you basically have to pick choices that are more "soft" and Submissive (Like apologizing to Katari, Losing too the Sub-Guh'Nir at least 2 times and choosing to stay longer those two times, recruit Bradley the first time you get a chance too and talk to everyone afterwards, forgiving Rylan and talking to Katari afterwards, choosing to get cummed on the face from the lizards in the ship, etc) There's a lot more then that so you have to do a little digging too.
