I have always loved the idea of Roose being ridiculously judgmental about, say Lannister incest, while he's doing...well, what he does. "My wife may be 15, but at least she's not my sister!"

I still have to write Euron/Roose. One day.

And everything that he wears is the Hot Topic type clothing and he has a black rose or some equally ridiculous prop. Seems like the rest of the Greyjoys would go to biker bars.
