* In keeping with next seasons found-family theme, a villainous cabal rather than a single foe will torment Oliver & Co. throughout the season. As reported here, Michael Emerson (Person of Interest) will be part of the group, and Anatoly will also return with a literal vengeance, executive producer Marc Guggenheim previewed. You can also expect a really cool announcement [about] Richard Dragon from the comics, who will also be among our villains.
* Oliver is not the best dad, Stephen Amell admitted. My first day on Season 6, it was all with Jack [Moore], who plays William. Although the two had shared scenes before, we had never really acted together, and I was really legitimately nervous. He exceeded my expectations, and Im loving my scenes with him. But yeah, hes a st dad.
* Season 6s occasional flashbacks will be character-specific. In addition to his appearance in the season opener, Manu Bennetts Slade is also coming back for a special two-part episode in the first half of the season, where were really going to be focusing hard on his character, post-everything hes experienced on the show, Guggenheim revealed. We intend to do a Slade Wilson flashback story.
* As for Vigilantes mysterious identity, you can probably expect that whoever is underneath that mask is a face that is familiar to you, Guggenheim teased.
* Kacey Rohl will reprise her role as Helix hacker Alena.
