Dimmesdale goes to the scaffold where Hester Prynne had lived through her public ordeal.
He stands there just waiting for someone to throw rotten fruit, but no one shows up.
(Maybe next time try going during the day, dude.)
He gives a little shriek, trying to rouse people to come shame him, but the only people who stir are Governor Bellingham and his sister.
Mistress Hibbins (the witch-lady from chapter 8) hears him, but the narrator tells us that she probably thinks that it's just her friendly neighborhood witches making a ruckus.
Dimmesdale calms down enough to notice that his friend and fellow clergyman Reverend Mr. Wilson is approaching.
He's coming from the deathbed of Governor Winthrop, looking all holy and saint-like with the glow of the lamp like a halo surrounding him.
He doesn't notice Dimmesdale lurking up on the platform, and Dimmesdale doesn't speak.
Dimmesdale imagines what would happen if he were still there in the morning, and he's apparently tickled by imagining his community discovering that their beloved minister is a huge sinner because he busts out laughing.
Surprise! Pearl laughs back at him.
He calls out and Pearl responds. Hester is also with her. They're heading back from Governor Winthrop's house, where she's measured his body so she can make his burial robe.
The two join him on the scaffold.
Dimmesdale and Hester are connected through Pearl, as each holds one of her hands.
Pearl asks him if he will stand with her and her mother tomorrow at noon.
