Continuity

 * The Eleventh Doctor has not met Clara before, nor does he recognise her as her Victorian London splinter. (TV: The Snowmen)
 * The Doctors causing a paradox within a fixed point in time results in the appearance of the Reapers. (TV: Father's Day)
 * The Twelfth Doctor appears to be unable to remember Marinus. He has seemingly forgotten other details of past adventures before. (TV: Deep Breath)
 * Once again, Clara uses the TARDIS' telepathic circuits to pilot the ship while the Doctor is asleep. (TV: Listen) This time, however, she is able to pilot the TARDIS with pinpoint precision. She also speaks kindly to the TARDIS afterwards. (TV: Clara and the TARDIS)
