Although she was a good friend of the Rooster Teeth production crew, Burnie Burns intended to allow other women to audition for the role of Sister despite the pressure of the other members. He notes two other girls auditioned for the role before Frasier was given her chance, but when she began auditioning the team made something of a joke out of the audition, slipping in more and more lines of dialogue which got increasingly more vulgar to see how far Frasier would go before refusing to do a line. Upon realizing she had no such limits, Frasier was cast as Sister and the role was re-written as a far more promiscuous character to fit with the lines she had read in the audition.
She later became RT's Website Content Manager. On her Twitter, Frasier noted her daughter was born on October 30, the same day Sister made her debut on Red vs. Blue. Becca also was expecting her second child while recording Season 16.
She left Rooster Teeth on January 3rd of 2020.
