Jacqueline is a widow who only appears during major family reunions. She has respiratory problems - no doubt from smoking - and only talks when she feels the need to insult someone. She's very old fashioned in her sense of romance, willing to go with whomever courts her, regardless of whether or not she likes them. Deep down, she'd rather be a widow than someone's trophy wife.
Abe fell in love with Jacqueline, though its still unknown how she feels about him. When Abe is about to kiss her, Mr. Burns appears and takes her away. Abe falls into a depression. On the day of Jacqueline and Burns' wedding, Abe interrupts it and runs away with Jacqueline, knowing full well she didn't like him but didn't like Burns either, seeing it as a victory nonetheless.
- Jacqueline is only ever referred to as Mrs. Bouvier by Abe. The fact that neither man ever used her first name might have contributed to her flippant nature.
