Ginny blinked, and she took recognition of the fact that she blinked, because at that moment it was all she was doing. What he had said actually made sense... and Ginny knew that it was true. Hermione (and even Harry that wasn't truly muggleborn) were extremely capable wizards, but there were things about the magical world they didn't grow up with. This was something she had always known, but to hear it from Draco Malfoy...
"So you're saying you don't believe muggleborns to be inferior then... that's good to know."
Ginny felt that raising an argument on how 'princess' was not a suitable name for her wouldn't be in their best interests at the moment. After all, how horrible would it be for the movement to die, because he had once called her princess.
Ginny took a sip of her tea, "I suppose that shows how much you still don't know about me."
No... she could save that argument for another time... or better yet find something slightly demeaning or likewise to call him.
I do like that option better.
She smirked, "So, we have this thing we're trying to control for a greater purpose. Do you think we've had any success so far?"
