Starting from page 12, Dill Harris appears throughout the story as a good friend of Jem and Scout. The following quotes come from their first few meetings.
Dill first introduces himself to Jem and Scout as "Charles Baker Harris," telling them: "I can read."
On page 13, he states:
I just thought you'd like to know I can read. You got anything needs readin' I can do it.
Jem gives him the cold shoulder until Dill tells him he has seen Dracula. Their conversation then moves on to books and films. On page 14, Scout asks Dill where his father is. Dill replies:
I haven't got one.
On page 18 and 19, Dill becomes interested in the reclusive Boo Radley. He asks
Wonder what he does in there?
Wonder what he looks like?
On page 19, he tries to persuade Jem to go up to the Radley's house by saying,
You're scared [. . .] You're too scared even to put your big toe in the front yard."
He further challenges Jem on page 20 by saying,
You gonna run on a dare?
On pages 20 and 21, he tries to reassure Jem by telling him he and Scout will help him out if Boo tries to attack him.
Scout'n' me'll jump on him and hold him down till we can tell him we ain't gonna hurt him.
