The Bold and the Beautiful (B&B) spoilers reveal that Bill Spencer (Don Diamont) is already giving Luna Nozawa (Lisa Yamada) a warm welcome to his family. Bill brought up his sons and suggested they would enjoy having a sister, but things may not go according to plan.

Of course, Luna is a lovely young woman who gets along with almost everyone.

There’s no reason to think Luna will feud with any of her brothers right off the bat, but conflict could indeed develop over time – especially when it comes to Liam Spencer (Scott Clifton).

B&B fans know John “Finn” Finnegan (Tanner Novlan) is Luna’s adoptive cousin and happens to be someone she looks up to a great deal.

It’s clear that Luna has a sweet bond with Finn, so she may become protective of his marriage.

That’s especially true since Luna knows Steffy Forrester (Jacqueline MacInnes Wood) from working under her at Forrester Creations – not to mention she’s dating Steffy’s brother, RJ Forrester (Joshua Hoffman).

Steffy and Finn are currently dealing with some relationship issues – mostly because Sheila Sharpe (Kimberlin Brown) is back and pulling Finn toward her.

However, more problems could develop now that Finn has become a Hope Logan (Annika Noelle) defender.

It’s easy to imagine Liam taking advantage of the situation and using this opportunity to pull Steffy closer.

If Luna realizes Liam’s trying to make a play for Finn’s wife, that could give her a chance to feud with her new sibling!

Luna had a family bond with Finn long before Liam, so she may side with her cousin over her brother.

As far as Luna’s concerned, she may think Liam needs to back off and give Finn some space to fix things with his wife.

It’s possible Luna will witness a moment between Liam and Steffy that looks too close for comfort.

Then again, maybe Luna could overhear a secret if Steffy and Liam ever discuss those two kisses that they never told Finn about!

Whatever the case, Liam could renew his fight for a romantic reunion with Steffy at some point, so will Luna just stand by and let it happen?

Could Luna get updates on Liam’s mission and stand against him?

The Bold and the Beautiful spoilers say Luna might become invested in saving Finn and Steffy’s marriage, so stick with us for predictions on any bad news that might bring for her sibling bond with Liam.
