I love how, despite the 20 year gap & several missing episodes between Hartnell and the 5 doctors they still remembered to have Hurndalls first doctor dismiss Tegan when she called him Doc, and they even revived the doctors dislike of the term for the 6th doctor. Very clever continuity
I’ve also never noticed the discontinuity where 11 shows a 1st doctor library card from when he lived at totters lane with “John smith” on it despite the fact that Jamie made up the Alias for 2. (Also does that short scene mean that the doctor has had his ID/the psychic paper on him the entire time and he never used it until his 9th incarnation?)
At 20:51, it’s funny to think that the antiques seller misheard the Daleks when they called him “The Doctor from Gallifrey,” and just figured he was called Galloway lol
