be about keeping Lucas out of Elizabeth Baldwin (Rebecca Herbst) and Ric Lansing’s (Rick Hearst) romance instead?

As for Tracy Quartermaine (Jane Elliot), she’ll sit down with Alexis Davis (Nancy Lee Grahn) and argue that it’s up to them to sort it out.

Tracy will presumably be talking about the Danny Morgan (Asher Antonyzyn) guardian situation and may object to Jason picking Alexis.

While Alexis and Tracy argue, Marco will speak with Sidwell and get reassurance that Sonny Corinthos (Maurice Benard) will be taken out.

Although Marco’s been acting like he’s moved beyond that vengeful rage, he may still want Sonny eliminated deep down.

However, Marco will make yet another risky move and could put himself in grave danger.

Cullum now realizes Marco lied to him about Pascal (Marc Forget) and the miscommunication regarding Britt’s medication, so more trouble is brewing.

Speaking of trouble, Nathan West (Ryan Paevey) and Lulu Spencer’s (Alexa Havins Bruening) date has already been a bit of a disaster due to James West’s (Gary James Fuller) third wheeling, but they’ve finally scored some time alone.

Unfortunately, Lulu and Nathan’s bedroom session will get derailed, so will someone show up at the door or could Nathan get called into work?

General hospital spoilers say some surprising news is ahead no matter what, so stay tuned.
