Do they mean Gideon? He seems to think he can become a Savior if he kills Emma and rescues the realm of the Black Fairy
Actually, I’m thinking it’ll be Beowulf. The episode “Ill-Boding Patterns” seems to involve the Beowulf story. The episode title is a reference to Beowulf’s sword, Hrunting, which is probably the same sword we saw Gideon use in the vision. One of the promos also showed what looked like an army getting ready for battle.
