What happened to all the Dr. Who companions?
Approved answer
What happens to the companions of Doctor Who?
They often face death, transitioning to a different state of existence. Sadly, many companions have indeed passed on. For example, Adric, Bill Potts (in a way?), and Donna Noble (not quite dead, though?). Rose Tyler died, but her copy survives in a parallel universe. Meanwhile, Clara is on the brink of death. This raises the question: What becomes of the Doctor?
