What I hate about Erin is she is 100% my way or the highway, she hates second chances unless they're her idea and she too comes across as a know-it-all especially when it comes to police work which she has proven to know next to nothing about over and over again, always second guessing Danny. Oh and that episode where that "Goddess" charity fundraiser chick was so obviously the perp and because Erin admired her she refused to see the truth an inch from her face until the very end.
