Who finds a rabbit in the corner?
At the beginning of Act II, Elizabeth and John Proctor are eating dinner. She brings food to the table and tells him it is rabbit. He asks if it came from a trap and she tells him that she actually found it inside the house in a corner.
During this scene, the Proctors are very stiff and formal with one another. The scene sets up the idea that she is still mad at him for his affair with Abigail. His guilt over this affair will be a big deal during the later parts of the play.
I've never heard anyone else say it, but to me the rabbit coming in the house seems unnatural and almost an indication that something is weird in their home.
