The drug store owner is a Time Lord, and Bradley's RX is his TARDIS.
Benny's apartment contains a Hellgate
In one of the promotional shots for Episode 7, a set door behind the characters in Benny's apartment has been left open. OR IS IT? Cleo is KGB
Cleo is Mossad
Cleo is a hitchhiking ghost
Tim is working for the USSR
Tim is aspiring to learn Russian, allegedly to read "Dostoevsky in the original". He then disappears from the narrative, while leaving Beth plenty of opportunity to get drunk in his apartment. The apartment is bugged, and this is how Borgov's bodyguards think they know she is a drunk. Beth is autistic
Beth has clear autistic traits, but most people seem to attribute that to her trauma and upbringing. However, I found there were various directorial choices made specifically to show that she isn't who she is as the result of trauma and upbringing, which in turn suggests that she has these traits because she is in-fact autistic. I think the reason for this directorial choice is to avoid unfortunate implications by implying that trauma is a prerequisite for genius.
