A (Diabetic) Spy Among Friends…and a glaring error…

I’ve been gripped by the recent Cold War TV drama ‘A Spy Among Friends’ based on Ben MacIntyre’s book, but having spent the past few years immersed in writing about insulin and diabetes, I think I may have spotted glaring error in the portrayal of the condition in the TV dramatisation. In Episode 1, when MI6 officer Nicholas Elliott (played by Damian Lewis) suffers what appeared to be an attack of hypoglycaemia due to having diabetes, why did he suddenly break off from an intelligence debrief, to stagger out into the corridor, collapse against the wall and inject himself with a hypodermic syringe that I presume was meant to contain insulin??? This would have sent his already low blood sugars plunging even lower to dangerous levels!!?? A guaranteed way to put himself into a coma – or worse! Surely he would have known to grab a handful of sugar lumps from the tea he was sharing with Anna Maxwell-Davies and scoff them??? But I guess that’s maybe not as visually dramatic as a plunging a hypodermic needle into oneself?
