Quote #4

And with low voice and doleful look
These words did say:
"In the touch of this bosom there worketh a spell,
Which is lord of thy utterance, Christabel!" (265-268)

Geraldine flat-out tells Christabel, "I put a spell on you!"

Quote #5

A snake's small eye blinks dull and shy;
And the lady's eyes they shrunk in her head,
Each shrunk up to a serpent's eye
And with somewhat of malice, and more of dread,
At Christabel she looked askance!—
One moment—and the sight was fled! (583-588)

Is what Christabel seeing here real, or in her head? How can you tell?
