Hush keeps poppin' up (is that good?)

Gotham Knights writer A.J. Lieberman talks to Comic Book Resources about his continued focus on Hush, the new Bat-rogue introduced by writer Jeph Loeb and artist Jim Lee in their 12-part "Hush" storyline.

In 'Batman' #619, readers learned that Bruce Wayne's childhood friend Tommy Elliot was Hush. The mystery was solved. Or was it? In 'Batman: Gotham Knights' #60 writer A.J. Lieberman shocked readers by revealing that Hush has been keeping the real Tommy Elliot prisoner. CBR News spoke to Lieberman about his work on 'Gotham Knights' and the renewed mystery of Hush's identity.

What? I guess this is what I get for missing a few issues of GK. But I just couldn't stand the art. So, who could Hush be? I certainly hope they have someone in mind and are building a mystery around that, instead of just making the entire plot point a knee-jerk reaction to the obvious move that Tommy Elliot was. Then again, what do I know?
