Hartley Sawyer has been fired for sexist, racist and homoohobic tweets from an inactivated Twitter account that resurfaced. Apparently after he was reportedly called out by costar Candace Patton, who plays Iris, for his past behavior, after being outted by Shai Jackson for his years-old tweets... or so I understand.
I assume they will announced he and Sue eloped and moved far, far away when the new season starts. Provided they don't recast.
The Vulcan Reporter spotted Javicia Leslie on the set of HBO Max's Titans. While highly unlikely there is a crossover, this could be a joint promotion for HBO Max.
