nah, you have to remember that her & sonny have been together for over 10 years. from teenagers to young adults to adults in their late 20s. she knows sonny, at the end of the day. if anything, the theory just reminded her how well she knows sonny, what motivates him and what his insecurities are.
it definitely won’t be a situation he can just apologize and resolve, but they have the benefit of a lot years together. she takes the theory at face value for what it really is– some kind of reminder that sonny is motivated more often by his love for her than he is by almost anything else. even the club.
