Steffy's pregnancy opens the door for chaos on 'The Bold and the Beautiful.'

Friday on The Bold and the Beautiful, Steffy dropped a bombshell on Liam by telling him she is pregnant. What she did not say, and possibly may address on Monday is that he is not the only candidate for the baby's father. Just days after sleeping with Liam, Steffy went to bed with Finn. She has been adamant that Liam keep their secret but now it may have to come to light. Dr. Finn could turn out to be the baby daddy and problem solved but that would make things too easy. Steffy is going to have to tell her beau at some point but in the meantime what will she do?

Since she wants to keep her night with Liam a secret, she did not have to tell him about her pregnancy. Steffy could have passed the baby off as Finn's and nobody would have given it a second thought. The fact that she called Liam immediately lets viewers know that he is really the man in her heart. She knows that if the baby belongs to Hope's husband he will never go along with pretending the child is not his. It could even be possible that Steffy and Finn used protection and she cannot pass the child off as his. This situation is turning into one big mess.

Brooke has opened her home for Thomas to recuperate from his brain surgery and she is trying to get along with her stepson to please Ridge. When the truth about Liam, Steffy, and the baby is revealed this may cause problems in the Bridge marriage. Ridge and Brooke each tend to side with their own children but they both will be in agreement that Liam's behavior was bad. Ridge knows Steffy still loves Kelly's father so he will want Steam back together for the sake of his grandchildren. Brooke, however, might push Hope to forgive Liam and insist his loyalty should be to his wife and Beth.

One way or another, this situation will put a strain on the Bridge marriage and with Thomas in the home things might be even tenser. Spoilers from Soap Dirt have suggested that Thomas will be the one to expose his sister's secret of sleeping with Hope's husband. It's not clear how he finds out, considering he is staying with Ridge and Brooke. It would be reckless of Liam and Steffy to be talking about the situation in front of him. Perhaps Steffy will be visiting her brother and talk on the phone while she thinks he is sleeping. The adultery and the resulting child should be enough for Hope to say goodbye to her husband and mean it.

If the baby does belong to Liam, Finn will be devastated, at Steffy's betrayal as well as the evidence of it. Most B&B viewers believe the doctor will simply be out of the picture unless the baby turns out to be his. Hope's life will be turned upside down and she might just seek solace in Thomas, which would cause her mother to become defensive. Brooke is willing to allow Thomas to heal while in her home but she does not want him trying to console her daughter. Disagreements between Ridge and Brooke. Hope's heartbreak and Steffy and Liam being exposed will bring about a lot of sorrow.

When you add Thomas and Finn to the mix the problem mounts. Thomas really is trying to live a better life and not resort to is previous methods. His love for Hope and anger at Liam might cause him to seek more than friendship from her. At first, he may be just a shoulder to lean on but it could turn into something more. Finn is new to all of this drama but was warned by Thomas that Liam always circles back to his sister. The bottom line of all of this is finding out who is the father of Steffy's baby. This will be the gamechanger that determines how most of this will play out.
