I believe that The Architect is a lot more like a human than he realizes. He’s curious of human emotions such as love. He’d want to know, yet, since he is considered a “monsters” in this world, he’s afraid to where that could lead.
Yet, I believe if someone tainted as him, such as the Warden Commander, wanted to show him the meaning of feelings, despite fear, he would try.
Well, technically…if the Architect ever wanted to try it, Utha has been around him for a long time, would not die from contact, is sentient and capable of returning affection, and they appear to care about each other in the game. And even though the Warden Commander is more attractive than a dwarven ghoul, somehow I don’t think a darkspawn (even one with a sense of aesthetics, which the Architect obviously is - just look at him) would have an understanding of it necessary to care, or even notice.
But yeah, if for some strange, strange reason the Architect was a romance option for the Warden Commander, of course I would :) He is fascinating. The very concept of him, what he is and why, what he’s been up to and what his plans might be, is fascinating.
