I meant the point after, in the previous episode, where Daenerys decides to obliterate King's Landing and in this episode where she's laying out her project for Westeros. We never got very much of her in this role, where she's now seen as a villain by the audience and the characters that had championed her cause before. It seems barely an episode between that turn and her getting knifed. Most other people on the series who were exposed as villains got a lot more episodes to chew the scenery in that role.
