First, Dimmesdale becomes Chillingworth's "spiritual guide"; Chillingworth presents himself as one who is "exemplary [...] at least, [in] the outward forms of a religious life." It is important to Chillingworth's plans for revenge on Hester's co-sinner, and Pearl's father, to appear to be upstanding and moral. He does not want anyone to suspect him of wickedness because this would undermine his plans. Around this same time, "the health of Mr. Dimmesdale had evidently begun to fail." Dimmesdale grows pale and emaciated, and people begin to think that he is quickly nearing death, especially as he always lays his hand over his heart, as if it pains him. People in town come to the conclusion, then, that Chillingworth's timely arrival is "providential" and "opportune," to say the last. Chillingworth claims to feel certain that he can help the minister's health improve, and everyone is so in favor of the minister receiving his help that they end up becoming roommates.
