She, alongside fans and the paparazzi, attempt to chase him down into a alley after they spot him on the streets. she also manages to catch a glimpse of the turtles as they attempt to escape by using a Ninja Smoke Bomb as a distraction which fails and reports it on TV afterwards [which enrages Splinter who grounds his sons for being exposed]. She and her cameraman [who the Turtles and Muckman spot after defeating Bebop and Rocksteady] then search and investigate the warehouse nearby. Muckman the distracts her while the Turtles escape and debunks the rumors about them existing which she then reports afterwards.
