There have already been hints that season two of Titans will adapt "The Judas Contract" and now Geoff Johns has confirmed that we're going to see Deathstroke (and his son, Jericho) in the DC Universe series down the line. "You’ll see Deathstroke in Titans eventually, but it’ll be a new version," the executive producer said, confirming it will be a new take. "You’ll definitely see it in the show."
In other words, neither Joe Manganiello nor Manu Bennet will end up suiting up as Slade Wilson in the series and this version will be differentiated somehow from what's come before which is no bad thing.
However, another character on the way to the series is Deathstroke son, Joe Wilson. Also known as Jericho, he made a brief appearance in Arrow and DC Co-Publisher Jim Lee confirmed that we'll see him in Titans too. "Last night at dinner, Geoff and I were talking about Jericho," he noted. "So yes, definitely." Perhaps we'll get some hints about both characters when season one debuts next week?
After all, a mention or cameo appearance from the villains would be a cool way to end the season...
