When Demetri is looking at Ian Rutherford's case it shows his nationality as Scottish. This would not be the case - it would instead say "British".
When Ian Rutherford's passport is found at the Blue Hand club, his nationality is listed as "Scottish". In fact, a passport would read "British Citizen".
When "quantum physicist genius" Simon (Dominic Monaghan) tries to use the Schrödinger's Cat thought experiment to explain quantum superposition to Camille (Ashley Jones), he makes errors which negate its explanatory power. For instance, instead of a being enclosed in a sealed box shielded against environmentally induced quantum decoherence, he has her imagine a kitten enclosed in her hand; and instead of an unpredictable quantum event (radioactive decay) being escalated into a macroscopic cat poisoning event, he has her imagining the kitten choosing whether or not to eat a poisoned sardine. Having made a nonsense of Schrödinger's elegant thought experiment by dumbing down, Simon nonetheless succeeds in seducing Camille.
Demetri finds the first members of the Blue Hands Club, he shows the camera Ian Rutherford's passport which clearly states he was born in Dec 1985 - later in episode 1.7 the MI6 Agent Fiona Banks states Rutherford was born in 1984.
