💨 Abstract

Ncuti Gatwa's Doctor Who character regenerated into Billie Piper, who originally played Rose Tyler. In the series finale, the Doctor fought two Ranis and an ancient beast, The Omega, to save reality. After saying goodbye to companion Belinda Chandra, the Doctor regenerated into Piper, who gave a brief smile and said, "oh, hello" as the credits rolled. The reasons for this unexpected regeneration remain unclear.
