‘I took him by the hand, a hand surprisingly warm for its whiteness.’

Here Scout first mentions how the ideas and assumptions she had of Boo are different to reality. She assumed his touch would be icy cold like that of a stereotypical ghost. However, his touch was warm which symbolises that there is warmth beneath the surface, that there is more to Boo that has yet to be explored. Beneath his intimidating exterior shell, there is a kindness and warmth about him. His hand was warm which symbolises the pleasant personality he possesses despite his protective outer shell which he barely comes out of.
