We watch "The Zygon Inversion" (Series 9, Episode 8) where the Doctor and erstwhile companion Osgood make an early departure from their flight due to rabid Zygon anti-human-maskers. Whilst said 'peaceful' protestation is occurring, Clara attempts to isolate herself from... herself (?), Osgood brings Bonnie into her 'friend bubble', and the Doctor prevents the vocal minority from unboxing the 'big lie'. Wait a tic... wasn’t this broadcast in 2015? Then why does this feel so familiar? Hmm.
