Lieberman brought Hush back to Gotham City with his first arc on "Batman: Gotham Knights." "In trying to keep the readers interested we wanted to really play with their expectations and what they might have thought was going on," Lieberman told CBR News. "I wanted to hook readers in with our first arc ('Pushback' #50-55) and then pull the carpet out from under them just as they were getting comfortable. Ideally this issue (#60) would've come right after 'Pushback,' but it was pushed due to the 'War Games' crossover."
Readers have been responding to the revelation of Hush's identity. "From the response I've gotten so far, it still seems to have registered," said Lieberman. "Anyway, as far as I'm concerned, once readers think they know what's going on with a character, it means one thing: boredom. Dropped in like this, it creates a new sense energy for the book and the character."
Along with Hush, Lieberman reintroduced another villain with a grudge against Batman, Prometheus, who single handedly took out most of the JLA in his first encounter with them. "When I discussed the initial arc with Matt Idelson and Nachie Castro ('Gotham Knight's editor & assistant editor) I wanted Hush to have almost like a body guard, someone to watch his back for him," Lieberman said. "They suggested Prometheus."
The relationship between Hush and Prometheus was never great to begin with and begins to deteriorate in upcoming issues of "Gotham Knights." "Obviously Prometheus is not without his own powers, but he is without his portal 'hammer.' Without the hammer, a big crutch both physically and mentally, Prometheus is at a disadvantage. Of course this is why Hush decided he'd be a good underling. In the up coming arc ('Human Nature' #61 - 65) Prometheus' relationship with Hush gets more precarious. And while Hush will be dealt a devastating personal blow, that missing hammer will force Hush to, literally put a gun to his head, to save a life he doesn't want to save."
Poison Ivy has appeared often in Lieberman's "Gotham Knights" run. At the end of Lieberman's first arc Ivy helped the Riddler escape Hush's wrath and she assisted Batman in finding Hush's hideout in issue 60. Lieberman said that both of these favors would come back to haunt Ivy during the "Human Nature" story arc.
Once "Human Nature," which highlights Poison Ivy, ends there will be two single-issue stories. Lieberman told CBR these issues, "Play off events that have come earlier, but are now seen from a different point of view than the first time they happened."
Readers looking for a quick resolution to the mystery of Hush should relax and enjoy the mystery as it unfolds. "Seriously, I think the fun in Hush is not knowing (for now). The more developed a character becomes, the more intense this mystery is."
