The Orator Poses. My GOD does he or she pose. Portentious, dramatic, lecturing. We are talking major literary works each pose, with enough to take on board and react to that the scene slows down to two rounds of poses an hour. And worse, this one is infectious, causing everyone else to match them in an effort to share the limelight.
Leeches love 'em.
The Wannabe Subtle, this one. Turns up on your carefully crafted game. No matter that your world doesn't allow such a character, or it doesn't fit with your detailed theme. Which, of course, they've never read. And it's utterly facist of you not to allow them to play exactly what they want.
