A subplot emerged around the character development of Elliot's childhood friend and love interest Angela Moss where she evolved from a brow-beaten assistant at cybersecurity firm Allsafe into a powerbroker at Evil Corp through first leading a massive lawsuit against them.
During an early point of this subplot, Angela Moss is blackmailed by The Dark Army into installing spyware (surveillance malware) into an Allsafe computer (the cybersecurity firm responsible for protecting Evil Corp).
The result of her action in this subplot ended up affecting the main plot when F-society was ready to initiate the hack against Evil Corp.
The Dark Army decided to back out from participating in the hack because of information they learned as a result of Angela Moss installing the spyware.
Without The Dark Army's support, F-society was unable to initiate the hack and had to realign their strategy, thus introducing a new obstacle in the main plot that had to be overcome.
