“Russian Doll” star Charlie Barnett has joined the final season of “Arrow” as John Diggle, Jr. — the other son of John Diggle.

The CW superhero series announced Barnett’s casting during the show’s farewell Comic-Con panel on Saturday, giving this description for the character, who joins following last season’s introduction of next-gen vigilantes Mia Smoak (Katherine McNamara) and Connor Hawke (Joseph David-Jones):

Diggle, Jr. — known as J.J. — is the Flashpoint-born son of John Diggle (played by David Ramsey) and Lyla Michaels (played by Audrey Marie Anderson). We meet J.J. in the future as the leader of the Deathstroke Gang, where he faces off against Mia and his adopted brother, Connor.

On top of the Diggle family drama, The CW warns that “with the reappearance of The Monitor (LaMonica Garrett) in the season seven finale of ‘Arrow,’ there’s no doubt that Oliver Queen (Stephen Amell) and Team Arrow will be facing a ‘crisis’ unlike anything they’ve previously faced before. “

Barnett joins previously announced new series regulars McNamara, David-Jones and Ben Lewis as Oliver Queen’s adopted son, William Clayton, respectively.

Aside from “Russian Doll,” Barnett’s other credits include “Tales of the City,” “Chicago Fire,” “Secrets and Lies” and “Valor.”
