Helen Back Again Victorious : Season 2 Episode 7

Principal Eichner marries a young Tahitian woman and quits his job as Hollywood Arts principal to run away with her. His replacement is none other than former child star and San Diego Premiere movie theater owner Helen Ophelia DuBois(see Drake & Josh (2004)) who demands that all of her students re-audition in order to stay at school, which doesn't bode well for one of the Vega sisters... and it's not who you might think.
