Oooh, like who to put on the throne of Orzammar. A Brosca has good personal and political reasons to crown Bhelen; an Aeducan can be played either way politically, but in general would not want to see their treacherous little brother within a mile of the throne. Lots of potential for conflict there, and if it's the Aeducan who changes, they could be brought to see all the reasons Bhelen is best for Orzammar and the Wardens. Hmm.
