A reader asked why Persephone didn’t teleport away from danger during Daughter of Earth and Sky.
Without getting into spoilerific details, 90% of the time Persephone was in danger, someone had a firm grip on her. She can’t teleport in the living realm with anyone born outside Demeter’s realm and she can’t teleport with anyone in the Underworld that doesn’t read as a native. As for the other 10…
With the Reapers it wouldn’t have done any good. The have rights to teleport in both realms, so they would have just gone with her, and then what? She couldn’t explain what was going on to Hades, and if she stuck to the living realm, they’d already shown a willingness to retaliate with random humans.
With that last thing that happened, there was a shield in place to prevent teleportation, which is also why Hades could not interfere.
