Jessica leaves and Ben asks, "So how many times do I have to ask the same question and not get an answer?" Marshall asks, "What question is that?" Ben asks, "What is the real deal between you and Jessica?" Marshall tells Ben that Jessica is helping him find his daughter and she is going to Washington to be his advocate. Ben asks if Marshall asked Jessica to do this or did she volunteer. Marshall says that she volunteered.

She tells him that he is like a magic potion and she feels so good having him around. She asks him to stay around forever. He says that he will and the two share a kiss.
Alison meets Craig at the coffee house. She has an attitude about Craig "needing" her now. Craig tells her to lose the attitude, but she keeps the smug look on her face. Craig tells her that he does need her to help out with Aaron but they need to set some boundaries. He tells her that she had better not try to put anything over on him. She smiles and says that she must have a reputation and she loves it. Craig tells her that there are certain things that he doesn't want his daughter to remember and Alison knows what "incident" he is talking about. Then he makes a reference that Alison doesn't want Lucy to remember something either and he wonders what that could be. She says that she admits that she has a crush on her best friends boyfriend and she wants them to grow apart. Alison then has a flashback of when she told Lucy that she was the one who set the fire in the barn. Alison tells Craig that they need a plan to help Lucy get over Aaron. Alison tells Craig that she could work on Lucy and convince her that Aaron had done something really bad and she was running to him the day that she got hit by the trolley to have it out with him. Craig tells her that she could never pull that off. Alison says, "You want to bet?"

Emily stops him and then she tells him about the night that Carly had thought that Jack was finished with her and Jack had called off the wedding. She tells him that Carly had a one-night stand. Emily asks Hal not to make waves because Carly was pretty sure that the baby is Jack's. Hal asks whom the one-night stand was with and Emily tells him that it was Craig Montgomery.

Katie directs Craig to a great engagement ring choice, and then Craig tells the jeweler he'll come by later to complete the sale. On his way out the jeweler compliments Craig for being such a great customer. Katie hints that she knows about Carly's situation, but doesn't press the issue.
Rosanna gets the good news from Dr. Schiller that she won't have to schedule a follow-up appointment for another six weeks. Rosanna brings up Carly, and the doctor lets it slip that Carly will need to come in more often, now that she's starting her second trimester. This news hits Rosanna like a brick. Is it possible that Craig is the father?
Rosanna rushes home to confront Craig. Katie sees that she's no longer needed, and leaves the two alone. Rosanna accuses him of being the father of Carly's baby, but Craig comes clean with the truth. "I didn't sleep with Carly that night." Rosanna starts off on a very logical tirade, based on the lies she's been fed over the past few weeks and months, then tries to leave Craig in the dust. Craig blocks her from getting to the door, then he takes the phone out of her hands as she tries to call security. He sternly says, "You are not going to leave until you hear what I have to say. Carly was desperate, and needed to be rescued." Rosanna asks him if he knows who slept with Carly. Craig says it was Mike. Rosanna soaks it all in, and tearfully says, "You know I can't imagine anyone feeling like a bigger fool at the moment than I do." She turns and walks toward the door. Craig drops his hands at his side and says, "You know, I do...I do love you." Rosanna opens the door, turns around, and says, "Yeah...you just don't know how." She gently closes the door and walks out of his life.
Outside Craig's suite, Rosanna calls Mike on his cell phone and demands to meet him at Java ASAP. Molly hears that Mike is talking with Rosanna and takes the phone away from him. Molly tells Rosanna that she won't need to buy back her old apartment after all because she and Mike "are really very happy at the lake." Rosanna tearfully dismisses her enthusiasm by saying, "Well, I'm just thrilled for you...would you please put Mike back on?" Mike gets back on the phone and Rosanna grits her teeth and says, "Meet me at Java, or there will be no mercy for you!" She successfully pulls Mike's strings, and hangs up the phone.
Jack is confirming his travel arrangements at the station, when Hal walks in. Jack is happy to pass along all his open case files to Hal to handle while he is away.

Carly and Emily arrive at Dr. Schiller's office. The doctor is surprised to hear about Carly's travel plans. Carly realizes that Rosanna spoke with Dr. Schiller in the morning and worries about what was said between the two. Her suspicions are quickly confirmed when the doctor tells Carly that she told Rosanna about Carly being in her second trimester. The doctor walks away, and the news starts to sink in. Emily tries to comfort Carly, but Carly thinks it may be too late unless she can "stop my sister from destroying my life!"
Craig calls Carly's house, and Molly answers the phone. He doesn't wait to confirm that it is Carly he's speaking with and says, "Carly, we have a problem. Rosanna knows everything."
Mike meets a rigid, frigid, and jilted Rosanna at the Java Café. He says, "What's this all about?" She sizes him up as he takes a seat and says, "You got Carly pregnant again." Mike can't believe, or doesn't want to believe, what he's hearing. He admits that he slept with her, but "that doesn't mean the baby's mine." "It does if she's three months pregnant. I spoke to her doctor." Mike's jaw drops as he absorbs the truth.
Rosanna fixes her eyes on Mike, grits her teeth, and spits, "So, why aren't you smiling? You're going to be a daddy."
