You're already on her good path, when she stays at the police HQ. To unlock her CG scene, you need the event with the thieves guild from the previous update:
"New events for the Thremten thieves guild. It starts at the guild when you talk with Flaire. It requires that you advanced the main story to the point where you talked with commander at the Whitestone Citadel to get access to the Dhranholl mine for Katryx Ore (during the events to defeat Lace), you need to be either on Moriko's good path or when you raped her you need to have her second sex scene (which happens at the thieves guild), and you need to finish the events where Jenny was arrested and you investigate with police officer Nori to release her."
