I've always absolutely loved this show and season 6 is not disappointing so far! As always, the plot continues to be fresh and unpredictable, and there is tension at every turn!
As for the Ryan Pilkington storyline - I've been waiting to see how this pans out for a while now. So far, you'd be forgiven for thinking he's just a run of the mill baddy - but if past seasons are anything to go by, we know things aren't always as they seem...
One of the ways the OCG have acquired 'bent coppers' in the past is by both grooming them from a young age (like Dot AKA 'The Caddy') and/or having them over a barrel - just as they did with Gates in season 1. Perhaps they've had something on young Ryan for some time now? Gates' story in season 1 certainly demonstrated the lengths people will go to in order to protect themselves and/or their loved ones.
Anyone who remembers that season will recall how un-phased Ryan's Mother was by his activities. We can be forgiven for assuming that was just because she was a terrible parent, but perhaps it wasn't that she didn't care about his involvement with the OCG, but rather that she relied on it to keep her family safe? Perhaps she got into terrible debt with them, and they threatened to hurt her and her son unless Ryan went to work for them? Maybe Ryan has been doing so for the best part of a decade with the constant threat of his Mother being harmed hanging over his head? Regardless of that, all I'll say is this - when the time inevitably comes for Ryan to go in for questioning with AC-12 with his Reg-15 and his tail between his legs, he will, as Hastings would put it, certainly have a tale or two to tell.
Could Ryan Pilkington be the secret key that AC-12 have been waiting for all these years? The key that will unlock this decade long investigation into collusion between the OCG and high ranking police officers, corruption, and maybe even the final piece of the puzzle... The identity of 'H'?!
