How did Abanks know that Avery was dead?
Seriously. This all takes place within a couple hours. Thats probably not enough time for the news to spread around the island. The only ones that would have a idea of his fate are himself (Avery), Abby, and the guys who did it. Abby probably had a feeling what was gonna happen, but wouldn't know specifics. The guys that did it obviously arent talking.
How did Abanks know that Mitch's "lawyer friend is dead, He drowned in the bathtub"
