Katie, along with Nicky Farina and Eric Little enrolled in Bayside in season 4, following the departures of Tommy D, Lindsay, and R.J.
Katie had an on/off relationship with Nicky.
Katie's older sister, Robin is also a Bayside graduate.
Like Jessie Spano and Megan Jones, Katie is also the smartest girl in school.
Katie's Arthurian archetype is similar to that of Morgan le Fey, though mostly relying on earlier accounts of her being an enchantress/sorceress, she also incorporates accounts of her caring for the fatally wounded once and future king Belding.
