Warning: This list contains spoilers for The Haunting of Hill House.

Fans of the Netflix series The Haunting of Hill House are diving deeper into all aspects of the show - including its psychology. Shortly after the release of Season 1, dozens of fan theories surfaced on the internet about the plot and the characters' motivations. One theory by Tumblr user cagedbirdsong has been particularly well-received, to the point that even the show's actors and director Mike Flanagan chimed in with their thoughts.

According to the theory, each Crain sibling represents one of the five stages of grief: denial, anger, bargaining, depression, and acceptance. For those unfamiliar with the Kübler-Ross model, psychiatrist Elisabeth Kübler-Ross developed it in the 1960s to help explain the typical grieving process. Not everyone grieves in the same way, but patterns of grief do emerge. The five stages are meant to help people figure out how they are processing a severe loss, but the model is by no means a roadmap for how people should grieve.

This list takes a more in-depth look at the five Crain siblings and all the evidence in the series that proves they each represent a particular stage of grief.
