I just thought of a question for those who have still been reading Red Hood and the Outlaws. Has the book mentioned where Sasha is? For those who don't know, she was introduced in Batman and Robin and is Jason's sidekick, named Scarlet. She was deformed by Professor Pyg and Damian attempted a botched save of her which kind of led to her deformity. The last we see of her before Red Hood and the Outlaw starts is that she chooses to remain with Jason at the end of the arc which is collected in the Dark Knight, White Knight trade. I'm assuming that at some point prior to the start of the Red Hood and the Outlaws that Jason dropped Sasha off somewhere. Deciding it was perhaps too dangerous for her to be his sidekick. Unless of course this has indeed been addressed in the book.
