The upcoming Titans may have flashbacks to Dick Grayson’s youth, which seem like they will include Batman as well.

The series, to be released on DC Comics’ own streaming service, will focus on a team of young adult superheroes. Brenton Thwaites (of The Giver and Pirates of the Caribbean: Dead Men Tell No Tales) will play Dick Grayson, the now-grown Robin, who based on the comics will presumably be the group’s leader.

Casting calls for the show have been released. While they use fake names to avoid spoilers, the description of “YOUNG JOHN CROSSLAND” is almost certainly meant to be a younger Dick Grayson, given the basic physical description and a note that he is “not afraid of heights.” (Dick grew up in a circus, training with his parents as a trapeze artist.) The role is listed as recurring, implying that there will be multiple flashbacks to Dick’s earlier days in the show.

Meanwhile, another recurring character listed, “Dave Story,” seems to be hinting at Bruce Wayne/Batman. It asks for a Caucasian male in his 30s-40s who is “polished” and “unwavering.” Specifically, it compares him to a young Jack Nicholson.

In most versions of the Titans origin, Dick started the team after fighting with his adoptive father and mentor. Though the two would eventually reconcile, it makes sense that any appearances by Batman in this series, at least early on, will be flashbacks, explaining how Dick became a superhero and what caused the Dynamic Duo’s falling out.

Alternatively, this character could be the Joker, who was played by Jack Nicholson in the 1989 movie. However, the rest of that description does not quite fit the Clown Prince of Crime as well as it does the Caped Crusader, making it likely a little joke.
