Marlena has barged in on John and Kristen's wedding, and says it's over. Suddenly Abe comes in and announces that Stefano has gotten away, and Marlena is relieved that at least he's not in the house. John says he's so glad Marlena and Kristen are okay, comments how they must have bonded down in that room, and then says now Marlena can be Kristen's matron of honor. Marlena shouts out "NO! I can't be your matron of honor and I can't let this wedding take place." Kristen tells the father they need to sort some things out, and John asks Marlena what is wrong. Kristen tries to say it's the gas and she needs to be taken to the hospital. Marlena says it's truth time, and John needs to know just how much of a DiMera Kristen is. John says she can't be serious, and Kristen says it's just because of being locked in that room. Kristen asks Marlena why she is saying these horrible things, but Marlena says Kristen has been helping Stefano the entire time. Marlena says she will no longer keep silent, and tells John that she doesn't want to see him hurt, but he needs to know the truth about Kristen. John says he can't believe what he's hearing, but he knows she'd never lie to him. John says he thinks he understands what is going on, and then asks the father to continue with the ceremony. Everyone is shocked, and Marlena asks him how he can do this. John says it's just a big misunderstanding and that Kristen is a victim as well. John thinks everything evil was done by Susan, and Kristen says Susan had Vivian and Ivan's help. Marlena says that Vivian and Ivan were Kristen's side kicks, and Susan was her mixed up patient. John finally gets a clue, and Marlena tells him that Kristen is has been lying over and over. Kristen keeps yelling about being married, and John says what difference does it make, they are already married. Marlena says they are not, John married Susan in the hospital, and Susan was the one who gave birth to John Jr. Austin eventually shows up and sees Marlena as she is telling him that Kristen was never pregnant, and John Jr. is Susan's baby. Carrie tells Marlena this is her chance to be happy and to tell John everything. Marlena tells John that Kristen lost the baby in Paris, and faked her pregnancy. John looks at Kristen, who tries to make him believe her by saying he was there when the ultra sound was done, and Marlena can't explain that. Marlena says Susan must have been the one passing as Kristen with Kristen and Stefano's help. Laura says John has to believe her, and Kristen says the only ally is a mental patient. Kristen says nobody can back up her story, but Marlena says Susan can.
Out back Vivian and Ivan are angry with Susan, and they tell her that Marlena is inside telling John everything. Vivian realizes there could be a way out of this for all of them, but Susan has to do what Vivan tells her to. Abe comes to get Susan, and Vivian tells Susan to remember what they discussed. Susan is brought in, and John says he has some questions for her. John asks if Kristen gave birth to John Jr, and if he married Kristen in the hospital, or if it was her. Susan says it was Kristen, and Marlena asks her who she's lying. Laura won't let this happen, and she storms out of the room as Kristen glares at Marlena. Celeste tells Lexie that Susan is lying, and Lexie says she is probably write about this as well. Marlena tells Susan it is very important that she tell everyone the truth, but Kristen gets angry and tells her to stop badgering Susan. Kristen asks John if Marlena could be re-possessed. Marlena asks Susan why she is acting like this, and asks if someone is threatening her. Suddenly Laura shows up with the baby and whispers something to Marlena. Marlena takes the baby and says the only thing to do is to give the baby to his mother forever, since Susan said Kristen is his mother she goes to give John Jr. to Kristen. Kristen is about to take the baby and Susan screams that the baby is hers, and everything Doctor Marlena Evans said was true.
Austin calls Sami and tells her that Marlena is fine, and she's at the DiMera Mansion house. Sami wants to talk to her mom, but Austin says things are very tense and that Carrie will probably explain everything to her later. Sami is relieved, but she is afraid her mom will know she's faking her amnesia. Sami then begins going through the mail and gets a letter about Will's blood test from the hospital, and she notices that Will's blood type is different than hers, but just thinks it must be Austin's type.
Stefano returns to one of his hideouts and is pissed that Laura escaped the hospital and showed up at the wedding and ruined everything. Stefano tells Bart he's not about to give up, and asks Bart to tap into the security monitors at Kristen's place so he can see what's going on. Bart eventually taps into the house, and Stefano watches what is going on.
At the wedding Susan says the baby is hers but Kristen says that she's lying and that Stefano probably tried to take the baby so John wouldn't raise his grandson. Kristen tells John that Stefano wanted to kidnap Marlena and John Jr., and the only reason he let the wedding go on because he knew John wasn't marrying is daughter. Susan yells that Kristen is lying at she swears on a stack of Bibles that Elvis is her baby. Celeste butts in and says that she feels Susan is the baby's father, and John says that she has been right before. Kristen says that the only reason Celeste is backing up is because she is still working for Stefano. Laura interrupts and says that at the funeral she saw Kristen adjusting a pregnancy pad at Peter's funeral, and that she saw Stefano and Peter inside the church. She says that is why Stefano kidnapped her, and that is why he used a laser to erase her memory. Kristen says that Peter is dead, and Marlena says that it was Daniel Scott, she heard it from the secret room. Laura says that it was Daniel, and when she tried to expose her Kristen went and cremated Peter. Kristen says that Laura's nuts and will say anything to get Jack out of prison because she still loves him. Marlena says there are two people who could end Kristen's reign of terror, Vivian and Ivan. Viv and Ivan try and run, but Abe catches them and drags them inside. John gives them the chance to come clean because he's losing his patience. Stefano calls Vivian, and when he tries to warn her she says wrong number and hangs up. Vivian says she refuses to speak without and attorney, and Ivan swears that they had no idea Kristen was in the secret room, and Vivian says Stefano said they would kill them if they told about Marlena, and Kristen didn't know anything about him. Kristen says this is all a misunderstanding, and when she asks Jen to back her up Jen refuses and says she doesn't know what to believe anymore. Kristen says that when she learned Susan locked Marlena up she went to save her, and Susan locker her in there to. Susan cries "Kristen you are such a liar!" John says write now all he knows is that Kristen loves him, and that baby, and he has no choice but to believe Kristen. Kristen hugs John and cries how she knew he wouldn't believe the accusations. John says he would believe her if he only looked at the evidence, but he has to follow what his heart tells him. John says Marlena is the most honest person he's ever met, and he has to believe everything she tells. Marlena cries that the nightmare is over, and Stefano says the nightmare has only begun. Kristen says she loves him, and John says she doesn't know the meaning of love. John screams that she lost there baby and didn't have the decency to let him morn the baby. Kristen begins to bawl and says if she told him the truth that she'd lose him, and John says she just postponed the inevitable, she's lost him forever. Kristen gets on her hands and knees and starts begging forgiveness, and admits that everything Marlena said was true. Stefano yells where Kristen's DiMera backbone is, and he can't let him go to Marlena. Marlena tells John she's so sorry he had to be hurt this way, and Susan asks John if he's going to lock her up. John says she's just a victim as well, so he won't lock her up. Marlena tells Susan she'll make sure nobody takes her baby from her, and Susan says she's sorry she tricked him, she just wanted him to fall in love with her. Susan says she would have told him in time, and she says she's loved him since they were married in the hospital. Susan says she's a real good girl, not like that mean mean mean Kristen, and she wants him to know that he made her feel so beautiful when they made love. John is so shocked that he never knew the difference when they made whoopee. Susan kisses John, and Mickey takes her up to see the baby. John hugs Laura and tells her he's so sorry he ever doubted her. Laura says it's okay, and she is glad it's over. John tells Marlena they have a lot to discuss, but first he wants to go check to make sure Stefano is around. Carrie is thrilled that Marlena is safe, and now she and John can be together. Stefano says he'll never let her be with John, and tells the monitor one way or another, she will be his. Stefano says taking her with him now will have to be put on hold, but he does want to take Lexie with him when he leaves Salem. Celeste tells Lexie she and Abraham will protect her from the DiMera curse, but Stefano just laughs when he hears her.
Carrie notices Austin's handwriting on some flowers, and can't believe he didn't even say hello. Jen asks Kristen how she could have been so cruel to her mother, but Kristen says if it wasn't for her Stefano would have taken Laura with her. Jen asks Kristen if she has one shred of decency then tell her if Peter is alive. Kristen becomes furious and tells everyone to get out of her house now. Abe asks Celeste to take Lexie home and for them not to let anyone inside. Everyone wishes Marlena well as they leave. Carrie tells Marlena that today was proof that miracles happen and true love can win out. Abe tells John that they will catch Stefano this time, and he also tells John he knows what has to be done about Kristen. Abe leaves John alone in the garden, and John thanks God for helping him save Marlena from that evil man and his daughter. John goes back inside to see Marlena but Kristen asks him to talk with her alone so she can make her understand. John walks to Marlena, and a cop arrests Vivian, Ivan, and Kristen. John asks Marlena to forgive him, and she says of course she does. Kristen thinks this is all Marlena's fault, and takes a gun from the cops holster and points it straight at Marlena! Stefano begins to scream "No Not Marlena!" Back at the house John asks Kristen not to do this, but Kristen says "If I'm going to lose everything, then so will she!"
Upstairs Susan tells little Elvis she doesn't know what is going to happen to the now.
