Something that`s been on my mind and can`t put the pieces together so putting them here
Cottan (1no. Caddy) from season 1 worked directly for Gates unit who was being used by the OCG.
Tommy (OCG) gets put in witness protection.
Akers (Police) is in witness protection unit has secret talks with Cottan that gets Lindsey Denton to help with getting him killed.
Akers dies.
Denton dies before exposing Cottan.
Cottan dies
Akers AC-9 (witness protection unit)
Cottan AC-9 (witness protection unit)
Jamie Beresford joins AC12 ( in my opinion as a replacement mole now Cottan is dead). Doesn`t get on in AC12 and transfers to......AC-9 (witness protection unit)
Hilton (formerly worked for an AC unit before moving to Central Police (my opinion witness protection) now has no mole inside AC12 so he blackmails Maneet (because her cousin was working for OCG at Eastside depot robbery). Once his affiliation with the OCG is discovered he`s killed off.
Only 2 people have survived the OCG at the moment who aren`t in jail
Biggeloe and Terry, who I reckon are both going to turn up dead this season
Sorry for the ramblings of what must look like a mad man
