Amanda Whitaker is Faye's little sister. She first appeared at Marten's apartment after being kicked out of home by her mother for being a lesbian (among other things), but after talking to her mother she moved back in.
Amanda is a college student majoring in modern dance, a major she switched to from pre-med.
According to Faye, she has never held a job.
- "That was the day I learned that there's no way you can remove your head from another girl's crotch in a nonchalant manner."
- "Well, let's just say mom didn't take too kindly to the news that I'm switchin' majors from pre-med to modern dance, or that I failed all my classes last semester, or that I'm a lesbian."
- "Yeah it's nice to occasionally be reminded that I'm the SANE daughter."
- "Holy shit, you did get buff!"—talking about Faye's muscles.
