Before Brett knew he was gay, he was in a romantic relationship with Christie. They lost their virginities to each other when they were together. After breaking up, due to Brett coming out, they still maintained a friendship with each other. The two of them shared an interest in The Real Housewives, which is what bonded them so tightly. In The Real Third Wheel, Brett introduced her to Kenny and they had a friends night out, which also included Allison. Kenny was oblivious to the fact that they were sexually or even romantically intimate with each other, until she accidentally admitted it. Brett kept this a secret from Kenny because he wanted Kenny to know that what they had was special, and what he was with Christie cannot compare to what they have now.
