[Chapter 41] How does Twain create pathos in this chapter?

I think the whole idea of Aunt Sally waiting is silence for Sid's return is filled with pathos.During the night, Huck sneaks out several times and each time sees her sitting with a lit candle on the front porch, waiting for Sid's return. Huck feels very sorry for her and wishes he could tell her everything. THe scene is touching and sad.
