She was kinda present, but no one was doing anything with her (other than having her in charge of LexCorp while Lex was president--which Rucka also did, I believe). But this . . .

It would be more believable to have her using her position as head of LexCorp to try to usurp her father's position!
Aaron "The Mad Whitaker" Bourque; and I say that fully knowing where Talia was before she got the LexCorp job.
