Chapter 37

Escape is the thirty-seventh chapter of The Promised Neverland. It is adopted into Episode 12 of the anime.

Synopsis
The children managed to escape from the Grace Field House.

Plot
This chapter marks the end of Emma and Ray's escape plan, having escaped with a majority of the older children. A brief backstory of Isabella is shown regarding how she found out the truth about the plantation and was quickly integrated into being a Mama, getting pregnant and giving birth off-screen, then being installed as Mama of Plantation #3. It is also exposed that Ray is her biological son, which Isabella discovers when she hears Ray hum her favorite melody that she did while she was pregnant, showing how Mamas do not know what happens to their children after being sent to a plantation. Ray being Isabella's son reveals the reason for his shifty and self-loathing personality, along with the reason as to why Isabella gives him a lot of freedom despite him just being her informant.

Isabella has a brief moment of flashbacks, smiling and noting that it is her defeat and how she only wanted to survive. She thinks to herself that she really wished she could have loved the children normally and bids them farewell, later helping hide any evidence of the methods of Emma's group's escape as there is no way she can catch up now with the ropes cut. She briefly informs Phil that they all made it out safely before gathering the other kids and singing them to sleep. She notes that she did all she can do to ensure that the demons' forces will be hunting within the plantations by hiding evidence that they jumped the gap.

Trivia

 * The date at the end of the chapter is January 15, 2046.
 * This chapter ends the Jailbreak Arc.
 * The finalized version of chapter 37 had a lot of quotes that weren’t brought up in Shirai’s meeting with Sugita before writing it. Shirai says writing this chapter was difficult. He wanted to draw Isabella’s true face and her facade twice in a single chapter, but it was becoming complicated so he decided to remove it. Eventually, he did draw her multifacetedness but faced difficulty in deciding how much of it would be shown.
 * Chapter 37 reveals that Ray is Mom’s real son (Another scene for which Posuka commented Shirai is "dark"). Shirai is happy with the timing of the reveal. There were locations where this revelation was supposed to take place. But Shirai removed them all and put it here, and he thinks this was the correct choice.
