The way I've had it explained to me Anaris, is that because Luria is the aggressor against Dhara, it is the one responsible for the lack of definitive action against Aurvandil. Not to mention 'responsible' for multiple thousands of CS being unable to even show up down South.
I'm presuming that something along those lines is what half the allegations against Sevastian are about.
Regardless, I'm not fond of that line of thought, and tend to agree with you. Dhara is being obstinate.
