I find this part of the story a little confusing because initially, blondie would also be Jason’s boss and TJ, Ian and Jamie were already under Jason by this point. But then Jason wanted to go on his own, like be the boss of his own gang, and TJ wanted to follow him. So he asked Jason to bring Ian with him, which is why Jason said Ian needed yo be clean for that. Hence the reason why TJ sent Ian to rehab, so by this point in time, they it’s either that TJ Is enacting the plan that allowed Jason to go on his own or did that already happen?
Sorry if that explanation was only more confusing

is david the drug dealer that gave the stuff to ian in the previous ep? and who’s the blondie, is he part of the gang? if so, is the dude with cancer in a higher position than blondie or has that not yet been revealed.. i would try to find it in the previous chaps but idk where to find them…
