"Changelings" is the ninth episode of Season Six of ABC's Once Upon a Time. It was written by David H. Goodman & Brian Ridings, and directed by Mairzee Almas. It is the one-hundredth and twentieth episode of the series overall, and premiered on November 27, 2016.
In a Fairy Tale Land flashback, Rumple collects Jack and Jill's son as bait to lure a powerful being to him. Back in Storybrooke, Gold tells the Evil Queen that she must kill Zelena, and the EQ makes a decision that will change her relationship with her sister forever. When Belle discovers Gold’s plans for their son, she convinces Hook and Emma to help her steal squid ink that can immobilize him, and, as a result, Belle is left to make a sacrifice that will affect the lives of everyone in Storybrooke. Meanwhile, Jasmine finds a genie-less lamp that she hopes to use to save Agrabah, and Aladdin finds a way to be her hero.

- Granny serves Belle a cup of chamomile tea that "soothes the soul", and Hook comments on how it helps calm the nerves. Unbeknownst to Granny, however, the tea has been dosed with aging powder that accelerates Belle's pregnancy and causes her to go into labor.

- On the library shelf where Belle finds the Manual on Defeating the Dark One in her dream, there is a a bound volume of Scots Law Times from 1927. Scots Law Times is a Scottish law report service containing coverage from every Scottish court, a service which dates back as far as 1893.
- Mars and Venus, a famous painting by the Italian Renaissance painter Sandro Botticelli, can be glimpsed behind Mr. Gold as he is talking to Belle inside the convent. It can be seen more clearly in the Season Five episode "Our Decay".
- The essay written by one of Mary Margaret's students, Victoria N., is about "the best invention of all time". It reads:
was ever invented is swimming polls [sic]! Swimming
pools are the best inventions cuz you can dive
from high places, and there is a lifeguard [obscured]
dangerous as if you did it [obscured]
on Any Parte of the body.
Stand ye in front of a large looking glass.
Mix the ingredients together full well and apply
to the glass that reflects the portion of the body to

- The book that Mr. Gold is reading when Hook walks into his shop contains an illustration of a magic circle from Key of Solomon, an old grimoire incorrectly attributed to King Solomon. This particular illustration is from one of the earliest manuscript of the grimoire, entitled The Clavicle of Solomon, revealed by Ptolomy the Grecian, written in English and Latin and dated 1572. Note that the illustration has been touched up, colorized and modified by the prop makers: For example, the sensors in the north, east, south and west have been replaced with new symbols (a star and circle inside a circle), the Stars of David (✡) have been replaced with three five-pointed stars (☆), the text in the inner circle (which has no actual meaning) has been slightly modified and the two lowermost text passages have switched sides, while the word "Plemoma" (Esperanto for "people") has been added to the center.
- The illustration on the other side of the page (seen through the paper) contains symbols from the outer circle of the Pentacle of Solomon, an illustration found in the Lesser Key of Solomon, an anonymous grimoire on demonology compiled in the mid-17th century. (Note that since the page is seen from behind, all the symbols are mirror-inverted.)
- The sword Emma and Hook find has the same design as the swords used by the Knights of the Round Table in Season Five, albeit without the red jewel in the handle.
- According to Giles Matthey, he and Emilie de Ravin both played on the swingset between set ups.
- When Mr. Gold enters the convent, there is a glass-stained window in the hallway behind him. It is the same window that was added to the landing outside the entrance to the Blanchard Loft in "Broken".
- The dress worn by the Evil Queen at the power station is the same dress that Regina conjured up when under the influence of the Spell of Shattered Sight in "Shattered Sight", and when selecting a dress for the ball in Camelot in "The Price". Regina's real counterpart wore the same dress when giving the Count of Monte Cristo the Agrabahn Viper venom in "A Bitter Draught" and in Regina's dream in "Poor Unfortunate Soul".
- When the Evil Queen attacks Zelena, she is wearing the same outfit that Regina's real counterpart wore during battle in "The Cricket Game".
