I'm not very fond of Vette, once I was able to I was quick to replace her, she does not fit well with a Sith. She whines way too much, and most of the darkside choices I've found fall under one of her dislikes.
Sith are by nature cruel. Thus is the reason why my affection for this companion will forever remain low.
I FULLY agree... she just did not fit in with the Dark path I want to follow.... Dark Jeasa though, fits in just right.
