Right. It was viewed as an incurable disease, which ultimately led to the genocide and the scorching of the city. Nobody inside or outside could offer any ideas regarding a cure. It would be strange if "some person" snatched a sick girl from a closet and somehow saved her. Let's keep in mind at that point Flamingo didn't know Law, so he couldn't have saved her (assuming he could have somehow cured her) in order to blackmail Law later. I'm not saying someone saving her couldn't have happened, but it better have a good explanation. Something a bit better than a colleague from the outside deciding to come help their old man and happening to arrive just then.
