In Act I of The Crucible, when Abigail is questioned by Reverend Hale, who does she blame? What proof does she offer?
Abigail blames Tituba, Reverend Parris's Barbadian slave, for Betty Parris's and Ruth Putnam's strange illnesses. She knows that her uncle, the reverend, saw Tituba chanting and swaying in the woods, and she knows that Mrs. Putnam believes that Tituba has the ability to conjure spirits, so it won't strain anyone's credulity to hear Abigail accuse the slave of witchcraft. As a slave, and as a woman, there are two strikes against Tituba; she is powerless and suspect already. By way of proof, Abigail claims that Tituba made her drink blood. She also says that Tituba sent her spirit to Abigail at church, and that she made Abigail laugh during prayer (a fact that Parris confirms). Further, Abigail says that Tituba bewitches her in the middle of the night so that Abigail awakens naked, having heard Tituba laughing and singing her songs from Barbados.
In Act I, when Hale pressures Abigail for an answer to who was practicing witchcraft,Abigail blames Tituba for being a witch. Abigail points at Tituba and says:
"She made me do it. She made Betty do it."
When Tituba denies this, Abigail goes further with the accusations saying that Tituba sends her spirit out on her and makes her laugh at prayer. Abigail even goes further to have the authorities believe her by saying that Tituba makes her "drink blood." This is important because these accusations are easily believed about a slave woman from Barbados. This starts the "snowball" effect of accusations of witchcraft because Tituba, out of fear, begins to name other townspeople as witches also.
In Abigail's initial interview by Reverend Hale he is asking her about her dancing in the forest. She tells him that she had never called the devil but Tituba had called him.
Tituba is questioned by Hale and denies calling the devil. Abigail then tells the Reverend that Tituba made her drink blood as well. The woman does not deny this and states that she had given her chicken blood not human blood. She tries to deny any connection with the devil.
Later in the story Abigail is again questioned by the Reverend. She blames Elizabeth for putting a needle in a doll and causing her pain.
