EW writer Natalie Abrams shared the casting news that she learned exclusively. With the episode set to air sometime in 2018, Abrams writes that Hudson will play Darryl, "a hardworking school principal for a school where students are deeply troubled by gang violence."
She adds that he is terribly frustrated over the fact that he can't do anything to stop the violence, and ultimately goes to extreme measures in hopes of making a difference.
Abrams adds, "I hear he decides to confront the kids 'in the language they understand best.' Make of that what you will."
Of course, this means that fans are left to guess now what Frank Reagan and his officers have to do with school affairs.
