* AlternateSelf: This isn't the first time ''Doctor Who'' has included Arthurian mythology, but while there have been some claims that King Arthur was a real person in the Whoniverse a common explanation instead is that the myths take place in [[Recap/DoctorWhoS26E1Battlefield an alternate universe]]. This reveals that the legends also took place in the AlternateTimeline shown in ''[[Recap/DoctorWhoS31E13TheBigBang The Big Bang]]'' but are separate from previous depictions, since in ''Battlefield'' it was claimed that Merlin was a future version of the Doctor while here he is a separate character. A 2021 book named ''Legends of Camelot'' which features the Tenth Doctor and Donna arriving in another alternate universe with King Arthur [[CanonWelding provides the explanation]] that Arthur and Morgan le Fey are avatars of cosmic entities constantly battling each with the latter resetting time whenever Arthur gets close to winning, explaining the different interpretations of the legends, while the Merlin entity eventually trapped the others in a prison along with himself while making them both dream their battles are still carrying on. However cracks in the prison meant they still influenced several universes with their own versions of Arthur and le Fey, while Merlin had his own avatars such as the Doctor who play their role in stopping the entities from escaping.

* OutsideContextProblem: Merlin is this for Rory as he is actually shown to have magic powers, and while ''Doctor Who'' has always hand waved magic as being the result of advanced science or technology Rory lacks this knowledge. Rory himself is this for Malthus who finds his credibility challenged by Rory, a 21st century nurse who obviously would have more medical knowledge than a physician from the 5th/6th century.
