Does Doctor Who Need The TARDIS To Regenerate? It’s Complicated

There’s long been a question over whether the Doctor needs the TARDIS to regenerate in Doctor Who, and the answer is complicated. Regeneration has been a core part of Doctor Who since 1966, but there’s still a lot that’s unknown about the process itself, and the role of the TARDIS is one such thing. The Timeless Child revelations complicated this core aspect further by revealing that, as an abandoned and mistreated child, the Doctor provided the genetic building blocks that allowed the Ancient Gallifreyans to unlock the secrets of regeneration.
