When Aerion was first sent to Lys by his father, he was furious. Aerion had every right to be angered at the puppeteer's threat to House Targaryen and he had every right to challenge that oversized oaf called Duncan.
But it wasn't all bad, as Aerion came back to Westeros with a wife. A beautiful Lyseni woman, who clearly had Valyrian blood. Aerion was quite pleased with his bride, and due to him gaining her, all his fathers 'crimes' against him were forgiven.
Aerion and his wife were now sat at the dining table in the dining hall of Summerhall with his father and two brothers. He was eager to introduce his wife to them.
"None of you will have a wife such as this."
Aerion's comment was targetted towards his brothers, a smug expression on his face. If he wasn't being his usual arrogant self, his brothers might have believed that he was a doppleganger.
