Of course there were potential indicators that Camille plausible could be a love/fuck interest. Unlike the vampires, she was introduced and has several scenes with the MC. And unlike the by necessary supernatural elements that come with vampires, the game features comparable sexual available woman in Camillas range, so applying this already existing element on her is not as implausible as applying supernatural elements to this ordinary world that requires science and medicine to keep the daughter alive (hopefully someone chims in and argues that her medical cure could count as magic).
This is getting a bit ridiculous. It's like saying there is blood in game, therefore vampires are totally possible.
Not to mention that most people irl don't believe in supernatural, but can you say 100% for sure that it isn't possible?
And I'll even use your own argument (again) and say it's just a game, so why do you think supernatural is so out of possibility? Again, by your own logic, we are early in the game. MC could very well wake up some day and realize he was possesed by a demon that made him cheat on his wife.
Can we please keep this discussion on a porn game and refrain from insinuating that anyone here applies the games logic to real life? It's very rude and needlessly personal in an otherwise very impersonal discussion.
Why? Because it's inconvenient for you? There is plenty of real life inserted in games, even porn ones. Otherwise story wouldn't be as compelling. Games with best stories aren't the ones where you happen to be the only guy in a house full of hot women and in two days, they jump on your dick. No, the ones with good stories are ones that are more believable and closer to real life. Yes, it's a porn game, but that doesn't mean there is absolutely no need for good dialogue, consistency, well written characters etc. You can clearly separate well written AVNs from the ones that are just there for sex mostly. Besides, it doesn't even need to rely on real life. Thinking just because there is an attractive woman in game, she should get banged by MC, is just a strange notion.
If a character with a full model and personality and background is introduced and fleshed out, its far more likely that that character is used in sexual encounters to enrich the experience of the game, because implementing that character required work, time, cost, so it must have some sort of reward, effect.
Have you consider a possibility that she is "fleshed out" for the sake of Cooper, to make his character better, more realistic, relatable etc? I actually notice and am bothered by games that have pretty good story, yet MC is the only guy in the game or only one that is being seen by women. It makes story less believable. It's not a deal breaker, but it sure doesn't help make it better.
Does this 100% refute that she can't get sexual content? No.
We are talking in circles. I already told you many times it's not a question about whether it's possible, it's question about why should it be? And you keep going back to "hot girl, so gotta/should be there for sex".
Going by the current state of the game and story, I just see no reason why we should want that to be a possibility. I like the way their relationship work between them and how it works towards MC. It's not common to see that in this genre.
