Turn Left (in-universe)

In late 2020, a Doctor Who fan finished an episode of Doctor Who. The final scene ended when a bell was heard, and a female character asked the Doctor what was "Bad Wolf", and he responded by saying it was "the end of the universe". The episode then transitioned into the credits. (WC: U.N.I.T. On Call)
