Video of the Day-Doctor Who-The Trial of a Timelord, 1986
The Doctor denounces the Time Lords as decadent and corrupt. The Master, present at the trial via the Matrix viewer, alleges that the High Council took advantage of the Doctor's blundering into the situation on Ravolox by making an arrangement with a future version of the Doctor - the Valeyard - to falsify evidence against the Doctor in return for his remaining regenerations. The Master claims that the Valeyard is the distillation of the Doctor's darker side, from between the Doctor's twelfth and final incarnations. The Doctor's demand that the trial be halted, since the same person cannot be both prosecutor and defendant, is turned down by the Inquisitor - but at that moment the Valeyard flees the courtroom. The Doctor and Glitz pursue him into the Matrix, a virtual reality where normal logic does not apply.
