The title for the Season 6 premiere of Arrow, "Fallout," has been confirmed, just as production for Season 6 begins. Executive producer Mark Guggenheim posted a picture of the script on Twitter, which also reveals that the episode will be directed by James Banford and written by Guggenheim and Wendy Mericle.
The title seems to be a reference to the cliffhanger ending of the Season 5 finale, "Lian Yu," which showed Prometheus commit suicide while triggering a massive explosion on the island where Oliver's friends were located. Since it's less than likely that the show will kill off most of its cast at once, we're lead to believe that many of the characters will find a way to survive the explosion. However, even if everyone survives, we can still expect that the impact of the event will be huge. Guggenheim said in June that what happened on Lian Yu would lead to "other consequences."
Those "other consequences" are expected to be explored in the premiere. Oliver and his friends will have to deal with the result of the battle with Prometheus. The explosion could give characters both physical and emotional scars that they will need to overcome over the course of the next several episodes, perhaps even the entire season.

Not much has been revealed about the plot of Season 6, though Stephen Amell has said that the theme of the season is family. The identity of the main villain has also been kept under wraps. However, it has been hinted that hactivist group Helix could return as potential enemies for Oliver and his crew.
We also know that the season will be different from previous seasons at least in terms of the flashback portions of the show. Most flashbacks have dealt with Oliver's five-year absence following the wreck of his father's boat. Since each season featured flashbacks from a different idea, it was known for a while that Season 6 would have to either move on from the flashbacks altogether or find a way to incorporate them into the story.
The new season will have Katie Cassidy returning as a regular, but not as Laurel Lance, who died in Season 4 at the hands of Damien Darhk. Instead, the actress will play her Earth-2 doppelganger, Black Siren, who first appeared in Season 2 of The Flash and became a recurring foe in Season 5 of Arrow. She was on the island at the time of the explosion. Rick Gonzalez (Rene Ramirez/Wild Dog) and Juliana Harkavay (Dinah Drake/Black Canary) have also been promoted to series regulars.
For the new season, Arrow will move to Thursdays at 9 P.M. and will premiere on October 12.
