- Big-Lipped Alligator Moment: In the opening sequence, the Doctor and Clara are arguing about trying to meet Robin Hood when, out of nowhere, the Doctor produces a large spoon covered with an unidentified food substance (ice cream? custard? icing?), licks the spoon and then apparently puts the spoon away in his pocket. No explanation is ever given for why he's carrying a spoon around - long shots in the same sequence reveal no food in evidence, and it really does seem as if the Doctor puts the ice cream/custard/icing-covered spoon back in his pocket. Clara doesn't appear to notice (in fact the Doctor appears to lick the spoon with his back turned to her so she can't see). It is a truly puzzling moment. A few minutes later we do see the Doctor use a spoon in his comedic duel with Robin Hood, but the spoon is not only completely clean but it looks like a different colored spoon than the one from earlier!
- Bizarro Episode: While comedic episodes are nothing unusual, this episode, in which the Doctor and Clara somehow manage to locate Robin Hood (even though the Doctor is certain he's a fictional character) and engage in comedic goings-on, feels out of place given its placement early in the Twelfth Doctor's first season. It doesn't help that Peter Capaldi plays the Doctor differently than he plays the character the rest of the season and the episode as a whole takes on the feeling of something that could easily be explained away as All Just a Dream, though it isn't.
- The Un-Twist: "Robin Hood" actually is the real deal. Only in a Trope Overdosed show like Doctor Who can this count as a plot twist.
