"The Snow Queen" is the seventh episode of the fourth season of the American fantasy drama series Once Upon a Time, which aired on November 9, 2014.
Stunned by Ingrid's powers, the sisters decide to keep it a secret and place the ribbons from the kite on their wrists, vowing to be there and protect each other.
Ingrid decides not to join her sisters but takes a brief moment to look before returning to her room after her loneliness causes it to snow inside.
Later, Gerda goes to the Grand Pabbie and asks him to make a potion that will cause the residents of Arendelle to forget Ingrid and Helga ever existed in order to protect the future of the kingdom.
Emma then takes her in for questioning at the station, where, as expected, Ingrid is using the arrest to play mind games with her foster daughter.
After Elsa and Hook are unable to find Emma, Mary Margret blames herself, stating that no one wants their family to see them as a monster.
Finally, Gold receives a visit from The Snow Queen, who is ready to make a deal with him, as she has now figured out what his plan is.
Then, Mr. Gold says that he will obtain the final ingredient with great pleasure, causing the Snow Queen to stare at him with a shocked expression.
In a review from Entertainment Weekly, Hilary Busis notes that "Tonight's Once is an exploration of control—and more specifically, what happens when people lose it.
"[3] Amy Ratcliffe of IGN rated the episode 7.9 out of 10, saying "The backstories of Once Upon a Time's villains don't always fit, but the Snow Queen's past was heartbreaking and matches the person she's become.
The plot in the present wasn't as solid as the flashbacks, but it did introduce a potential turning point for Emma and that character could use more development.
