Uncle Fester is Kaisa's alter ego, emerging particularly when she has inhaled or is under the influence. This endearing alter ego is characterized by a charming disposition, often accompanied by facial redness and sometimes even dark under the eyes if she had mascara on for the evening.
"Uncle Fester makes a grand entrance when Kaisa's had a date with her favorite bottle of laughter-inducing spirits, leaving behind a trail of giggles and maybe a misplaced shoe or two."
