During IGN’s Comic-Con 2018 live show, DC’s Geoff Johns discussed the plot of Titans, as well as why Robin said “F*** Batman” in its reveal trailer.
“That’s actually part of the story of Titans,” Johns explained. “This is after he’s obviously split from Batman if that wasn’t clear enough.” Johns continued by saying that why Robin left Batman and what happened between them is going to be explored in Titans.

“There’s a story to be told in the series. Dick Grayson is really trying to find a new place in the world — a new spot, a new life, just like all the other Titans are. They’re all lost, and they find one another to form this surrogate family.”
