Re: In Hogsmeade...
"My intention of relaying your suggestions myself, was to inform them they wouldn't have to consider assigning anybody else than me to accompany you to those events." Adrian wouldn't change his mind in that respect, even if Lestrange seemed set on either intimidating or impressing him with his power. It was hard to do either to Adrian, unless the other person was in an actual position to directly influence his life.
"As for any desire I might have to shag a man, it would have no impact on my apparent need to be introduced to suitable half-blood women, since I eventually would have to decide to marry one of them whether I want to or not. Isn't that so?" But Adrian wasn't here to start an argument or involve himself personally in this. He couldn't figure out what intentions Lestrange had though. The man seemed awfully interested in involving Adrian in the process of moving up in society.
"I am a Slytherin, but that's not the only thing I am, Mr. Lestrange. So I'll have to ask in return, why are you so generously offering me to take me along for your ... rise in society?" Because Adrian doubted it was actual generousity that was the motive.
