Liam-laughing-bill-grandpa-BB-CBSAt Spencer, Wyatt learns from Liam that Bill got a text and ran out. Wyatt’s frustrated; he was in the middle of something. Liam needles, “What’s her name?” Talk turns to Bill becoming a grandpa and the brothers share a laugh before reflecting on how well he and Steffy get along. Wyatt predicts the kid will bring the family closer together.

At Bill’s place, Steffy demands honesty and asks him if he had sex with her to get revenge on Liam. Bill protests…that night was about them and nothing else. They rehash the circumstances – they were there for each other. It was never about revenge. Steffy apologizes and leaves for Dr. Campbell’s office.

At the doctor’s office, Steffy panics as Dr. Campbell enters with a file. “I need to know who the father of my baby is. Are those the paternity results? I need to know!”
