She has a few interactions, but you generally come across as a moron when interacting with her. Rather than assume you actually know anything from growing up a gith, the game has you ask basic ass questions. Your character SHOULD know about purification, and be able to discuss it with her. Instead you ask her what it is, and are chided for being stupid. Same with discussing Vlaakith. There's no "Another glorious day in the service to the Lich Queen!" but instead "Derrrr.. who is our god queen again?"
Also, she never gives approval for you giving Gith responses. This feels like a bug, as though they are dialogue she would give during an Origin playthrough and Laezel wouldnt give approval for herself. Regardless, it should be changed.
