okay, so I am going to repeat it again...
I am not disagreeing, but I think it just needs to be toned down and given nuance a bit.
And I'm saying that your dialogue options effectively tone her down and that there's already nuance in the game. She's cordial with the player in her own gith way, and refers to Tav as an ally in an instance or two.
Try playing as a Gith and this all becomes way more apparent.
