Draco got away from Troy as quickly as he could. He had no intention of watching more crazy wizards. He'd had enough with his aunt, but then he could see her get ready to go out.
The glamours weren't drastic. Her hair was a light shade of brown. Her cheekbones less pronounced it. It was enough to make her unrecognisable unless you knew what you were looking for. They were in a pub, Draco couldn't see enough to recognise it. Millicent was at the bar, a drunken man was hitting on her, spitting as he talked. Draco could see her hand go to her wand. The man deserved what he had got, but then the Mudblood was there, all smile and politeness, getting the man out.
The flirting afterwards was pitiful, or so Draco thought, but Millicent seemed riveted. He watched them get up from the bar, and he pulled out before going any further. Sex with a Mudblood wasn't something he wanted to see.
Draco looked at her. "Do you remember now? Or I can go back in if you like." Please, don't, he thought but didn't say, giving her the same pleasant smile.
