"Snow Drifts" is the twenty-first episode of Season Three of ABC's Once Upon a Time. It was written by David H. Goodman & Robert Hull and directed by Ron Underwood. It is sixty-fifth episode of the series overall, and premiered on May 11, 2014.
This episode is the first part of the season three finale.
While Mary Margaret and David celebrate the naming of their son at a coronation in Granny's Diner, Emma and Hook are pulled into Zelena's time portal and find themselves in the Enchanted Forest of the past. But in their quest to discover a way back, they must be careful not to change ANYTHING or risk altering the lives of their friends and family—as well as their very own existence.
In the past (our world) a young girl leaves with a couple in a car from an adoption agency, where a young Emma Swan is standing, looking upset that she'll never have a perfect family, but the foster manager comes up to her and tells Emma, "Don't worry, you'll find a home too, Emma."
In the present day, Emma looks happy and sees Mary Margaret holding her baby boy as she prepares for the upcoming coronation even though they haven't named him yet. Henry is looking for apartments and both Henry and Mary Margaret ask Emma what she thinks. Emma changes the subject and starts thinking why her parents are trying to expand the time they need to name the unnamed baby by using an age-old tradition. Meanwhile, Regina and Robin Hood are sharing some romantic time together. She tells him about how Tinker Bell told her about them being soulmates, how she saw the lion tattoo but didn't approach him in the pub. However, Robin is happy to hear that, saying it must be the right time for them now. Later on at Granny's, everyone is recalling or retelling stories of how Mary Margaret and David originally met back in the Enchanted Forest and how they kept running into one another and were destined to be together. When Emma reveals her desire to return to New York City with Henry in an attempt to leave Storybrooke behind, Regina and the others exclaim in protest. Suddenly Gold notices an orange beam rising in the distance, which he tells them is the time portal. As this starts to happen, Emma tells everyone that she wants to go back to New York City and everyone including Regina doesn't like the idea. Emma then walks out and Hook follows her, taking the fairytale book with him. Meanwhile, Regina, David, Belle, Gold, Robin, and Mary Margaret visit the jail to see if Zelena had died around the same time as the portal's opening. They see on the jail's surveillance video that she committed suicide, but are unaware that Gold altered the video to make it look like she killed herself.
As they stop by the park, Emma tells Hook that she is confused about going back to New York City. Hook then hands Emma the book, telling her Henry hoped it would remind her where they're from. The conversation is cut short when they notice the time-travel orange beam forming and Emma runs towards the barn, where the doors burst open. The beam pulls Emma towards the vortex, and Hook tries to hold her back by digging his hook into the ground with Emma holding onto his leg. Emma can't hold on and is immediately sucked into the portal. Hook says "One of these days I'm going to have to stop chasing this woman," and jumps in after her. The portal closes as her cellphone, which is left behind in the barnyard, is ringing with a call from David, who was trying to warn her.
Seconds later, both Emma and Hook land in the Enchanted Forest. It turns out that, while going through the portal, Emma was thinking of her parents' first meeting, which is how and where they ended up. The two then come across the wanted signs for Snow White from the past and then stumble onto a village, where they see Regina terrorizing the villagers demanding that they tell her where her stepdaughter is. Regina proves that she is not kidding by having a woman arrested for helping Snow. Emma wants to help the woman, but Hook warns her about changing the future so they can't save the woman, since the villagers that were threatened by the Evil Queen included Pinocchio, Geppetto, and Granny. Around the same time, both Prince Charming and Abigail are in the carriage in the moments before Snow and Charming are due to meet. Snow cuts a tree down to make her highway robbery, causing the carriage to stop as she is in a tree waiting. As Charming gets out the carriage to investigate, Emma makes the biggest mistake in altering the timeline by making an accidental noise and surprises Snow, who falls and runs away, empty handed without taking the jewels from the carriage, and preventing her parents from meeting for the first time. Emma discovers that she interfered the past and realizes that the only way to stop this altered timeline is by seeking out the only person capable of correcting this mistake, namely Rumplestiltskin. As the approach Rumplestiltskin's castle, Rumplestiltskin himself appears out of nowhere ready to kill Hook (as he still holds a grudge after Hook stole his wife, Milah, and took the magic bean Rumplestiltskin was going to use to find his son, Baelfire) but Emma then reveals to him that he will create the curse that he hopes will one day find his son Baelfire, and killing Hook will further destroy the timeline. As the pages in the book start to become blank, time is starting to run out for Emma to fix what she has done, and Rumplestiltskin tells her the only way to correct this is to go to the ball that will be held at King Midas' palace.
Seeing that Snow wants passage after failing to secure one from Blackbeard, they hatch a plan to have her steal the ring for passage out of the forest by using Hook’s ship, which means they have to pay a visit to the tavern to distract a past version of Killian Jones, so Hook sends Emma to distract past Hook while he's drinking with his mates. Future Hook suddenly becomes jealous of past Hook for flirting with Emma, as she keeps past Hook occupied while future Hook offers Snow a deal, but things get out of hand when Smee first becomes confused by the difference in his captain, and second when past Hook shows up while future Hook is still there. Emma orders him to leave, and Hook looks on jealously as the past Hook comes on and kisses her. Future Hook then taps his previous life on the shoulder and punches him. Hook replies that he was asking for it, saying that he'll blame the rum for his actions.
Later that night at Midas' palace, Emma and Hook watch to see what happens when Rumplestiltskin appears. He gives them an invitation and alters their looks so they can blend in. As they enter the palace, Emma gives them the aliases "Princess Leia" and "Prince Charles" in front of King Midas, and as they take a waltz together they see Charming and Abigail together but she doesn't want to dance with Charming. The Evil Queen arrives at the palace to ask Midas to search the place just in time for Snow to show up and take the ring. As expected, Charming captures Snow, altering the timeline of the first time they met (and she hits him, this time with a jewelry box instead of a rock). As she makes her escape, Emma sees her running and Charming yelling at her to stop and saying that he'll find her (another altered timeline in their encounter), only to have Emma (who finds the ring left behind by Snow and hides it from plain view) get caught by Regina and arrested. The story continues in the following episode.

Fairytales and Folkore
- This episode features the ugly duckling from the titular fairytale, Robin Hood and Maid Marian from the Robin Hood ballads, Captain Hook and Smee from the Peter Pan story, Snow White, the prince and the evil queen from the "Snow White" fairytale, King Midas and his daughter from the "Midas" myth, the grandmother from the "Little Red Riding Hood" fairytale, Geppetto and Pinocchio from The Adventures of Pinocchio, Rumplestiltskin from the "Rumpelstiltskin" fairytale, as well as Beauty and the Beast from the "Beauty and the Beast" fairytale.
- Mary Margaret says that she saved Prince Charming's life during an attack on the Troll Bridge. The concept of trolls living under a bridge originates in the fairytale "Three Billy Goats Gruff".
- STORYBOOK CONTENT: When Henry flips though the storybook, an excerpt from the fairytale of Snow-White and Rose-Red can be seen next to the illustration of the Troll Bridge.
- Commenting on Zelena]'s fate, Leroy says, "Ding Dong!", and Granny asks, "She's really..?", a reference to The Wizard of Oz song "Ding-Dong! The Witch Is Dead".
- David mentions that the security video tape is Betamax.
- Emma makes references to Marty McFly and the 1985 movie Back to the Future.
- As seen in this episode and "There's No Place Like Home", there are several similarities between Back to the Future and this story, such as the family scene where the story of how the parents met is retold, the child interfering with the parents' first meeting by causing one of them to fall from a tree while a "vehicle" approaches, seeking out a "wizard" to help return to the present (a similarity Emma points out), the visual of the family brought back disappearing after the future is rewritten and reappearing after being set back on course, Star Wars identities being used due to the unfamiliarity of the characters from those in the past, a dance being used as an opportunity to bring the parents together, one parent's enemy disrupting that plan, and keeping the future from those who know of the time travel, but ultimately informing them of a death.
- Black Beard is based on the character of the same name from popular culture.
- Hook's alias in the Enchanted Forest is Prince Charles; a reference to the current Prince of Wales, who is currently first in line for the British throne.
- REUSED PROPS: The bottle of wine that Regina and Robin Hood share is Bordeaux wine from the fictional winery Chateau Baum. "Château" is French for "castle", while "baum" is German for "tree".
- STORYBOOK CONTENT: When Emma flips through Henry's storybook, there is a page about how Prince Charming found Snow White's hideout from "Snow Falls". Note that the last sentence is repeated earlier in the text:

of an oak tree, making it seem as if there might be fire
inside it. But there was no smoke. No great heat from
the massive trunk. He realized this must be it. The
perfect hiding place for a bandit − almost in plain sight.
But the pack also contained rope and netting for setting
traps. And if the Prince worked carefully and used his
material properly. For a moment he was bewildered
and wondered what sort of magic this woman-bandit could posses.

said she was. [sic] Holding out the bag of gold he mutters
"So... You probably want this." Snow turns to him with
the jewels, "And you can't get married without this."
He spills the jewels into his palm. The wedding ring
glistens in his hand. Snow eyes it. "Not your style?"
the Prince chides her. "Only one way to find out."
Snow takes it from his hand and slips it on her finger.
It glistens. A perfect fit and for a moment she thinks...
but no. "Yeah. Not me at all," and she dismisses the
butterflies inside her stomach. The Prince, grateful that
she returned to save his life now knew that Snow White
could never be what the Evil Queen said she was. Hold-
ing onto the bag of gold he mutters, "So...You probably
want this. "So... You probably want this." [sic] Snow turns
to him with the jewels.
- Several artworks by the famous English book illustrator Arthur Rackham can be seen in Henry's storybook:
- "He played until the room was entirely filled with gnomes", from the fairytale collection Little Brother & Little Sister and Other Tales By The Brothers Grimm (1917) (link to page). It depicts a scene from the Brothers Grimm fairytale "The Gnome", and can be seen when Emma looks through the storybook by the duck pond.
- "“Preposterous!” cried Solomon in a rage.", created for the first edition of J.M. Barrie's book Peter Pan in Kensington Gardens (1906) (link to page). It is briefly seen upside-down, while Emma flips the storybook after landing in the Enchanted Forest.
- On the opposite page, a part of "...Fairies away! We shall chide downright, if I longer stay" from a 1908 edition William Shakespeare's A Midsummer Night's Dream (link to page), can be glimpsed. It depicts Titania in a scene from the famous play.
- "The Meeting of Oberon and Titania", an artwork created for (but ultimately not used in) the 1908 edition of A Midsummer Night's Dream (seen when Emma flips through the book in Rumplestiltskin's castle).
- In the same scene, "What did she find there but real ripe strawberries.", also from Little Brother & Little Sister and Other Tales By The Brothers Grimm (link to page), can be seen. This image depicts a scene from the fairytale of "The Three Little Men in the Wood".

- REUSED PROPS: In the captain's quarters aboard the Jolly Roger, there is an urn bearing an almost identical resemblance to the one Elsa comes out of in "There's No Place Like Home"; the only difference being the lid.
- Both of the urns have been used as props in previous episodes in Season Two. They are among Regina's wedding gifts in the Evil Queen's palace in "We Are Both", and a recolored version of both props are used to decorate Cora's heart vault in her home in "The Doctor". The urns also appear in the Frankenstein manor in "In the Name of the Brother".
- Both urns were also used as background props in the Wonderland castle for the filming of the scene where Anastasia attempts to steal the royal jewels in the Once Upon a Time in Wonderland episode "Heart of Stone". However, they do not show up on-screen.

- HIDDEN DETAILS: At King Midas' ball, Emma is wearing the diadem from her father's dream in "The Tower".
- SECONDHAND CLOTHING: The purple coats worn by two of King Midas' servants  are the same coats worn by the Genovia footmen in the 2004 romantic comedy film The Princess Diaries 2: Royal Engagement. The same coats are worn by a bunch of other servants throughout the series:
