After declaring her love to Nick, Katie reaffirmed, "It's the truth." Nick was stunned by the admission and Katie pointed out that she had felt something mutually brewing between them "for a long time." Before Nick could respond, Bridget swept in and interrupted their conversation. Nick left the room so Bridget could give her patient a check up. Katie started tearing up and thanked her niece for saving her life. Nick returned with Jack in his arms and Katie was thrilled to hold him. After Bridget took Jack out of the room, Katie acknowledged her love for Bridget. "If I ever hurt her, I would never forgive myself," Katie stated. "I will not let that beautiful, brilliant woman feel like a fool." Katie vowed never to come between Nick and Bridget. He kissed her hand and reluctantly left.

Marcus was touched when Brooke called his appearance in their lives "a miracle." However, Brooke urged Donna to come clean just as Eric walked in. "Is there something I should know?" he asked but Donna covered by praising Marcus's work performance. Eric then asked the young man's opinion on his sketches and while the guys chatted, Brooke pushed her sister to be be honest with Eric. After he left, Donna was overjoyed over how Marcus and her husband got along. "I can't wait to tell him you're my son," she squealed, then promised, "It won't be long."

Ridge was determined to find a connection between Marcus and Donna but Thorne reported that everything Marcus put on his application checked out. Felicia was still suspicious and told Thorne and Steffy to follow her. The troop came back with Marcus's backpack that they got from his locker. Felicia was disappointed when nothing incriminating could be found. After she, Ridge and Thorne left the room, Steffy discovered another pocket in the backpack. She then found Marcus's birth certificate. "Marcus isn't Donna's spy, he's Donna's son," she realized. When she turned around Marcus was standing in the doorway.
