And how do they know?!
As a Line of Duty fan, I watched the pre series trailer repeatedly, looking for clues. Only to find out there was an Easter egg hidden in the trailer...
So for weeks I’ve been not only watching the trailer looking —unsuccessfully— for a oval of chocolate wrapped in bright foil and bows, but also wondering what possible relevance chocolate could have to the show 
It was only when listening to a podcast earlier this week that I realised what was actually meant by the term Easter egg.
How do people know this stuff? My DD just looked at me like I was crazy when asking her if she knew - apparently everyone knew. Except me
