.....Boy am I coming late, sorry my body seems to have decided to take a week off with a very painful kidney/bladder/urinary infection. I won't get graphic, but sleep deprivation produces some awesome hallucinations trips.
Ned has given himself up, Shane was a bit right that he will use 'old' equipment' to re-fit, the next logic point is that he indeed has the old hulls off the Aries in the storage yard somewhere. The narrator states;
Trevor was getting ever closer to the truth, though he remained blissfully unaware of one critical fact; if he and Shane were ever to attain the secret that they were seeking, that knowledge would mark them for death via the entire cartel. At the moment, Bridget and the cartel sought to destroy the boat, and thus the tape with it. He and Shane were in danger mainly due to their proximity to it. However, if they viewed the tape, they would become the personal targets of one of the world’s largest and most ruthless criminal organizations – one with global reach.
So the only logical explanation is that Trevor and Shane never see or find the tape, that customs and Nate have found a 10 year old hull, given that the cartel has a plant in the Australian infrastructure. The finger will point to a lying Bridget and the fact that Trevor and Shane are innocent of any knowledge, thus the cartel needs not to deal with them.
That leaves Bridget in a problem, she has to flee and has nobody to have at her side as she prematurely killed Billy. Bridget is resourceful, but there are no characters left for her to lean on. There is no reason for her to go after Trevor anymore other then revenge, the only thing I can think of is that Julie resurfaces. Nice chapter CJ!
