Detailed Explanation
Bonnie Carlson killed Perry Wright, though "murder" is complicated here. When Perry began attacking Celeste in front of everyone at trivia night, Bonnie pushed him down the stairs. He died from the fall. What makes this death particularly resonant is that Bonnie, the most seemingly zen and peaceful of the Monterey Five, is the one who acts with violence—and she carries the trauma of that moment throughout Season 2. The show explores how protecting others from abuse can create its own lasting psychological damage.
