Ncuti Gatwa's run as the Doctor in "Doctor Who" has concluded after just one season. In the series finale, his Doctor regenerates into Billie Piper, who previously played Rose Tyler. Piper's statement confirms her return but remains vague about her role. Gatwa's departure, following rumors and declining ratings, marks the second shortest tenure as the Doctor. The show's future beyond its current two-season order remains uncertain.
