Mother Rui made a decision almost immediately— she had to take Rui Ye away from this island, the further the better! She must not let them get caught!
Alas, while she had the will and determination, her means were severely lacking.
Let's not mention where they should go after they left the island – she was still young, hardworking, with none of her limbs missing, so she didn't mind having to suffer as long as she could feed and clothe her son – the main and biggest problem was, could they even leave? That monster had taken over the Chief's appearance and bewitched everyone here. It was apparent from how seamlessly he had integrated into the village to the point where no one had ever suspected him, not even his own family!
Even if she were to speak out and tore his mask apart, would anyone even believe her? She did not even need to think; the answer was a solid— no.
