"Arrow" Season 5, episode 6 will introduce a new character named Konstantin Kovar (Dolph Lundgren).
According to TV Line, Konstantin is a Russian native who Oliver Queen (Stephen Amell) previously met. The lead character and his partner Taiana agreed that they will take him down.
Meanwhile, "So It Begins" will see Felicity (Emily Bett Rickards) and Curtis (Echo Kellum) realizing that Promethues' victims have ties to Oliver's past. The two characters will remain protective of their leader and friend especially since Felicity and Oliver just had their talk in episode 5.
In the teaser released by The CW for episode 6, Rag Man (Joe Dinicol) could be seen telling Oliver that Prometheus believes the lead character is the real serial killer. This will encourage Oliver to take down Prometheus as quickly as possible and with the help of his newly-formed team.
Elsewhere, Thea (Willa Holland) will develop a close friendship with Quentin Lance (Paul Blackthorne), who is still a mess following his daughter Laurel's (Katie Cassidy) death. In the previous episodes, Oliver assigned Quentin to become his deputy mayor so that he can look out for the residents of the Star City when Oliver is busy working as the Green Arrow.
In other news, Felicity will contemplate on telling Malone (Tyler Ritter) the truth about her work. Since Felicity and Malone have already started dating, the former knows that being truthful is the only way for their relationship to flourish. However, Felicity doesn't have any idea of Oliver will be supportive of her idea to tell Malone the truth about working with the Green Arrow.
Previously, Malone already crossed paths with Oliver as the Green Arrow when he lied about having an emergency and called him for help.
"Arrow" Season 5, episode 6 will air on The CW on Nov. 9 at 8 p.m. ET.
