Draco had moved on from greeting her sister, and was on his way to greet another guest - he could play the role of host well if he had to - when he saw Astoria come in. Their recent conversation through those damned journals was still a bit amusing, and very few of his conversations on them had been. He remembered her enough that he detoured her direction and grabbed another glass of sparkling cider from one of the passing trays.
"Astoria," He said in greeting, and his smile was always at least half a smirk. "I was wondering if you'd allowed your sister to come alone."
