Yes, Miles-fucking-up-and-not-yet-realising-it is difficult, because it was really, really obvious from the moment he got the recall that the jig was up and yet he still carries on and digs himself even deeper into the hole. Which is obviously necessary for the plot, because he needs to hit bottom so he can turn things around, but it didn't half make me want to slap him round the head with a clue-by-four.
