"Things between Max and Liz are still complicated since she had to trick him into falling out of love with her for the sake of the world. (Who can’t relate to that weight of the world on their shoulders?) As a result, they haven’t even really been friends since then. It takes this haunting guilt to drive Max back to Liz’s window, where she is just happy to see that Max is starting to consider her a friend again. […] Just like Liz was the voice of reason for Maria, she serves the same purpose with Max when he comes back to visit her the day after his hospital visit. She tells him that what he did was amazing but he can’t make it a habit. “You’re not God, Max. You told me that,” Liz says before inviting Max to midnight services with her. His parents also wanted him to join them there, but he tells Liz that he doesn’t believe in God. A final exchange with the ghost changes Max’s mind, and he shows up as the choir starts singing “O Come All Ye Faithful.”
Liz: “I thought you didn’t believe in God.”
Max: “I believe in you.”"
