Amelia's innocence and ready belief in other people make her unbelievably good in contrast to Becky's unbelievable duplicity. Both attract young men, but for different reasons. Becky's wit and physical charm win a following, whereas Amelia's goodness and sweetness charm all who meet her. Becky can cry when she wants to; Amelia cries over a dead canary, a mouse, the end of a stupid novel, or the slightest unkind word to her.
She remains blind to Dobbin's goodness throughout much of the book and although her eyes have been opened to a certain extent regarding Becky, yet when she thinks Becky needs a friend, she returns to comfort and help her.
Amelia depends on others for her opinions, and this is why it takes a sharp companion like Becky to set her straight — to make her see realities. One negative reaction was jealousy of George, and she had ample reason for that emotion, but it did not lessen her love for him. At the end of the book Thackeray calls her a "tender little parasite." She has changed little from the beginning of the book. Sheltered as she has been, she has had little chance for growth.
