Evan eventually returns home, and reunites with his mother Heidi. Julianne Moore’s matriarch tells him she loves her son no matter what with the heartbreaking song “So Big/So Small.” Ben Platt’s character admits to his mother that his fall out of the tree was actually a suciide attempt. And to make sure the Murphys are left alone, he posts a public confession and apology online, before going back to his regular, isolated life. Evan once again sits alone at lunch, and finishes up his high school career quietly.
