''Gryffindor.''
''Yeah,'' Kylo agreed. They watched Gwen walk away, unaware of the two men perched high above in the beams of the vaulted roof.
''Ravenclaw,'' they chorused as Gaius passed a few minutes later.
Their next subject came.
''Slytherin.''
''Gryffindor. Why do you say Slytherin?'' Kylo asked.
''Because Leon's the only one besides me and Arthur who's survived everything since I came here. He's got to be a Slytherin. If he was a Gryffindor he'd have been a little greasy spot years ago.''
Leon looked up as he walked below, squinting, but didn't spot them. ''I guess you're right,'' Kylo conceded. ''No one else has looked up.''
A few minutes later Rey and Gwaine wandered past. ''She's a Puff,'' Kylo said, almost affectionately.
''Yeah, probably. Or else a Gryffindor. Gwaine's a definite Gryffindor. He pushed me off a building once into a haystack and said it was fun.''
''Some Gryffindors are fun, some are just annoying, and it gets really infuriating when they're the same person.''
''Tell me about it,'' Merlin grumbled. ''Hey, here's Arthur.''
They watched him pass.
''Hufflepuff.''
''Yep. He's even the house colors.''
''I know. It's adorable.'' Merlin choked. ''In a totally non-romantic way,'' he hurriedly corrected.
''Chill, dude. I know. You're not gay. Not that it really matters either way.''
''Good.''
