As Sami and Lucas entered the DiMera mansion, Sami uttered that she couldn't wait to put her next plan into action. Lucas was surprised that Sami wanted to tell Victor that his grandson and wife were "going at it" behind his back. Lucas urged her to forget about it listed her blessings, including that she now had him to rely on. Cassie bounced into the room as Lucas left and demanded to know who had invited Sami into the mansion. A defensive Sami pointed out that Cassie did not belong there either because she was no blood relation to Tony. Cassie refused to let Sami bully her and spun around to leave as Lucas came back to the room to find out what the commotion was about. Sami blamed it on Cassie and the two agreed that she was a disturbed person. Lucas went on to say that he believed that Cassie was jealous of Sami for dating her father and then hanging around Lucas. Sami muttered that Cassie should watch her step or else she would end up with nothing. When Lucas prodded Sami to find out why she said that, he joked that they had everything because they were DiMeras, to which Sami said, "No they're not," under her breath. Before he could force Sami to explain, Rex appeared in the doorway. Sami left and Rex showed Lucas his plans for an explosive and told him that he would need complete access to Tony's bank accounts to finance his project. Lucas explained that he was in charge and refused to give Rex a blank check. The knock on the door was Bart who told an irritated Lucas that he had tried to see Maya to get the coordinate to find out the source of the mystery substance, but security would not let him see her without approval. Rex asked Lucas to give him the coordinate and he would find the other one, but Lucas declined and restated that he was left in charge. Rex angrily stomped upstairs as Bart left. Sami reentered the room to talk to Lucas and Cassie wondered aloud how to keep Sami quiet about the fact that she and Rex are not DiMeras. Meanwhile, Sami listened to Lucas talking on the phone about finding the source of the mystery substance and questioned him stating that she loved mysteries. She also said that she knew some DiMera secrets. Lucas said that she shouldn't overwork her voice and that he was taking her home to bed. Instead Sami asked Lucas to go somewhere with her.

While Rex brooded about Lucas being left in charge in Tony's absence, Cassie knocked at the door. Rex congratulated her on the charges against her being dropped and she began complaining about having to do community service. She made fun of his experiment and then found a picture of Mimi and told Rex he should quit moping around over her. Rex ignored her and went back to testing the sample of the mystery substance he had obtained from Bart. He explained to Cassie that he had to have all the answers before Tony got out of the hospital. Cassie taunted that he only wanted the answers to prove his loyalty to Tony even though he wasn't even a DiMera. She then raised the point that Mimi knew the truth and wondered how long she would keep quiet. Cassie left to take the picture back to Mimi so that Rex could start healing from the breakup. Soon Shawn arrived and persuaded the maid to let him see Rex. He paused outside the door and heard Rex talking into his tape recorder about the how the substance was a form of dynamite and was more dangerous than previously thought. Shawn left instead of talking to Rex and called his dad to tell him what he had found out. Rex took a quick swim and came back to find Mimi in his room waiting for him. She explained she was only there to make sure he was all right and tried to leave. Rex told her that if he solved the mystery of the substance he could be the most powerful DiMera ever. She reminded him that he wasn't a DiMera. Then he told her that he loved her and that was all that mattered. They kissed and Mimi melted once again as they went to bed. Afterwards Mimi inquired as to what Rex would do if he had to choose between her and the DiMeras. Rex said he didn't have to choose and a distraught Mimi got up to leave.
