We watch “The Name of the Doctor” (Series 7, Episode 13) where we finally discover the answer to that age old question: Why is Clara the Impossible Girl? Whilst said answering is occurring, the Doctor and Clara get an assist from the Paternoster Gang who show them this season’s big bad was inside them this whole time. We then revisit archival footage of (selected) past Doctors ‘green screened’ with a ret-conned Clara who saves the day and introduces us to a previously unseen incarnation of the Doctor. The only time that will ever happen for sure. Wait… what?
