Last week on Arrow, Lance (Paul Blackthorne) really came through for Rene (Rick Gonzalez), by arranging a visit with his daughter, and inspiring him to fight for her. Alena (Kacey Rohl) told Felicity (Emily Bett Rickards) that A.R.G.U.S. is holding their leader, Cayden James, without due process. He invented a biomarker tracker that they could use to get Chase (Josh Segarra), but wanted Felicity’s help at breaking him out. This put Felicity at odds with the team, and Diggle (David Ramsey) at odds with Lyla (Audrey Marie Anderson). Felicity was successful and she tracked Chase to their bunker. Cue explosion.
