I agree with what's been said about the triss/geralt romance being well done until after the lighthouse scene where she leaves and never seems to acknowledge him as being her lover again...kinda disappointing. Leaves me wondering if I need to reload and start over but apparently everyone else is having the same issues. I'm not really familiar with all of the witcher series, and I just jumped on board for witcher 3 so don't hound me too much but I chose triss over yen due to the fact that she seems to care an awful lot more for geralt than yen. She kept a rose that geralt gave her, she's always been there for him and doesn't treat him like garbage like yen has in the first part of game. But in choosing triss, I don't feel the choice has been recognized by anyone else. Ya, yen is pissed but what's new. And I was upset when the scene at kaer morden when I finally unite Ciri, yen gives me a kiss and right at that exact moment triss comes in to see it and gives a bad facial expression...wtf, I hadn't been nice to yen the whole game and gonna get burned now? Lol, anyways, I feel there is no way to justify for that, you can't interact with triss even though you can talk to all the other characters. At this point I have no clue what to think of their relationship because you just don't get any signs. No hug, no winks, no smile...come on! The game is very well put together aside from the triss romance.
Welcome. Yeah your not alone. I went in from the previous books and games with a negative impression of Yen and a positive one of Triss so yeah definitely wasn't impressed with the way she drops completely off the map after Lighthouse and utter Yen focus in the middle portion culminating in the awful passionate kiss she gives Geralt right in front of Triss(who barely reacts).
Later there is an excellent scene which does give a bit of one on one romance discussion. The game as a whole seems to set the scene greatly in Skellige and Novigrad and then fail to address things in the later acts properly.
