Peacemaker has been flitting back and forth between the DCU and another dimension all season long. It was revealed at the climax of last week's episode, however, that the other dimension is Earth X – a reality where the Nazis won World War 2.
Emilia Harcourt immediately clocks that something is up with this version of reality, but Peacemaker is much slower on the uptake – at the start of episode 7, 'Like a Keith in the Night,' Harcourt has to point out to him that there are copies of Mein Kampf on every table and a gigantic Hitler mural on the wall!
