if that's about the Drainfly, you should walk up to the Church of Qir (in the Tech Boulevard area) and talk to Corpi and purchase a Chitterspeech skill item, then go to the buy skill tab and buy it from there so it becomes permanent. and then you try to talk to her and new options will appear. then inspect her and keep talking to her until you convince her. just buying the chitterspeech item didn't work for me for it didn't appear on my item's list.
