Prometheus would know about the pit because Malcom told him. Malcom would work with Thawn and Darhk because he wants to change what happen'd to his wife. Like i stated the pit makes people go crazy, wich could be why he attacked Black Siren. Now i know it likely won't be Tommy but it would be a huge twist and it'd be pretty emotional for Oliver to find out his best friend is Prometheus.
