You don't know the god damn Lannister sigil. So yeah, I'm pretty confident I'm smarter than you in the very least. I definitely got that pretty quickly watching the series itself before started reading the books.
i knew the lannister sigil. i knew most of the ones on the list earlier, especially the main ones.
Just pay attention instead of posting during the episode.
i didn't post during the episode. even had to tell my wife a few times to shut her mouth before i shut it for her so i can listen to all the dialog
