If it turns out to be true and Finn is Luna’s father on The Bold and the Beautiful, then we’re all in for a very bumpy ride as Finn is forced to come to grips with the evil side of his DNA while Steffy must decide if she can be with the man whose relatives tried to kill her.

Luna’s paternity drama will have shocking twists and turns on The Bold and the Beautiful. The results could disrupt someone’s marriage and have an unexpected pairing. Dr. Li Finnegan (Naomi Matsuda) wants to know if Jack (Ted King) is Luna’s (Lisa Yamada) father.

Here’s what we know: Poppy was sleeping with a lot of people back in the day. She was on drugs, so she’s probably not even sure how many men she was with. She was also staying with Li, Jack and Finn. We also know that Bill (Don Diamont), Jack and Tom Starr (Clint Howard) are not Luna’s father. So…was it the mailman? The UPS guy?

Fans decided that if Poppy slept with an extremely young Finn and Luna was the result, it would be utterly horrible.

The actor, who first appeared as Finn's father in 2021, talks his return when estranged wife Li summons him to determine if he fathered Luna.

If Luna is revealed to be Finn’s half sister on The Bold and the Beautiful, it has the potential to shatter Finn and Steffy’s relationship. Poor Finn (Tanner Novan) can’t catch a break. It’s bad enough that his birth mother is the notorious killer Sheila Carter (Kimberlin Brown).
