Hours later, Zelena helps Regina remember how to isolate the part of the potion that stops time, which they hope can buy them more time to stop Fiona. Unfortunately, just as they are about to enact the spell, Gold uses it on Emma's family. Emma goes to confront Fiona at the Mayor's office, but Fiona holds Emma's family hostage, save for Henry, along with Regina, Zelena, and Hook. Fiona taunts Emma by playing her the song from her childhood, which reminds her of a time when she was alone. Henry, upset that Emma has decided to turn over her heart to Fiona, throws down his book in rage, only to discover a page in the book that reveals that Emma's heart was gifted with the magic of song, placed there by The Blue Fairy. When Emma meets with Fiona, she rips out her heart but is unable to crush it. Henry rushes in to stop his mother, telling her that she has a song in her heart, which suddenly emboldens Emma as her music starts to strengthen her ("Emma's Theme"). This causes Fiona to try to kill Emma with a blast of Dark Magic, but she fails. Emma then uses her magic to free everyone. As Henry returns Emma's heart to her, Fiona tells her that they will still face each other in the Final Battle.
