Although being aware of one another almost from the time Andrea and Brandon meet, they don't officially meet until Andrea comes over to the Walsh home to study for a history test. Brenda is acutely aware of Andrea's crush on Brandon, especially given that Brandon confides in Brenda about his relationship with Andrea. After they bond over working at the rap line, Brenda makes an effort to include the, at times, socially awkward Andrea. Over time the four girls become a group, with Andrea and Brenda always the more grounded duo. They are both ambitious, strong women with core values that they fight to uphold and, whenever they team up, the outcome is usually course altering and powerful.
