This is a longitudinal self-study of a mentoring relationship that emerged and evolved between a graduate research assistant and a professor over seven academic years. We use social exchange theory to explore the evolution of this relationship. Specifically, our focus is a series of nine revealing moments that demonstrate evident learning, a relationship change, or shifts in the currencies of exchange over time. These revealing moments arose from intentional opportunities for scholarly development, personal and relational interactions, and unanticipated occurrences. This study exemplifies the dynamics of a mentoring relationship over an extended time period, thereby responding to the dearth of longitudinal studies of mentoring internationally.
