Vainamoinen: Assumptions, assumptions.
In Dreamfall, we've seen how a man who grew up in a matriarchial society listens to a woman who talks to him in a voice of authority, and he senses a strange familiarity.
The first isn't surprising, the second isn't love.
Kian did praise some of the women in Dreamfall, again, not surprising considering his cultural background, but he never revealed his sexuality.
And of course due to the Lady Alvane conundrum, people got hell bent on the Kian/April romance idea back in 2006, and the thought lingered on. But it should have become clear by the first scene in Chapters already that it's not happening. :)
Still I don't think in a series like TLJ (where there was already a gay relationship) there was the need to hide the fact that Kian is gay.
I still think that in Dreamfall TLJ Kian was not gay. His character was just a warrior not interested in love. And when he meet April (that was an enemy) he start to develop some feeling.
Also if many people still cannot believe that, it is because is not clear at all.
Finally they decide to ask you if you want to kiss Anna... why? I have some hypotheses:
1. They had in mind a romance
2. They wanted to make fun of the player
3. They wanted to reinforce the idea of the warrior no interest in love
4. They wanted to create a contrast between his love for April (that was dead) and the love for the new character Anna (that was a spy).
When it is revealed that Kian is gay? During a conversation at the beginning of the book 3. It is no longer mentioned (except during a dialogue with Crow) and it does not in any way change the story and it is a question not connected with anything in the game world...
To me it seems clear what happened ... They did not know how to develop the story of Kian, they could not afford more paths (think also that book 3 is really short), they did not want to resurrect April... so they decide to create a new sexuality orientation for Kian... why? In this way they saved a lot of money by creating a mandatory path, they exonerated themself from making interesting Kian, they were able to get the unconditional support for raising a social issue (accusing anyone who disagrees to be against gay).
It may be that I'm wrong .... but in my opinion, Kian gay, was last-minute idea, an idea not at all obvious until book 3, an idea very convenient (for them).
And since this is a game I'm sure assumptions on a game of 10 years ago are not so wrong.
Most video game characters do not say if they are gay or not, because most of the time if there is no romance there is no need to say that... but in recent years it is fashionable to say "who you are".
Too bad there was no need to do that in this series since already in TLJ there was already a well-written normal homosexual relationship.
Kian, to me, seemed a forced character.
