WARNING: The following article contains spoilers for the Titans Season 1 finale, "Dick Grayson," streaming now on DC Universe.
For the first 10 episodes of its debut season, DC Universe's live-action Titans resisted the siren's call of the post-credits scene, which have become such an integral part of modern superhero movies. But with this week's finale, the series finally gives in, in a big way, setting up the addition of another hero in the second season. Or make that two heroes.
The episode takes place in a dreamscape created by Rachel's demonic father Trigon (Seamus Dever) to lead Dick Grayson (Brenton Thwaites), through his own choices, from an almost-idyllic life to a place of darkness. Although "Dick Grayson" seemingly confirms the existence of Superman in Titans' universe -- he and Bruce Wayne had a falling out, we're told -- and shows such Batman foes as The Joker, The Riddler, and the Ventriloquist and Scarface, all of that occurs in Trigon's imaginary world. The post-credits scene, on the other hand, is most definitely set in what passes for the real world on Titans.
That shattering of glass is accompanied on a black scene by the words "Somewhere in Metropolis." When the camera fades in, however, we're not greeted by the Man of Steel, but instead the interior of Cadmus Laboratories. For fans of the animated Young Justice, the meaning is immediately clear: Conner Kent, also known as Kon-El or, yes, Superboy.
A figure is seen passing by on a monitor, before walking into view in the lab, and away from the containment pod he only just escaped. A display flashes a warning that "Subject 13" is offline. That's an allusion to the character's comic book roots, in which Project Cadmus referred to Kon-El as "Experiment 13," because he was the 13th attempt by scientists to create a clone replacement for Superman following the hero's death at the hands of Doomsday. On Young Justice, Conner was discovered by Robin, Aqualad and Kid Flash, and liberated from Cadmus.
Titans' post-credits scene depicts Superboy leaving behind injured, and perhaps dead, Cadmus scientists and out a dog with glowing red eyes. That's of course Krypto, Superman's beloved pet dog -- or at least a version of him. Considering that he's kept in a glowing green cage by Cadmus, it's likely this incarnation is instead a laboratory experiment.
And just in case there were any doubt about the identity of the obscured figure -- really, how could there be? -- the camera helpfully focuses on the iconic "S" emblem tattooed on his bicep.
The introduction of both characters is obviously big for the second season of Titans, potentially giving the team powerhouse new allies in the fight against Trigon, or else two more obstacles. Either way, it changes the game dramatically.
Now streaming on DC Universe, Titans stars Brenton Thwaites as Dick Grayson, Anna Diop as Kory Anders, Teagan Croft as Rachel Roth and Ryan Potter as Garfield Logan, and guest starring Rachel Nichols as Angela, Seamus Dever as Trigon, Minka Kelly as Dawn Granger, Alan Ritchson as Hank Hall and Curran Walters as Jason Todd.
