There are only two episodes left before “Arrow” season 5 comes to an end, and next week’s episode will feature the return of Black Siren who will be teaming up with Adrian Chase. Team Arrow will be trying to organize a birthday party for Oliver Queen, but judging from the preview, it doesn’t look like it’s going to go so well.
“BLACK SIREN RETURNS – Black Siren (guest star Katie Cassidy) returns to help Chase (Josh Segarra). Felicity (Emily Bett Rickards) organizes a birthday party for Oliver (Stephen Amell) while Lance (Paul Blackthorne) is furious after Rene (Rick Gonzalez) misses the custody hearing for his daughter. Mairzee Almas directed the episode written by Speed Weed & Oscar Balderrama (#522). Original airdate 5/17/2017.”
