This one is another lead-up to the fiftieth anniversary episode, “The Day of the Doctor.” Some of you may have already seen “The Day of the Doctor,” but we’re seeing it on the big screen tomorrow night. (Q didn’t want 3D IMAX, so we’re seeing a regular 2D showing.) Some of you may have already seen “The Last Day” as well, but since I’m avoiding news and spoilers, I’m not hearing about these things right away…
