The latest details and spoilers for "Arrow" Season 6 will feature a possible death of a Character during the plot of the first episode.

Death in the first episode

Executive producer Wendy Mericle teased the possibility of a character's death during the season 6 premiere of "Arrow." Mericle told ComicBook at San Diego Comic-Con that audiences will see Oliver Queen's reaction to that person's death and how this impacts him during the sixth season.

"I think you will see both, "Mericle said." We will get answers. You'll know by the end of the premiere who made and who didn't, and you'll see Oliver mourning."

The death of a character in "Arrow's" premiere was teased in the SDCC trailer as a clip from the season 5 finale shows the island of Lian Yu being blown up by Prometheus.

Team Arrow and William Clayton's mother, Samantha were caught in the explosion as Oliver and William looked on in shock and horror.

Unfortunately, Oliver will not be mourning for too long as he returns to Star City to meet a new foe for season 6, Richard Dragon. Mericle described Richard Dragon as being similar to Prometheus, who like to keep things personal when he deals with his enemies.

Co-producer Marc Guggenheim added that Richard would be a grounded and gritty crime lord, unlike the past main villains of the show like Malcolm Merlyn, Deathstroke and Ra's al' Ghul.

Exploring Black Siren's past

Another surprising twist for "Arrow" season 6 will be Black Siren's past as actress Katie Cassidy stated in an interview that her character would be more complicated in the show, especially when it comes to the subject of Oliver Queen.

"Yes, I think the more we learn about her backstory and what her relationship was like with Oliver, absolutely," Cassidy said. " I think it will make sense in the end and not necessarily make her as bad as a person."

Black Siren is the Earth 2 version of Laurel Lance, and she made her debut in the second season of "The Flash" as part of Hunter Zolomon/Zoom's metahuman army.

Unlike her Earth 1 doppelganger, Black Siren is a ruthless fighter who enjoys inflicting pain by the use of her sonic scream.

Laurel then joined Prometheus during the second haft of "Arrow" season 5 pretending to be Team Arrow's, Laurel and attacked them in their base. Black Siren's reason for joining the villain was for her freedom in the S.TA.R. Labs prison and as a way to torture Oliver emotionally, since their Laurel died in season 4.

"Arrow" season 6 will air on Thursday, Oct. 12 on the CW Network.
