Shortly after Ed Warren is "possessed" by the Occultist towards the end of the film, he picks up a hammer and begins running through the tunnels looking for Lorraine. Everything about this scene, from Patrick Wilson's costuming as Ed to how he holds the hammer, feels like a parallel to the Jack Torrance chase scene in The Shining. All that is missing is Wilson yelling, "Here's Eddie!" Although that might have been out of character for the demonologist . . . even if it wouldn't technically be him saying it.
