"The first was that Annie Wilkes had a great deal of Novril (she had, in fact, a great many drugs of all kinds). The second was that he was hooked on Novril. The third was that Annie Wilkes was dangerously crazy" page 10.
The first indication of the "other" side of Annie's character appears two weeks after the accident when she asks Paul can she read the manuscript in his leather bag. The following day when she enters his room to feed him some soup she tells him she has read 40 pages of his "manuscript book" and it is not as good as his others.
After a few comments she launches into a tirade about the profanity in the book:.
"And the profanity! Every other word is that effword! It has no nobility!" she cried suddenly, jumping and almost spilling beef-barley soup on his white, upturned face.".
She becomes upset to the point that one, then two drops of soup fall on the coverlet. A little more ranting and then more soup spilt on the coverlet;.
"There! Look what you made me do!".
"I"m sorry.".
"Sure! You are!" she screamed, and threw the bowl into the corner, where it shattered. Soup splashed up the wall. He gasped.
She turned off then. She just sat there for what might have been thirty seconds. During that time Paul Sheldon's heart did not seem to beat at all.
She roused a little at a time, and suddenly she tittered.
"I have such a temper " she said.
"I"m sorry" he said out of a dry throat.
"You should be.".
When Annie gets upset she is very much Dr Jekyll and Mr Hyde. One moment personable and calm then ruled by rage and anger.
As the story develops Annie becomes more domineering, more irrational and has Paul fearful for his future. She feels in control of the situation and comfortable in the knowledge that Paul is her prisoner.
Her anger erupts further when she finds that her beloved Misery Chastain dies in the end of Paul's last book. .
"She can't be dead!" Annie Wilkes shrieked at him. Her hands snapped open and hooked in a faster and faster rhythm.
