Im confused...is there a question?
Dorothy informs him of this in Chapter 4.
"a foil is a character who contrasts with another character, usually the protagonist, to highlight particular qualities of the other character."
so as it seems this should be the correct answer In 49 B.C. on the banks of the Rubicon, Julius Caesar faced a critical choice. To remain in Gaul meant forfeiting his power to his enemies in Rome. Crossing the river into Italy would be a declaration of war. Caesar chose war.
