Blackthorne played Quentin Lance, the father of Canaries Sara and Laurel Lance, in Seasons 1 through 6 of Arrow. In the Season 6 finale, Quentin took a bullet for Laurel "Black Siren" Lance, the Earth-2 doppelganger of his beloved daughter, and received a life-threatening injury. Though it didn't kill him on the spot, he died later during surgery.

As such, Blackthorne's role in the upcoming final season remains a mystery. Considering multiple universes and time travel have been involved in Season 8 so far, both of these could factor into his return. If he is from another universe, he could play a new character or a different version of Quentin. If it's time travel, then he may be Quentin from an earlier point in the show's timeline.

Airing Tuesdays at 9 p.m. ET/PT on The CW, Arrow's final season stars Stephen Amell as Oliver Queen, David Ramsey as John Diggle, Rick Gonzalez as Wild Dog, Juliana Harkavy as Black Canary, Katie Cassidy as Black Siren, Katherine McNamara as Mia Smoak, Joseph David-Jones as Connor Hawke and Ben Lewis as William Clayton-Queen.
