Unlike with the majority of people in the world, Blaise's amusement toward Draco wasn't malicious. Draco rarely, if ever, got the sharp side of Blaise's tongue, only the backlash when Blaise couldn't stand the rest of the world. It was, perhaps, a mark of Blaise's fondness that even if upset with him, he didn't flay Draco verbally.
"Make her feel special," Blaise said, encouraging this route of thinking. "She'll love it if you do something you've obviously put this sort of thought into."
Blaise chuckled. "Not ridiculous, I think," he drawled. "She's sexy as hell, and you'd be blind not to realize it. And she's made her own want of you quite plain, in her way." Her almost understated Slytherin way, sprinkled with a bit of boldness that was pure Millicent.
"Mmm," Blaise made a considering sound. "Bits and nibbles? Pâté, caviar?" he suggested. "With wine, of course. Simple but elegant, easily kept." And easily shared and very nicely fed to one another, if it came to that.
