Yep! You have to talk to fawn, , revisit her again, and talk ideas. after that , go talk to Arlene (fish woman cop) and talk to her about it, you should be visiting fawn with Arlene to discuss how to recue her, if you are done, talk to either Lin Lin or Sammy about the guard's scaedue (absolutely do it helps a lot.) and i think you can continue from there.
