Since Gomez was featured (somewhat) prominently in her two episodes, I'm guessing they intended to bring her back Lycia Naff in future episodes. Did something happen behind the scenes that I haven't heard about?
The TNG Companion says that she was written in to the two episodes for the comedic value, and then dropped. This implies that whatever little comedic asides the writers had tried to do they weren't happy with so her character was dropped.
