Elsewhere[edit | edit source]

Missy and Clara explored a sewer beneath a Dalek city on Skaro. Missy explained to Clara that the sewers' primary function was not to house the Daleks' waste, but instead to house decomposing, used Dalek mutants. This was because Daleks were genetically engineered to not die naturally.
