"Sisters" is the nineteenth episode of Season Five of ABC's Once Upon a Time. It was written by David H. Goodman and Brigitte Hales, and directed by Romeo Tirone. It is the one-hundredth and seventh episode of the series overall, and premiered on April 24, 2016.
Now that Hades and Zelena are reunited, Hades tells Zelena that he wants a future with her outside of the Underworld. All she needs to do is heal his heart with True Love’s Kiss so they can leave the Underworld and trap the heroes there for eternity. When Regina overhears of this plan, she enlists Cora's help to find a way to separate Zelena from Hades. However, Cora reveals a family secret that could change Regina and Zelena's lives forever. Meanwhile, David finally meets James, only to realize that his twin is determined to seek revenge on him for stealing the life he could have had.

Fairytales and Folklore
- This episode features the Evil Queen from the Snow White fairytale, the Wicked Witch of the West from The Wonderful Wizard of Oz story, the Miller's Daughter from the Rumpelstiltskin fairytale, Captain Hook and Peter Pan from the Peter Pan story, Robin Hood from the ballad, the Prince from The Prince and the Pauper story, Cruella De Vil from The Hundred and One Dalmatians story, and Hades from Greek Mythology.
- The number 15 appears on a pavement sign outside the Underbrooke version of the Marine Garage; a reference to the third Lost number.
- The way Zelena asks Cora if she is a "good witch" is a reference to the 1939 film The Wizard of Oz.
- The song "I Don't Want to Set the World on Fire" by The Ink Spots plays in Hades' car radio during his date with Zelena. Hades plays the song again on the Underbrooke Diner's jukebox, as he prepares for another date.
- When Cora opens the Book of Spells, one of the illustrations is a slightly modified, upside-down version of the seal of Marbas, an illustration from the Lesser Key of Solomon, a spell book on demonology published in the 17th century. Marbas is a demon who is described as the Great President of Hell, governing thirty-six legions of demons.
- At the Underbrooke Docks, when James gets up after David pushes him to the ground, in the background, you can see the Enchanted Cuff lying on the ground next to Emma and Hook, indicating that Hook used his hook to remove it from Emma's wrist off-screen, just like Cora used it to remove her own cuff earlier in the episode.
- Prince James is wearing a Belstaff H Racer Jacket in black. When his twin brother David escapes from the sheriff's station, he is wearing the same jacket (because James stole David's own jacket in order to impersonate him).
- Interestingly, David continues to wear his deceased brother's jacket in the next episode, "Firebird", and even takes it with him when he goes back to the Land Without Magic. He continues to wear it in "Last Rites", "Only You" and "An Untold Story", and the Season Six premiere "The Savior".
- Robin Hood wore a green version of this jacket in "Heart of Gold" and the last three episodes of Season Four, as well as almost every episode of Season Five, including this episode. Robin Hood's Wish Realm counterpart, Robin of Locksley, also wears this jacket in the Season Six episodes "Murder Most Foul", "Ill-Boding Patterns" and "Page 23".
- The black jacket was also worn by Lance Hunter in the Agents of S.H.I.E.L.D. episode "Purpose in the Machine".
- The dress worn by Cora in her last two flashback scenes at Royal Manor is the same dress that she wears for the scene where Anastasia tries to run away in the Once Upon a Time in Wonderland episode "Heart of the Matter", but with different embroidery.
- Zelena's date with Hades was filmed in Garry Point Park, a large 75 acre waterfront park located close to Steveston Village, which doubles as Storybrooke and Underbrooke on Once Upon a Time.
- The Woodcutter's cottage is a redressed version of the Apprentice's cottage from Season Four. The same set doubles as one of the cottages in the village of Camelot in "The Broken Kingdom" and Brennan's cottage from "Swan Song". Although the set has been heavily redressed to double as the Woodcutter's home (most noticeably, the roof has a completely different shape, and the chimney is in a different position), the door, the window panes and the pattern of the brick stones (the ones around the window are easiest to compare) are the same.
- The cottage was also reused for Fiona and Malcolm's cottage in the Season Six episode "The Black Fairy". This can be seen from the identical pattern of the brick stones (the ones on the right hand side of the lower half of the door are easiest to compare). The Apprentice's roof tiles were replaced with a thatched roof for the episode.
- Burnaby's Central Park doubles as the Underbrooke Woods for this episode.
