They have a spell drawn over them together, they’re thrown in a heap, Qifrey lifts one, then???

Brimmed Hat mage put a portal spell on the paved stones to lure and trap the girls in the maze/pocket universe. -> After they stumble into the trap, the mage destroys the paved stones to close the portal and keep anyone else from finding them /helping them. -> the girls break the magic seal on the inside that keeps the spell active -> with the spell broken the door back to reality opens and Qifrey can enter and save the girls.
