However, Nick only went back to Eve in an effort to help Mindy because Nick himself had come to the realization that Eve was obsessed with Mindy and needed help. Eve acted and dressed like Mindy and had broken into Mindy's medical records as well. In fact, Eve was the one who had drugged Mindy's bottle of water and manipulated her blood results so that alcohol would be found. Unfortunately, Eve overheard Nick telling Mindy the truth and went crazy. One evening during a storm, Eve hid in Mindy's closet and when she was about to cut the hair off a sleeping Mindy, Mindy woke up and Eve knocked her out during their fight. Nick, who was searching for Eve, found Mindy but Eve injected with a drug and threatened to jump off the observation deck, until Ed Bauer talked her down. Now Eve went to a psychiatric center for treatment and Mindy, at Ed's urging, didn't press charges against her. Though Mindy no longer believed in a future with Nick, after a few weeks, they reunited. After Eve was released from the sanatorium, Nick caught Mindy's ire by trying to help Eve start a new life. Mindy still saw Eve as a threat in their lives and Nick's willingness to help her lead to many arguments until Nick decided they should separate for a while. At the same time, Mindy befriended cop Macauley "Mac" West, who had once investigated the murder of a man named Davenport for which an innocent David Grant had been imprisoned. Since David was now wanted for the murder of Vinnie Morrison, Nick investigated to help David while he warned Mindy about Mac. Mindy was certain that Nick was only jealous until she learned that Mac was apparently in touch with Vinnie's uncle who wanted avenge for Vinnie's murder. As a result, Mindy cooperated with Nick to get information against Mac, even helping Nick to break into Mac's apartment. In the end, it was discovered that Mac was covering for his old girlfriend, Norrie Ryan.. After Nick found Norrie and the police finally resolved the case, Mac confessed to Mindy that he had fallen in love with her and asked her to move with him to Chicago but Mindy refused. After Mac left, Mindy and Nick reunited. Not long after, Alex returned to town. Although they still couldn't stand each other, Mindy tried to make peace with Alex for Nick's sake and let her stay at the boat house since Alex was homeless after Jenna Bradshaw and Roger had taken over Spaulding.
