Jeanne is not sealed, only prisoned. Cao Cao can ask for freeing his allies, since he contributed in fighting 666 and Qlippoth.

Neither Le Fay nor Bennia mention a thing about wanting to be in Ise's peerage or team. So i doubt it'll really happen. And personally i don't mind it too. If everyone Ise is close with joins his peerage then it would be nothing but boring. I would prefer is Le Fay stays with Vali Team and Bennia with Sona.
