You don't strike me as someone who particularly mannered, so I didn't speculate on it and waited for Wraith.
I think everyone should pay attention to what gandalf said in his second post. The name of the House is irrelevant except when the people are from House Argelev which means they are heirs to the throne. Do they fight among them, do the loyalists need to keep only one alive, do they have protective abilities ? Those are relevant questions, unfortunately I don't see a way we could get that right now.
However, I am fairly confident that DX know enough town flavor to prevent us from lynching him D1. Even though Wraith says that flavor is irrelevant, he might have forgotten someting. He mentionned a name that I have as heir to house Argelev which should from my PoV prove his innocence.
