Detective Dutch Wagenbach was initially attracted to patrol officer Danny Sofer. Taking advantage of his attraction, Danny manipulated him into helping her pass an exam that would have resulted in her promotion. After Danny rejected his advances one night after Dutch visited her home to help her prepare for her exam, Dutch lingered long enough to see his nemesis, Vic Mackey arrive and passionately kiss Danny. (Dutch's reaction to this, a muttered "You've got to be shitting me!" quickly became a popular catchphrase for fans of the show and has become a running gag during the show's run, used by various characters when they witness something shocking.)
Dutch would ultimately call Danny out on her manipulation in front of the rest of the Barn, when Danny tried to schedule another study session while Dutch was deep in the middle of an investigation of a recently-murdered child. The two would eventually settle their differences and apologize to one another for their mutual bad behavior. The two remained close friends as Dutch has continued to mentor Danny unofficially.
In Season 6, after Dutch watched his longtime crush, Tina Hanlon, have sex with another man, he leaned on Danny for support. As for Danny, she began to see a more mature side to Dutch, who responded to Tina's apology by telling her in a fatherly way that she had no reason to apologize. Later, as Dutch comforted the nephew of a homeless man who had died alone, despite a family which loved him, Danny realized that she had feelings for him. When Danny later found him in the locker room, sobbing over the homeless man's death, she put her arms around him. The scene ended with them kissing passionately.
