Cool trailer. Didn't reveal too much but it looks like this season will be as kickass as Season 5 was.
While talking about flashbacks this season at Comic-Con, Marc Guggenheim also announced a Deathstroke focused two-parter:
Canon novel "Fatal Legacies" by Mark Guggenheim and James Tuck to bridge seasons 5 and 6. Available for pre-order in paperback. Description...
I don't see anything there definitively stating that the novel is canonical. The fact that it's co-written by Guggenheim suggests it might be, and the blurb is doing its best to give that impression, but it doesn't seem that previous novels or comics have been.
Well, Guggenheim's involvement and comments made in other articles suggested it, but I do know how such things work in the real world. He will abandon it in a heart-beat if the story needed him to.
I can't even be mad anymore. At this point, I'm legitimately convinced that the Arrowverse shows make heroes into villains for no reason specifically to give fans the middle finger. To be a full Arrowverse screw job though, they'll also need to reveal at some point that the character they've been calling Richard Dragon has actually been *random villain selection* the Aztek villain Piper all along
The trailers keep going to such great lengths to avoid confirming that anyone has survived beyond Ollie, his kid, Slade, Dinah, and Black Siren. Although the press releases still list all the team members from last season.
