In The Crucible, what are some quotes that show Abigail Williams losing power?

From the
beginning of the play, we see that Abigail Williams's grasp on power is tenuous. When Reverend
Parris's daughter, Betty, comes out of her "coma," she says to Abigail,

You drank blood Abby! You didn't tell him that! ... You did, you
did! You drank a charm to kill Proctor's wife! You drank a charm to kill Goody
Proctor!

Abigail becomes infuriated and threatens Betty.
Why does she do this? It's because Betty speaks the truth. Abigail knows that the one thing her
pretense of godliness can't withstand is the truth. She therefore tries to silence and bully
Betty and the other girls, but the audience knows that Abigail's power is only a thinly
constructed facade.

The next glimpse the audience sees of Abigail's anemic
grasp on power is when Reverend Hale visits the house of John and Elizabeth Proctor. In the
process of Hale's interview with the Proctors, John reveals that he knows the girls are just
pretending. Proctor tells Hale that the girls were caught being mischievous in the woods, were
startled, and then pretended to be sick.

Hale: Who told
you this?

Proctor, hesitates, then:
Abigail Williams.

Hale: Abigail!

Proctor:
Aye.

Hale, his eyes wide: Abigail Williams told you it
had naught to do with witchcraft!

Proctor: She told me the day you came
sir.

This exchange may seem insignificant, but it's an
instance of the truth coming out.is making the point that eventually the truth will be
victorious. Falsehoods cannot bear the beacon of truth. Miller also takes great pains to point
out how well-respected Reverend Hale is because of his religious education at Harvard
University. If Hale, someone so respected, comes to believe the truth of what Proctor is saying,
Abigail's house of cards will come tumbling down. Her semblance of power will crumble.

The dramatic instance that blatantly displays Abigail's loss of power comes in act 3,
when Mary Warren appears before Danforth at Proctor's demand in order to expose Abby. Proctor
becomes fed up with Abigail's manipulation, bullying, and false self-righteousness, and in a
fury, he exposes her:

(Director's notes) Without
warning or hesitation, Proctor leaps at Abigail and, grabbing her by the hair, pulls her to her
feet. She screams in pain. Danforth, astonished, cries, "What are you about?" and
Hathorne and Parris call, "Take your hands off her!" and out of it all comes Proctor's
roaring voice.

Proctor: How do you call heaven? Whore!
Whore!

Herrick: John!

Danforth: Man! Man! What
do

Proctor: It is a whore!

Danforth: Do you
charge?

Abigail: Mr. Danforth! He is lying! ...

Danforth:
You will prove this! This will not pass!

Proctor: I have known her sir. I
have known her.

Danforth: YouYou are a lecher?

And then the whole ball of yarn comes unraveled. For Proctor to say that he has
"known" Abigail is an antiquated term meaning that he has had sex with her. John
Proctor has just cast his reputation and name away in order to prove that Abigail is a
manipulative liar and has illegitimately been given power. In the the era of the Puritans, no
Christian man would risk his reputation, name, and honor to falsely say that he had committed
adultery if it weren't true. Everyone at that hearing knows this, and this is whythough there
are a few more weak attempts by Abigail to hold on to powerthis is her death
knell.
