I always play and make sure to kill Juhani because she annoys me, (but I do it in a way that it doesn't count as a Dark Side action). I hate her face (cat-like) and her voice, it's like a drunk man's, it's annoying when she interrupts the dialogue.
She's on Korriban, I think there will be additional dialogue options, like "Ha-ha, I'm Revan" or something else.
Siv, I like to complete Kashyyyk first.
Where do we end up when we save the world?
