Solid Ground (unproduced TV story)

✅ Solid Ground was a proposed Twelfth Doctor episode pitched by for Doctor Who in 2015. It involved a planet where the rulers had convinced the population to convert themselves into holograms to save the environment, but the Doctor discovers that the conversion process is imperfect and the rulers themselves have remained in their real bodies. The rulers try to stop him from releasing this information by revealing that the companion has been replaced with a hologram; when the Doctor finds her body and rescues her, her hologram version decides to keep living her life on the planet.

After the pitch was rejected, Slott adapted it into a Silver Surfer comic story, Worlds Apart.
