So, everything that goes on in the A plot is peak Chibnall and if I don’t think about the direction this arc is headed, the Fugitive Doctor is an effective reveal and greater still are the scenes where the two Doctors just get to play off each other. The B plot has aged insanely poorly, both because of the allegations and because of hindsight. The entire thing is worthless, it adds nothing to the plot and is purely nostalgia bait and directly tell the audience what is gonna happen in the finale. Stupid. Relegates Graham, and in the second half, Ryan and Yaz, to the bench this adventure.
