Thea, last seen briefly in the Season 7 documentary, will recur in the final season.
Adrian Chase (Josh Segarra)
Segarra’s character killed himself at the end of Season 5, but showrunner Beth Schwartz teased that “Chase comes back in a different way than expected.” He can be seen in the Season 8 trailer.

Tommy Merlyn (Colin Donnell)
Tommy will be back in the premiere, as seen in the photo above, but we’ll have to wait and see just how that’s possible since he died in the Season 1 finale. Considering the other photos for the episode — and the title (“Starling City”) — it seems probable that this is the Tommy of another Earth.
But before that time comes, they'll also get to see some key characters returning in some capacity in the eighth and final season. And we already know one member of Oliver's (Stephen Amell) team will be back in a recurring role.
