In Season 5, the lives of the "Arrow" team have spiraled out of control after the loss of Laurel (Katie Cassidy). Oliver (Stephen Amell) is encouraged by Felicity (Emily Bett Rickards) to find a new team after Diggle (David Ramsey) rejoins the Army and Thea (Willa Holland) refuses to work with him. With Thea running the Mayor's Office alone as Oliver has his focus elsewhere, she appoints Quentin (Paul Blackthorne) deputy mayor. As the powerful Prometheus targets the Green Arrow, Oliver relents and brings Rene "Wild Dog" Ramirez (Rick Gonzalez), Evelyn Sharp (Madison McLaughlin), Rory "Ragman" Regan (Joe Dinicol) and Curtis (Echo Kellum) into the fold. The new team struggles with trust issues, but with a final addition of Tina Boland (Juliana Harkavy) they find their momentum and focus on bringing down Prometheus before he can destroy both the Green Arrow and Oliver. Episode 8 is part of the crossover event with sister shows "Supergirl," "Flash" and "Legends of Tomorrow."
