* HilariousInHindsight: The canonical Tenth Doctor was also quite egotistical, and liked to lick things.
** He could also be easily described by his fans as "Cute, sexy and lick-the-mirror handsome".
** Richard E. Grant would later go on to play the reimagined Great Intelligence in Series 7, who functions as an EvilCounterpart to The Doctor.
* RetroactiveRecognition: The Tenth Doctor (Richard E. Grant) goes on to be the Doctor ''again'' for ''Scream of the Shalka'' (albeit as the Ninth), and was also in ''The Name of the Doctor'', where his character threw himself into the Doctor's time line.
* FridgeBrilliance: Although nobody ever actually follows up when they say "I'll explain later", circumstances usually lead to the answer. For instance, Emma asks the Doctor asks why the Daleks didn't kill them, why there's a chair prepared, and how Zektronic energy will allow them to take over the universe in a matter of minutes.
** The answer for the first one and the second are that the Daleks needed the Doctor there to help in case something went wrong, which it did. Their justification of keeping him alive and compliant is quite sound.
** Zektronic energy allows the Daleks to kill the Doctor and the Master in such a way that they can't regenerate or resurrect. Since the Doctor is their biggest obstacle, they have a lot of investment in this ability, which would allow them to steamroll Gallifrey and change the timeline so that they're unopposed.
