In "The Scarlet Letter," chapters 11 and 12, what did Pearl ask Reverend Dimmesdale?

Pearl asks Dimmesdale if he will stand upon the scaffold during the day with her mother and herself.  To do so would be for Dimmesdale to confess.  It is Pearl throughout the novel that goads Dimmesdale into revealing his sin, and it is to her at the end that he turns when he finally does, looking for forgiveness.  At this point, however, Dimmesdale shrinks from the question.
