was this during the quest when you get her? or afterwards? at the moment I'm back at neutral cause I was going to go dark until I read the replies on here. I know when I recruited her I didn't choose any of the "we can fix the empire from the inside" options all of my responses were telling her to embrace the dark side and I fought her a few times and even now when I talk to her she says that my path is uncertain which she never did before so I don't know if lowering your alignment did that or if its just something she says.
Also, does anyone else find it weird that (apparently) you have to pretty much kill everyone Jaesa loves and cares about in order to the dark side and join you? I mean I'd understand turning to the dark side after that but why join you and then go all bloodthirsty sex crazed maniac over you? It just doesn't add up, in every other fallen Jedi/light sider turned Sith/dark sider related story I've ever read there is a progressive fall due to uncertainty, paranoia, lust for power, etc, not a complete personality change the instant something bad happens.
I really don't think that Bioware put much thought into her story which really doesn't make sense considering their rep with romances. With romances you have to keep grinding and grinding by giving gifts and saying the right things to get affection and it takes awhile to get them to even acknowledge you in that way and if you did everything right then you finally get to have a relationship/sleep with them and I would think that turning someone from light to dark would be the same way and visa versa. Granted you do get an entire act to choose how your actions will affect her but it really is a poor attempt cause you never even see her until your about to recruit her, its not like you can influence her in any way directly. And honestly, I didnt even know she was a companion until I had the option to tell Malgus that I could corrupt her. so I looked it up. Before I had just thought all of act 1 was just another one of Malgus's BS missions that I had to complete to get to the real story.
I really love this game but its playing out far too much like Mass Effect/Dragon Age and by that I mean every one of your actions or choices affects something in the long run, which I love except, in a normal Bioware game if you want to experience everything you make save files so you can reboot to see the different choices you make or just make a new character altogether. And I would do that in this game except... for the mmo part of this game. It takes a long time to get from 1-37, I've maxed out 2 crafts, I have a crapload of credits from crafts (which I could just transfer but still), I have a bunch of hard to get titles, and most importantly I have every single datacron up until Taris which I sure as hell dont want to get again. So to give up all of that just to get a personality change which should have better developed is totally not worth it for me but it is a shame, oh well.
