Dimmesdale looked pale, weak, and worn out when he met Hester because of the burden of hiding their relationship and his guilt for not confessing his sins. His appearance reflected the inner turmoil he was experiencing.
Dimmesdale acknowledged Hester and Pearl with surprise and compassion, but he could not openly acknowledge them as his family due to his position as a respected minister in the community. His emotions were conflicted between his inner feelings for them and his public image.
Pearl is the daughter of Hester and Dimmesdale and therefore resembles their sin of adultry. Hester dresses pearl in a scarlet colored dress to show this and make her look more like the letter "A" which also resembles their sin.
