One thing about Azur… I don’t think h was trying to be a dick after the piano scene. In fact, he pointed out that there are eyes everywhere–the MC (and A) are being watched. He’s not the mushy gushy type, so if he showed any sort of care at all about the MC, it’s something the ‘enemy’ can use against him (and the MC). When you’re in enemy territory, you have to be damned careful about what you let them know, after all. And he definitely sees his father as an enemy.
I may be off on this (Cara is the one to ask), but that was my take on it. And hell, you got more out of A than R, by far. Not that I don’t love R.
