Titans (2016) #20

'Titans Apart' part one! After the Titans are forced into a hiatus by the Justice League, Roy Harper, a.k.a. Arsenal, finds himself without a team-but not without a purpose-as he investigates the rise of a dangerous new drug running rampant in the streets of New York City. But Arsenal isn't alone-his ex, Cheshire, has joined him on his mission! But are her motives as altruistic as she claims? Or are darker forces at work?
