Talk:Arthur Hastings/@comment-1628620-20151116052256

We might mention that Hastings' character evolves a bit between Styles and Dumb Witness. In Styles, he's very much the idiot assistant, completely taken by surprise by Poirot at every turn. But in Dumb Witness, he scores off Poirot several times, and proves that when it comes to understanding Poirot's particular psychology, he is very much Poirot's equal.
