In Volume 22 it was quite clear that only Ise knew about what's happening inside the barrier, not even Rias, Grayfia or Zeoticus was summoned there to talk with their own family member. What makes you think the kids would be allowed to find out such highly classified info when people directly linked to the incident isn't.
