I've always wondered why it wasn't shown. I don't think it was for anything criminal (Sintia) or legal action (Amy R, Erica). I just don't buy that it was not shown because of lack of time. Maybe she withdrew by phone/email or got violent and had to be walked out. Just my guesses.
EDITED: found this about her:
