The conflict in this scene is entirely internal. In many ways the novel, The Adventures of Huckleberry Finn, was leading up to a moment such as this one right from the beginning. For the whole of the story the readers see Huck struggling with what society tells him is the right way to do things and how he often feels the exact opposite. Huck’s inner turmoil is seemingly infinite up until the moment he writes Miss Watson a letter, one that would lead to Jim’s re-enslavement. He is content for a moment after finishing the note that would sentence his new best friend back to a lifetime of suffering. Upon realizing the consequences the letter would create for Jim, Huck promptly shreds what would have been his way out of the external conflict happening
