"Ill-Boding Patterns" is the thirteenth episode of the sixth season of the American fantasy drama series Once Upon a Time, which aired on March 19, 2017.
Beowulf then displays the sword, Hrunting, that Emma will take possession of in the future and leads his men into battle.
At Granny's, Archie finds Hook drinking, now that he realized that he killed Robert, who happens to be Emma's grandfather; however, he decides not to divulge details.
At the Clock Tower, Gideon comes to and is tied up, with the magic-draining cuff on, as Gold tells him about what happened during the first Ogre Wars when he attempted to stop it.
Gideon soon catches on to Gold's plan to erase his memory after he was given a tea that was laced with the forgetting potion, but his time with the Black Fairy has shown him how to counter it, and during a hug, he takes the dagger to control his father.
However, when Robin attempts to use the anti-magic potion, it fails to break the protection spell, and instead, the barrier blasts him backwards.
Knowing that he is stuck in Storybrooke, Regina, now convinced that the Wish Realm Robin will never live up to the one she remembers, offers to help him leave if he wants to do so.
Unfortunately, the "serum" Evil Queen (still in her form as a cobra) doesn't stay missing for long, because afterward, Robin is bitten by the aforementioned creature, and it turns out that the anti-magic potion really works, since the spilled anti-magic potion on Robin's hand restores The Evil Queen to her normal form.
