Well, well, well.
I told Rylee that "there is no us". What the hell was she thinking? that she could run off with a Sith? She is clearly a weakling and unworthy (unlike Darth Lachris ofc).
When I saw her all sad and stuff I was wondering if that choice had let me miss out on anything important, like a companion or something. So I went to check the forums and found this thread.
When I went into that part of the quest I was fully anticipating (and had made up my mind to follow through) that the quest choices would give me the option to sell out the two weaklings Rylee and Destris to Darth Paladius in exchange for the artifact. I think they got away lucky.
You Rylee-loving people need to get your dark side act together...
