To be fair the last step isn't really "I'll just fuck off" its actually "I'm going to fuck you up" with how fucked up actually you get depending on how good you are at fighting.
However I actually like that scene, not as a bases for building NTR from, just for what it tells us about Rowan's situation. Essentially as long a Rowan is useful the twins can't kill him or (openly) touch his wife. Essentially they can't do anything what would make Rowan unable or unwilling to continue his duties. However, Andras is riding that line, trying to get as close to the limit as possible with out crossing over it, because they need Rowan to believe that they can and will do anything to him or his wife in order to keep him firmly under control.
It reminded me of something that happened when I was in Air Force Basic Training (boot camp) our Training Instructor (drill sergeant) was laying into our squad, yelling and threatening, and at the same time he was gesturing with a pen. Well the pen slipped out of his hand and hit one of other the trainees in the face. The instructor immediately stopped yelling and asked if the trainee was okay (he was fine) in a concerned voice. It was at that moment that I realized that despite all the threats and popular media depictions, the instructors couldn't actually do anything harm us. I mean I already kind of assumed as such on an intellectual level, but it easy to doubt when a guy with a arms bigger than both you legs combined is yelling at you, less than an inch from your face, about what he's going to do to you if you fuck up on one more time. The instructor wanted to make us believe they could and would do anything they wanted to us so that we woud keep following order with out hesitation.
In the end we are all just theory crafting and sharing our own head canon. The truth of the matter is that no media is as deep as the fans imagine it to be. When you have so many people pouring over a piece of media analyzing every aspect they are bound to find aspects or themes that are outside anything the handful of creators ever intended.
Personally, I think it is fun to over analyze media, I like finding meanings and themes hidden inside. But you have to keep in mind that you are in fact over analyzing it and there is a pretty good chance that the creator didn't put nearly as much though into what ever it is as you are. Although that doesn't necessarily mean that the messages and themes are not there, just that the creator didn't necessarily add them in deliberately.
For example, If I say something like: "
Andras represents toxic masculinity and his larger penis represents his position over Rowan in the masculine hierarchy." I doubt the writers were thinking "
lets add a character to represent toxic masculinity," but at the same time Andras is certainly toxicly masculine. By the same token from Andras's penis size we can question why it is that a large penis is seen as more masculine. Compare this to ancient Greek culture where a large penis was seen as barbaric and the idealized man would have a small penis. Indeed we have seen nearly a complete reversal in that barbaric behavior in general is seen as more masculine than civilized behavior. But from the creator's side it likely amounted to "
big demon gets big penis" and maybe some thought into emasculating Rowan a bit.
For me it works though, the their prologue scene it is clearly the definition of a hate fuck. Alexia is angry at Andras after finding out he tricked her, but she is still really attracted to him physically. In the heat of that moment the physicality wins out, but her angry emotions are there throughout. Once their finished though, whatever the female version of the post nut clarity sets in and she immediately regrets what she's done. Now that her physical needs met she turns to just feeling hostile towards him. But afterwards, Rowan isn't taking care of her needs, and she starts getting tempted by that demon D again, because while Andras is an ass the sex was really good...
Though I guess this is also just a fan filling in the gaps with head canon to a degree, jsut like what fihesog318 was saying in his post.
