Why did Elroy kill his mom?
In the present, Elroy confesses to Mariana that he did not kill Sara and that he wasn’t able to go through with their plan. From her reaction, it’s unclear why she was sleeping with Cesar and what the mother was hiding with Elroy. Definitely a weak ending. They had too many twists and turns when they should have tried to make sense of things more before this crazy jump at the end.
