I guess she can come in...alone and unarmed... She'll have to go through the metal detectors and security checkpoints, though... All of them. Should see her in here about the same time next year.
As far as I know, humans who are children of the mother's first marriage retain the biological father's family name why would it be different for Susie.
But in the Ben Egg clan, all semi-members are forced to take the name of Ben or Bena, anyhow.
Not that it matters in this case. Look what we found on "Susie" at one of the security checkpoints' metal detectors! *holds up a wire whisk* I doubt she's even a real egg...no egg could bring itself to TOUCH one of these weapons of mass destruction...
