At the end of S1 + beginning of S2, Jimmy walks away from that cushy Davis & Main job, because he would rather do things the way he tends to do them: the Slippin' Jimmy way. Kim desperately tries to convince him to take the job, and in response, Jimmy demonstrates to Kim the joy of running a good scam. This is, quite notably, the first instance of the Zafiro Añejo stopper as narrative symbolism.
Now, the situation has been reversed: this time, it's Jimmy encouraging Kim to follow the right path, and Kim refusing this, because she'd rather do things the Slippin' Kimmy way. A Zafiro Añejo stopper is once again present (and careful, it's sharp!), but Jimmy is forced to leave it behind, so he can live to fight another day.
...But Kim still has her stopper.
And for the second time, Cliff Main finds himself providing the wrong person with a solid job opportunity.
Wonderful how they've managed to wrap back around, and bring everything full circle. This show is brilliant. I cannot wait for the midseason finale.
