Bonnie is the younger sister of McMurray. McMurray often suggests to Wayne that she and Wayne would make a good pair. Bonnie is herself attracted to Wayne, and mentions that she wished she could have a dance with him when watching him and Angie dance. When home from school she worked as a cashier at the dollar store, and tells him to take ice without paying. When Wayne and Katy hold interviews to see the best way to spend their inheritance from Uncle Eddie, she narrates each contender unbidden ("Uncle Eddie's Trust"). Wayne is discomfited, however, given their age difference ("The Battle for Bonnie McMurray").
After MoDean's II burns down, she becomes a waitress at the Letterkenny Ukrainian Centre, and is often seen there. After MoDean's 3 opens, she works there as a bartender, where her jealousy over Wayne leads her to make inhospitable comments about Marie-Fred("What Could Be So Urgent?").
Bonnie is desired by many in Letterkenny, including Daryl, Dan, and Katy, who barely concealed their interest when all attended a hot tub party at the McMurrays' home. She chose not to get involved with any of them, preferring to play the field ("The Battle for Bonnie McMurray"). Neverthless, all of the Hicks except Wayne are driven wild by her provocative dress ("St. Perfect's Day"). Like Katy, she is the subject of unwanted attention from the citdiots at Ron and Dax's wedding, resolved only after the Hicks fight them in their hotel room ("We Don't Fight at Weddings").
