"The Young and the Restless" spoilers promise that Victor Newman (Eric Braeden) and Nikki Newman (Melody Thomas Scott) are about to hit another turning point in their marriage. What comes next for The Mustache and his long-time love is still up in the air, but it seems that they might close down their open marriage. If so, there are two schemers in Genoa City that might be out of luck!

Arturo and Helen: Siblings and schemers?

"Y&R" spoiler info has Arturo Rosales (Jason Canela) hitting GC in early February, and, coincidentally, Helen Wallace (Sitara Hewitt) came around mid-February.

Both were able to rapidly attach themselves to big power players in town. Arturo used Nikolas Newman (Joshua Morrow) as a stepping stone to meet Nikki and bound right into her bed.

And we learned recently that Helen was not only glommed onto Jack Abbott (Peter Bergman) by working at Jabot, but also is the mistress of The Mustache! Helen and Arturo have enough of a resemblance to be siblings and both seem to be interacting with the same set of power players in Genoa City. If they are running a con, is it about profit or payback?

'Y&R' revenge plan

As of now, Arturo and Helen are both romancing half the powerful Newman pair, but "Young and the Restless" spoilers hint that that changes soon. Victor is close to figuring out that Arturo is bedding his wife and he doesn't like it -- even though he agreed to the open marriage.

Nikki also didn't like having Helen at the ranch and staring down the table at her husband's mistress.

With Victor's recent death scare, Victor And Nikki might be thinking about resuming a traditional marriage and loving each other again. If so, that leaves Arturo and Helen out in the cold. And if the pair is scheming together, it shuts down their plans. Another question to consider is whether Helen and Arturo are schemers or whether they came to town with revenge on their minds.

A Santori scheme?

Its been a minute since Luca Santori was in town, but he's a big schemer and furious that he wound up in prison thanks to the Abbotts and Newmans. Given how powerful and bitter the Santori family is, perhaps Helen and Arturo are part of that crew and came to Genoa City specifically to target Jabot, Newman Enterprises, and the Newmans personally!

Are Arturo, Luca, and Helen family? Is there something deeper afoot her than just booty calls and boy toys? While "Young and the Restless" spoilers haven't provided details yet or much of a backstory, there is lots of potential here.

Helen supposedly had a reputation as a top chemist, but that doesn't mean she's not a Santori or that the powerful family falsified her background.

What do you think? Are Helen and Arturo working together? Are they schemers or just unlucky in love and about to get dumped by their older Newman lovers? "Y&R" spoilers tease that Arturo is also working an angle with Abby Newman (Melissa Ordway) which is another sign he might be targeting the Newmans for something more than romance.
