In act 3, in court, Abby first acts in self-preservation, tormenting Mary until she breaks down and the other girls are caught up. When Mary, to protect herself, in turn accuses Proctor, hysteria overtakes the adults as well.
Abby is running out of options to defend herself from charges of lying to cover up her affair with John. She cries out wildly toward the roof, claiming to see a bird behind the rafters.
As the other girls say they see it too, Abby addresses it as Mary's spirit, pleading that it not harm her.
