This episode, and those that follow, establish that Series 1 of Class takes place in the fall of 2016, sometime after the death of Clara Oswald. However dialogue in "In the Forest of the Night" establishes that that episode also takes place in 2016, which was followed by "Last Christmas" which, for Clara, presumably takes place at Christmas 2016 at the earliest. That means at the very earliest Clara could have died (allowing time for the established long gap between the Christmas special and Series 9 and the events of the first 10 episodes) was sometime in 2017, which make Class Series 1's correct date closer to 2018, if not later. 23skidoo ☎  13:34, November 14, 2016 (UTC)
