It's utterly incoherent narratively speaking. The whole initial set up scenario for the game was a fairly ordinary guy from a fairly ordinary lower middle/middle class family getting the hell out Dodge due to the "complicated" relationship he had with both his sisters, but returning due to his mother's "accident". That "accident" being the consequences of the criminal activities of a ne'er-do-well uncle was also a good set-up.
From that we went to everyone being either involved in or okay with criminal/gangland or skeevy activity, with absolutely no set up.
I honestly had to double check whether there was multiple writers for Oceanlab's games because compared to Summer's Gone (which also has plot/writing issues), or even the original version of this, the ridiculous tonal shifts and cringy dialogue here seem like the work of an edgy teenager.
