In the characters' past
At the location of the portal where she was supposed to meet Henry, Cinderella encounters Lady Tremaine's guards. However, the guards were attacked by Cinderella and at the last minute are ambushed by Princess Tiana, who happens to be the leader of a resistance group. As the two forged an alliance upon meeting each other, Tiana tells Cinderella that the prince killing her father was planned by Tremaine. As Cinderella agreed to join Tiana, she also left behind her glass slipper for Henry to find. The following day, Tiana informed Cinderella that Tremaine has moved something that they can't identify to her manor, but Cinderella knows what it is but says that she doesn't. Soon they're joined by Henry, Hook, and Regina, who Tiana believes the latter can prove valuable in their fight against Tremaine.
That night, Cinderella made a secret return to the manor to confront Tremaine over why she murdered her father, but Tremaine explained that it was Cinderella's fault as she revealed a coffin that she had moved earlier, which contained the preserved body of Tremaine's daughter Anastasia. Tremaine offered a deal to spare Cinderella and the resistance on the condition that she steal Henry's heart because Anastasia needs a heart full of belief in order to be revived. This puts Cinderella in a dilemma, so she uses another idea. The previous day, Tiana introduced Cinderella to a resistance member who is ready to devote himself to the cause, but when Regina sees what Cinderella was planning to do, she stopped her, telling Cinderella that doing so would be a major mistake. The next day, Regina catches Cinderella trying to run away, then gets to open up about her relationship with Tremaine. Cinderella tells Regina that her father's death is tied to Anastasia's and her own involvement led to Tremaine's hatred for her. Regina suggested to Cinderella that the only way to fight back is to use forgiveness, and Cinderella agreed to stay with the resistance, just in time to warn them about Tremaine's plot, and eventually put the plans on hold for now.
In Seattle
At the community garden, Jacinda is still upset over being separated from Lucy as she shared letters between the two with Sabine about protecting the garden. However, Victoria shows up at the garden and is ready to replace the lot with a new building and refuses to listen, even if it is for Lucy's sake. After stopping by Roni's, Roni tells Jacinda the only way to stop Victoria's plan is to launch a petition that would lead to an injunction in order to prove that the garden is viable to the community. The petition campaign gathers enough signatures for Jacinda to get the injunction, but Victoria shows up with an offer to give up the petition in favor of giving her a condominium for her and Lucy. Unfortunately, when Lucy sees this, she turns on Jacinda for giving in to Victoria's scheme. Hours later and after getting advice from Roni, Jacinda decides to fight back against Victoria by gathering the residents to sign the petition, which impresses Henry and Lucy.
Lucy suspects that Victoria is trying to destroy the garden because she might be hiding something. When an excavator hits an object that they cannot break, Lucy believes that there's something at the bottom of the site and jumps into the hole and Henry follows. As Lucy continues to ask Henry about where his family was buried, she comes across a piece she believes was from Cinderella's glass slipper, and she gives it to Henry as proof that Jacinda was Cinderella and starts to somehow believe her. However, later that night Henry goes to a cemetery and finds the headstones of his late wife and child.
