Halsin's romance feels totally rushed, you don't get anything until after lifting the shadow curse, then he tells you his rules, you can have sex and afterwards he decides to keep monastic silence (only broken when he sees the refugees/orphans, when he sees the opportunity to have sex with the drow twins) until right before the last battle and then you get the ending.
So, yes, Halsin is not really happening in act 3, his character in act 3 doesn't fit the one in act 1 & 2 and you get the feeling that the most important thing for him has been the sex after the curse is lifted.
Yet, I have to admit that the new kisses and animations are sweet, but I could've done it without them if they would've added more dialogues.
