The most plausible ending for Lilly

I really do think that Lilly will survive and grow up to become the polar opposite of Ingrid. While Ingrid sense of compassion is just facade for her true insidious and selfish intention. Lilly will grow up and work in Juniper Hill to provide an actual genuine compassion and empathy toward those who are experiencing what she experienced during her youth.

We probably even got a POV perspective of Lilly in one of the trailer where she saw Bev comforting her dad because her mom hanged herself in Juniper hill. Lilly providing Bev with love and reasurrance ia 100% going to happen in the finale which also parallels the first scene between Lilly and Ingrid.
