It's only a working suspicion, based on Gaiman's proven love for Lost Girls/Daughters/Princesses... She's not talking like Talia would, and her silouhette resembles a maxi-dress Helena wore several times in her old appearances, she seemed particularly snippish and trying to get him to listen during Selina's tale, and as for Talia's absence well... I'm listing her at the top of my DIES IN THE BTFTC SHENANIGANS list, based on that and several other factors. *And Bruce/Selina obsessive or not, I'm quite fond of Miss Al Ghul, Dark Lana Lang of the Batbooks that she is, so I may be a little sorrowful about that...
