Who puts the blanket around Scout's shoulders?

Atticus reads to Scout, who wakes up while he carries her to bed. She tells him she was listening all the time, and that the book is about a character who was chased and caught and then found to be innocent and "real nice." Atticus tells her, "most people are, when you finally see them." Atticus then spends the rest of the night by Jem's side.
