Complaints about Clara is a determinant ministry quest.
If Carl Stein refuses to evict Clara Jacque, Alloisius Shpak will move out of his apartment, leaving Clara to owning the apartment and all of his belongings. The ministry will call you about her once Alloisius is no long marked as a tenant in the apartment building, even if he has not left the grounds yet. Talking to Mark Ranek and Rosa Ranek is optional, but they will mention Clara flirting with Mark. Carl requests $5000 or 500 reputation in order to evict Clara through dialogue. However, he can simply report her to finish the quest. Paying her to leave will cause her to take Alloisius's Cruise tickets with her, making it impossible to help Klaus Schimmer and Maria Schimmer leave the country alive.
