Was this the planned finale, or was there one more episode that they couldn't film due to COVID? I'm thinking about the cartel leaders last words before he was dispatched. Something to the effect of "when the city is in flames, remember, I tried to stop it". It was mentioned briefly afterwards and then not again. I wonder if some bad event was supposed to happen which the cartel leader for whatever reason wanted to prevent, which is why he took the risky trip to the US. Maybe if there was supposed to be another episode, it would have been addressed later. Or if not, maybe something for next season.
