"With these words, she advanced to the margin of the brook, took up the scarlet letter, and fastened it again to her bosom. Hopefully, but a moment ago, as Hester had spoken of drowning it in the deep sea, there was a sense of inevitable doom upon her, as she thus received back this deadly symbol from the hand of fate. She had flung it into infinite space!-she had drawn an hour's free breath!-and here again was the scarlet misery, glittering on the old spot! So it ever is, whether thus typified or no, that an evil deed invests itself with the character of doom. Hester next gathered up the heavy tresses of her hair, and confined them beneath her cap. As if there were a withering spell in the sad letter, her beauty, the warmth and richness of her womanhood, departed, like fading sunshine; and a gray shadow seemed to fall across her. When the dreary change was frought, she extended her hand to Pearl. 'Dost thou know thy mother now, child!' asked she reproachfully, but with a subdued tone. 'Wilt thou come across the brook, and own thy mother, now that she has her shame upon her,-now that she is sad?' 'Yes; now I will!' answered the child, bounding across the brook, and clasping Hester in her arms. 'Now thou art my mother indeed! And I am thy little Pearl!'"(Hawthorne 162-163).

Before this quote, Hester and Dimmesdale had decided that they were soon going to runaway back to England, and in a moment of pure joy Hester unfastened the scarlet letter and threw it into the woods. When Pearl returns to her mother she sees that the A is missing from her mothers chest and throws a tantrum until it is replaced. The fact that the letter was missing from her mothers chest was so unsettling to Pearl because Pearl is the human form of the scarlet letter and when Pearl returned to her mother and Dimmesdale she already felt like an outsider. Between feeling like she no longer belonged and the absence of the A Pearl felt that if her mother could just toss away the A, something she'd worn ever since Pearl was born, then maybe she could just toss Pearl away at the same time, and not even look back. For Pearl's sake Hester put the A back on her chest and Pearl stopped screaming and hugged her. On a deeper level Pearl represents truth and she wants to make Hester accept her sin and be able to tell the entire town before she is allowed to remove the letter once and for all. Pearl was not going to let Hester remove it for the wrong reason, and therefore became angry and stubborn when the letter disappeared. No matter what Hester does there is no way that she can accept her sin, until she stops running away from the truth. Even though she took the letter off for a brief hour, every time she looks at Pearl she is reminded of her sin just the same. The reason that Hester was even allowed to keep Pearl in previous chapters was because Dimmesdale said that the child was a constant reminder of Hester's sin. By making her mother wear the scarlet letter Pearl is letting her know that no matter what, Hester is not really free until she and Dimmesdale let the town know who the father is.
"But, whether influenced by the jealously that seems instinctive with every petted child towards a dangerous rival, or from whatever caprice of her freakish nature, Pearl would show no favor to the clergyman. It was only by an exertion of force that her mother brought her up to him, hanging back, and manifesting her reluctance by odd grimaces; of which, ever since babyhood, she had possessed a singular variety, and could transform her physiognomy into a series of different aspects, with a new mischief in them, each and all.The minister-painfully embarrassed, but hoping that a kiss might prove a talisman to admit him into the child's kindlier regards-bent forward, and impressed one on her brow. Hereupon, Pearl broke away from her mother,and, running to the brook, stooped over it, and bathed her forehead, until the unwelcome kiss was quite washed off, and diffused through a long lapse of the gliding water"(Hawthorne 164).

Right before this quote in the novel Pearl asks Dimmesdale, for the second time, if he plans on walking back into town hand in hand with Hester, and he once again, refuses. Throughout the novel Pearl represents the truth of the sin that Hester and Dimmesdale committed and all she has wanted was for them to expose it to the town. Back in chapter sixteen the sunlight avoided Hester because she was hiding a secret and not being truthful to the community, but the sunlight had no problem shining down on Pearl. This image depicts the saying to "shine a light" on a situation. The saying means to tell the truth and the fact that the sunlight only shines on little Pearl, foreshadows that the truth needs to come out, and it will come out one way or another. Dimmesdale tries especially hard to hide and deny the sin that he has committed because he will not publicly show himself with Hester and Pearl. When Dimmesdale kisses Pearl it is as if he is trying to cover up or besmirch the truth that is Pearl. Since Pearl wants the truth to be revealed she feels that she needs to rid herself of the smudge on her face and cleanses her forehead of the clergyman's kiss in the brook. By washing off Dimmesdale's kiss, Pearl is implying that she will not accept him in her life until he acts fatherly towards her, and in order for him to act fatherly he must confess his love and sin to the public.
