What a coincidence. Just as Bold & Beautiful leading lady Jacqueline MacInnes Wood is due to go on maternity leave — she and husband Elan Ruspoli are expecting their fifth child — Steffy’s wicked stepdaughter is hatching a scheme to, as she put it, “eliminate that threat” to her relationship with newfound daddy Finn.

Now, do any of us really think for a second that the soap would let the double murderess make it a threefer by rubbing out Steffy? Certainly not. She will remain front and center until the day that Wood wants to exit stage left a la Susan Flannery, for whose indomitable character the younger woman is named.

But Steffy will need to vanish from the canvas for a hot minute, and you can bet that Luna’s inability to grasp the way her stepmother refuses to forgive a gold-digging killer who couldn’t so much as define remorse, much less feel it, will play a “part” in her “departure.” How?

Option No. 1

Luna kidnaps Steffy. And why not? She’s done it before, drugging Steffy and leaving her locked in a cage in a building that was scheduled for demolition. This possibility gives Sheila a chance to discover what her granddaughter has done and actually behave in a sane, rational manner for a change. (She’s even advising Luna to steer clear of Steffy.) Sheila could take over her daughter-in-law’s care, whereas Luna was going to leave her to starve. So by the time the prisoner escaped — or was set free by Sheila — Steffy would begrudgingly feel indebted to her monster-in-law. Luna might be sent straight back to the slammer, but Granny might end up in those Forrester-Finnegan family photos after all!

Option No. 2

Luna kills Steffy. That is, she “kills” Steffy. Luna thinks that she’s removed the one obstacle to a relationship with Finn, maybe by running her stepmother off the road (like Maw May did Li). Luna delights in “being there” for Finn in his hour of need and even suggesting that Sheila should rejoice: This is her big chance to bond with him, too! Little do either of them know that an amnesiac Steffy has washed up on the beach and embarked on a friendship with a sexy surfer (maybe played by Days of Our Lives’ Greg Vaughan, ex-Eric). By the time Steffy discovers her true identity, maybe she’s caught feelings for the new guy and returns home not only determined to get Luna sent up the river but forget the handsome stranger who accidentally touched her heart.

Option No. 3

Luna’s determination to get all up-close and personal with Finn could drive Steffy to say, “See ya!” She’s done it before, after all. When the going gets too rough, she gets going, if only to regroup and come back stronger than ever. (Right, Sheila?) But that would be the least dramatic of the options. Which one do you think the show will go with?
