In the series 12 episode ‘Fugitive of the Judoon’ in response to someone (not going to say who!) saying something along the lines of ‘Well done, 5 points!’ the 13th Doctor says, ‘Don’t do points, points are my thing’.
My question is, are points her thing? I don’t remember a time when she references points in any previous episode. I haven’t watched the classic seasons of Doctor Who, so is this a reference to an older doctor?
Many thanks.
