Plot hole: Lea has a criminal record, which includes theft. Lea told Casi, "You know how hard it is to live with a rap sheet hanging over you? How hard I had to hustle to even get a shit job at the tow pound?" Later, Casi made a reference to "most thieves" and Lea responded she's "not like most thieves." The tow pound is operated by the NYPD, so it is extremely unlikely that Lea would have been hired given her theft record, especially for a position that handles money/cash. (00:19:45 - 00:35:25)
Naked Singularity (2021)
1 plot hole - chronological order
Other mistake: A vehicle bought at a NYPD auction must be paid for in cash, including tax. Ballena won the auction with his $60,000 bid for the Navigator, but it did not appear that Ballena was carrying that amount of cash on him. (He was not carrying a bag or briefcase.) If Ballena did have the $60,000 plus tax in cash, it would have taken some time for it to be counted before the paperwork could be completed, but no money was shown during the process. (01:05:03)
Trivia: "Singularities" are infinitely dense points. When something is compressed to the point of having a volume of ZERO, its density is thought of as being infinite - in other words, a "singularity." A typical example is the inside (center) of a black hole. A huge star - that once had a large mass - was reduced to nothing, but that "nothing" has a density that is infinite. It is at a point of "no return" (an event horizon), so is not visible. BUT "naked singularities" could exist - and be visible.
