In this flashback conversation between Gabby and Jess, the audience learns that Jess never wanted a life of violence. The moment doesn't represent a major shift in the ways that the characters view each other, they already assume that the other person is equally unhappy in their situation, but it's very telling about them to the audience. In the face of all the fear and suffering that they undergo on a day-to-day basis, even something as mundane as accounting feels like a blessing. It also helps to reinforce, just in case the audience wasn't paying attention, that Lost Vegas is an absolute wasteland sans electricity and motors.

Although it isn't the most dramatic reveal of the act, the reveal that Don Diego's charm was, in fact, an important artifact solidifies for the reader that he is, even posthumously, a figure of surprising skill and trickery. His deceitful spirit (as indicated by his nickname "The Fox"), affects everyone that he meets, for better or for worse. In this sense the charm acts as a blessing, and as a reminder to the audience that the world of these characters is full of a magic and mystery that can happen at any time. even from beyond the grave.
