Future episodes of Titans may take the action back to the past to further develop the eponymous team's backstory, focusing on a fallen team member.
DC Universe has released the episode titles for the fourth, fifth and sixth installments of Season 2 as "Aqualad," "Deathstroke" and "Conner," respectively. It had previously been insinuated by Donna Troy that the original lineup of the Titans had suffered a tragic loss involving Aqualad, and the fourth episode could be largely set in the past to examine what had befallen the Titans of yesterday.
Similarly, Deathstroke is hinted to have a secret past with the Titans, emerging from retirement after learning that the team had become active once again and relocated to San Francisco. The fifth episode may shed some light on that shared history, as well as Slade's connection to the recently recruited Rose Wilson.
Finally, Conner is the civilian alter ego of Superboy, first revealed in the Season 1 finale breaking out of Cadmus Labs with his trusty canine companion Krypto. Superboy has been expected to join the team since that cliffhanger ending and may finally join ranks to help the Titans against Deathstroke during the season's halfway point.
Streaming now on DC Universe, Titans Season 2 stars Brenton Thwaites as Dick Grayson, Anna Diop as Kory Anders, Teagan Croft as Rachel Roth, Ryan Potter as Garfield Logan, Curran Walters as Jason Todd and Conor Leslie as Donna Troy, with Minka Kelly as Dawn Granger, Alan Ritchson as Hank Hall, Joshua Orpin as Superboy, Chelsea Zhang as Rose Wilson, Chella Man as Jericho, Drew Van Acker as Aqualad, Esai Morales as Deathstroke and Iain Glen as Bruce Wayne.
