Well, they're not the "same person", isn't Helena the product of Batman and Catwoman and Damien the product of Batman and Talia al Ghul?
I like World's Finest as well but it does seem to "lack" some direction. I mean, where is the book going
Read "Dial H" last night as well as "Earth 2." Earth 2 I'm wavering on a bit as well as Dial H. But this issue of DH actually wasn't too bad and actually seems to be taking the story forward. One thing that is odd other than the occasional wink or nod in the art it seems disconnected from the rest of the DCU. Where IS Batman, Superman, Wonder Woman, etc. during all of this? It'd be nice to seen SOME reference to them.
