Bold and the beautiful - alternative version.

Sheila's genes

Steffy: Sheila is your mom?

Finn: Yes...

Steffy: So you knew and you allowed me to love you!?

Finn: Steffy... I know since days... I never knew who my birth mother was before.

Steffy: And since when do you know Diana?

Diana: More or less as long as Finn.

Steffy: It's a dark joke... It can't be real. First Sheila's daughter is my aunt... Later Brittany becomes my cousin and now my fiance is Sheila's son? I mean... What else will I find out?! 

Diana: Steffy, I know that you are hurting, but we love you. We didn't want to tell you because we knew you'll suffer.

Steffy: I do suffer! How can I not?

Finn wants to hug Steffy.

Steffy: No! No! I need to be alone right now. 

Steffy runs away.

Finn wants to follow her, but Diana stops him.

Diana: Wait...Let her be. She's in shock.

Finn: She might hurt herself. I am not leaving her alone.

Finn follows Steffy. 

Diana takes out her mobile and texts Sheila.

Next scene: Sheila and Li still talk.

Sheila: I love my son and...

Text arrives. Sheila reads it.

Sheila: Oh...

Li: What?

Sheila: Steffy found out... And she's mad.

Li smiles, but Sheila looks scared.

Next scene: Steffy storms into the cliff house and shortly after Finn follows.

Steffy holds her stomach and cries.

Steffy: I feel sick.

Finn: This is what I wanted to protect you from, but I couldn't hide it from you anymore because you saw me and Diana hug and I didn't want you to think we have an affair... 

Steffy: So otherwise you would just keep it as a secret, right?

Finn: Steffy... What am I supposed to say?! I love you... I will always protect what we have.

Steffy: You should come to me immediately and tell me the whole truth.

Finn: So you would hurt?

Steffy: So I would know the truth.

Finn: So you could... End our relationship? Is it what you are trying to tell me?

Next scene: Diana and Sheila talk in Sheila's room.

Diana: Thanks for seeing me.

Sheila: Anytime sweetheart.

Diana: Steffy was so hurt.

Sheila: She still hates my guts.

Diana: Apparently.

Sheila: But you don't, right? Finn doesn't... Right?

Diana: Of course we don't hate you, but you being our mother does complicate things. I am scared that Steffy will leave Finn... It will crush him. You have no idea how much he loves this girl.

Sheila: I know how strong love can be.

Diana: I'm so heartbroken for them.

Next scene: Steffy and Finn still talk.
