Reading through your explanation I can only say that I actually agree. It literally didn't occur to me at that point, because I obviously wanted to go for a relationship with Kate & my only concern was and is if things go well with Sarah & Kate there. But you are absolutely correct that the unhappiness about the lack of choice in regards to getting intimate with her going that path is completely warranted & I back that it leads to the problem you describe, despite me personally not having a problem with it since it's what I hoped for.
Actually that is the same problem I have with Razaphel, despite not disliking him otherwise, but the lack of a choice in regards to intimacy with him if I wish to hear his side of the story made me not go with that. That's part of what led to my dilemma and relative dislike for the mage route (which just means I liked it the least of what I saw so far, but still enjoyed it, just for the record). Generally I would have a major problem with the exact same things you point out if I happened to dislike a character too much to go after them intimately/romantically and would be either forced to sit through it or ignore the complete route.
I admittedly will have to think about what you write about the exact consequences for Kate's and Sarah's characters due to the way the whole thing is handled. I don't disagree, but I have to really point out that I was relieved by the lack of angst and further drama after choosing to forgive her, so I can't really say I would want for that to be changed. I do think, however, that it would most likely really add to the whole thing if the player had control over how things are handled by Sarah there, as you suggested beforehand. Since the story isn't finished yet I feel like I shouldn't rule out the possibility of Kate getting a big redemption moment later down the line, which would be really cool (as long as it doesn't kill her without any chance for the player to prevent that). Personally I would really welcome though if (in case the Dev feels like changing some stuff) the option to treat Kate the way Sarah does do now still remains for those who prefer that. 100% support from me though in regards to Sarah trying to really understand Kate & try and support her in overcoming her problems. That would be really great.
I gonna have to finish the route to the current point though I think before I can really discuss the details you brought up properly though, I'm sorry. x.x
Thank you so much for your response!
First of I am relieved and ever grateful that I managed to communicate my point in a way that can be understood and empathized with. Hopefully my past response was enlightening to you like yours was to me and this one also.
Secondly, on the topic of Razaphel I also agree 100%, were actually kind of opposites yet similar funnily enough. For me picking to have sex with Raz was the obvious optimal choice since I thought at the time even if it was transactional, it was sex with a non-female being that you can opt out of, that leads to interesting revelations and character interactions and as such more content. I thought, "Why on earth would I or anyone would refuse this?" I never considered that the transactional part of the exchange is coercive and a turn off for other people. I didn't think it was a problem because you can opt out of it. I guess that goes to show that personal preference makes you biased lol. Thank you for giving me this perspective.
Thirdly, I'm glad that we came to a mutual understanding about Sarah and Kate's relationship despite our disagreements, you brought up a lot of interesting points that I didn't think about, thanks!
I do think that for Kate's redemption to work it needs to be something that is universally canon to the Warrior path regardless of the path you choose and something that she commits to regardless of our decisions for it to be meaningful, as counter intuitive as that sounds. Her actions are so narrative defining after all, her redemption needs to be that way too, a defining and unavoidable key part of the plot and her character. Her redemption arc being an addition will add a lot to the narrative I feel. This would especially enhance her own path and make it palatable.
(Besides, with the way Kate is written she already has the spotlight anyway, for me she comes across as an author's pet, which is not a bad thing on its own, but it does mean that she has immense pressure on her to be palatable to the audience due to said spotlight and needs to work well with the other characters more than anyone in the story).
Imagine after Sarah wins her mercenary test, regardless of the training path chosen, Kate comes to Sarah with some of the jewels that she traded away and managed to regain, this token of good faith automatically leads Sarah to be open to listen to her. Kate then explains why she did the things she did and she explains how nothing about her experience can justify her betrayal of Sarah's trust, she then vows to the gods to conquer her addiction, make things right for Sarah, and become her sword and shield. Promising to return every single thing that she took from Sarah and more, not just her jewels which she intends to return to her or failing that pay her back a thousand fold, but also her kingdom and her people. And she does this without any expectation of forgiveness from Sarah, desiring instead only for Sarah to forgive herself for taking her hand and believing her lies, taking full accountability for her betrayal and giving Sarah some measure of peace. And on top of it all, regardless of Sarah's and our choices to respond, regardless of whether we choose to forgive her or not, she commits to this path that she willingly chose for herself of her own volition and she actually follows through with her words. Conquering her addiction, becoming Sarah's true supporter, the friend she was always meant to be. What do you think? Is this good enough?
I feel like doing it this way is the optimal way, since this a story about survival having an ally is invaluable and it would give the audience a pragmatic reason to care about Kate regardless of our feelings towards her. This would also justify her author pet-like spotlight in the story by making her palatable to the audience. Doing it within the time frame of the first part of the Warrior route would be the most ideal I think, any later and it ruins the goodwill of the audience towards her and festers resentment towards her, which is not the kind of thing you want when you want to make a character central to a story.
