Theo/Pansy
Theo had managed to exit the living room without laughing, but it was a close thing. He'd been upset initially, of course--it was his little sister, and the situation had been rather sexual in nature from the outside until you got close. And he still wondered--Thomas rather looked like he was half in love with Amy and she with him, if people that young could actually make such claims.
But really, he just had to share the situation with someone, and his first thought was automatically to Pansy. He wasn't certain of where she was in his home, though she was welcome anywhere. It took a few minutes to find her in his library, wandering around.
He watched her from the doorway for a moment, one side of his mouth turning up a little higher in a slightly lopsided smile. She was beautiful to him.
