Harry and Open
Harry had no idea what to expect from a party thrown by Gregory Goyle's mother. He still didn't even know why he'd been invited. Was this some sort of play to make the Goyle's seem legitimate? Harry knew there was nothing that pointed to Goyle's mother being involved in anything with the Death Eaters, but Harry trusted her about as much as he trusted her son. Which was to say, not at all.
Whatever he'd hoped to find, however, he was disappointed. The party was almost...boring, for a function attended by more than one former or suspected Death Eater. If pressed or under a truth potion, Harry might even admit that he found the Goyle's home...charming. He winced at the internal thought, and glanced around for anything suspicious. He took a large sip of the drink he'd been carrying around for show (and had covertly cast all manner of detection charms on before actually drinking it) for lack of anything else to do.
He was heading towards the back left corner, to a spot he'd picked out as having the best vantage point in the room, when he heard someone say his name.
