Dude you need to chill on you're remarks, I said I know it's a game and what it was meant for. All I said it would nice if these developers tried something new and give dude some backbone. In every storyline or game they don't have to make the guy go along with everything. Another thing these developers or most want you to put yourself into the game, because that means you'll come back to play and hopefully buy it. They are something I mess with during downtime on the road, it's better then watching TV. Talk about having to wait on game updates. I'll find a good show and in 2 days I've watched all the episodes now I have to wait a full year for an update.
While I agree with you that it would benefit the writing and the story overall if there were more conflict and tension coming from Ethan. And him at least trying to put his foot down if there is something he feels a bit uneasy about.
However I only see it blowing up in his face and making things escalate even more. Otherwise the route would end, or branch into another "redemption of Ethan" route. No thank you, no more alternative routes. There is already more than the developer can reasonably handle.
Nat can play so many angles if this scenario were to happen, "this was your idea to begin with" , "what about my fantasies, I have desires too".
Now if Ethan had a backbone here, he would give her an ultimatum, and if she didn't accept it, he would leave.
But this is the cuckold route, even more so if you play the Ethan-submissive route. Ethan has no job and he has a hard time satisfying his wife in bed. It would make 0 sense for Ethan to suddenly grow a pair and take the reins, unless you are looking for some sort of a redemption arc, but if you are playing this route you probably aren't looking for that. In fact that would ruin it.
So Ethan would bend if pushed by Nat, she would probably be sweet about it and not super confrontational like in my examples above. She would just slowly try to move the barrier of what Ethan is comfortable with. But she does have a new-found confidence now, and certainly a new side of herself has been revealed thanks to Ethan.
So who knows...I could see her putting Ethan under her heel, if she wanted too. But Ethan hasn't really given her any reason to do that, so far. For the most part Ethan is extremely supportive of her every move. He only express some mild discomfort in his own head, never to her directly. And it's always followed by intense excitement.
But I agree with you, I would enjoy Ethan
trying to grow a backbone and starting an argument with Nat. But the outcome of that altercation is where we fundamentally have two different opinions, at least when it comes to this particular route.
