Austin tried to convince Billie that she should tell Bo the truth but again she claimed she would never tell. Carrie took Romans suit to the police station so he could get dressed. While there, she saw a photo of Curtis and told Bo that Lucas had shown her a similar photo the night Curtis was killed, saying that Lucas seemed desperate to find Curtis.
Bo confronted Lucas but Lucas denied knowing Curtis, explaining that he had shown Carrie a photo of a teacher from the military academy who was visiting. Lucas told Bo he was not desperate to find this man. Bo was suspicious and noticed the burnt gloves in the fireplace.
Kate visited Viv at Pinehaven. Kate was pleased to see that she was catatonic. She asked Viv why she had come to Salem on New Years.

John and Marlena told Sami that they had decided never to tell Roman the truth which delighted Sami. Peter and Stefano discovered that John was the father of Belle. At the church, Peter told Marlena that Stefano knew about her affair with John and that he wanted to tell everyone before he died.
Midway through the baptism ceremony, Stefano arrived in the church, seen only by Marlena. She knew that Stefano would tell Roman of the affair so she tried to stop the ceremony so she could tell him, herself before Stefano could. Roman would not wait until after the ceremony so Marlena told him that she had broken their marriage vows by sleeping with another man. Roman was shocked as was the entire congregation.
Kate arrived back in Salem and was surprised to see Bo questioning Lucas about the Curtis Brown murder. Victor tried to assure Bo that Lucas had nothing to do with the murder. Kate asked Lucas why he had gone out that night. She was frightened for Lucas and he wanted to know why Kate seemed scared of what he may have seen. Victor assured Kate that he would not let anyone hurt her or Lucas and he would do all that he could to protect them.
At the church, everyone was shocked when Marlena told Roman that she had had an affair. Roman refused to believe it thinking that Marlena was under a lot of stress. Marlena, crying, told him she was speaking the truth. Sami was especially distraught and told her mother that she should have kept quiet like she had promised to do. Roman realised that keeping the secret had been the cause of Sam's emotional problems and blamed Marlena for letting Sami suffer. At this point John stood up for Marlena. Roman told him to stay out of it but John admitted he was the man Marlena slept with. Roman attacked John but Shawn and Caroline broke up the fight.
Everyone left the church except Roman, Marlena and John. Roman was angry and questioned John and Marlena about the affair.

Again she tried to explain that John and her never resolved their feelings for each other and neither of them had wanted to hurt Roman. She told him that she still loved him and wanted their marriage to work.
Kristen went to the hospital to tell Stefano of the news. He admitted to Kristen that he had gone to the church, not realising the baptism was on, and had overheard Marlena confess. John arrived and blamed the confession on Stefano. Kristen defended her father saying that his sleeping with Marlena was not her fathers fault. Later John assured Kristen that the affair had taken place before he had become involved with her and once he started seeing her, he had been with no other woman. Kristen was unsure of this but once again told John to leave her father alone.
Peter told Alice and Jennifer about Marlenas confession. They were both shocked. Alice warned Jennifer about getting involved with Peter, especially since he was raised by Stefano. Jennifer pointed out that Kristen and Tony were both good people but Alice claimed that Peter seemed to be like Stefano. Peter drove Jennifer home and Jennifer invited him in.
John went to the Brady pub and recieved a hostile reaction from Shawn, Caroline, Carrie and Sami. He begged them to try and forgive Marlena even if they could not forgive him. Roman arrived and attacked John. Shawn and Abe broke up the fight and insisted that John leave.
Marlena was consoled by Lexie and then Alice. Marlena told Alice that Peter had warned her that Stefano had known of the affair. Marlena admitted to Alice that she did not know what Peters motives were in telling her that Stefano knew. Marlena went to the pub to get Belle and was met by john outside. He suggested that she not go in as the Bradys were still very angry.
Carrie was quite upset by the news of the affair and told Austin that the news had made her reconsider the meaning of love. She told him she did not believe in love or that their relationship could work and broke up with him.
Abe and Lexie realised that their problems were quite trivial next to the problems that Roman and marlena were having. They decided to work on repairing their marriage and kissed.
Jennifer and Peter had coffee and cake at her house. Jen told Peter that Alice had warned her about getting involved with him. Peter told Jen that Alice had also warned him about getting involved with Jen so soon after being abandoned by Jack. Jen apologised for her grandmothers interfering but Peter did not mind. Later he put together a rocking horse for Abby that Jack had bought.

Carrie claimed that if a strong marriage like Marlena and Roman's hasn't succeeded, no relationship could ever succeed. Austin tries to convince her not to give up on their relationship, that they have been thrown a lot of things that they have gotten through. He brings her flowers, but Carrie says that she can't handle that pain right now and she asks him to leave.
Shawn and Caroline tried to comfort Roman. Shawn explained how he felt betrayed when he learnt of Caroline's affair and how Bo was not his son. This made Shawn ask Roman if it was possible Belle was not his daughter.
