I'm going to go out on a limb...
According to IMDB, Maisie was played by Sharon Thomas, she also played "pretentious lady" in season 2. the same actor playing two parts, would cause them to say "Don't i know you?", and would also tie them for third place. We don't know much about this character obviously, since she's not even given a name...
So is #10 "pretentious lady"?
