When "the real Seymour Skinner" arrives in Springfield, Agnes ends up rejecting him in part because he stands up to her, but also because unlike Skinner/Tamzarian, her biological son is independent and does not need her anymore, while Skinner immediately reverts to a good-for-nothing without her.
Agnes' first name was revealed in the seventh season episode "Bart the Fink".
She debuts in "$pringfield", where it is explained she was captured from the wild by Ernst and Gunter. Arnie Pye (voiced by Dan Castellaneta) is a disgruntled, somewhat eccentric helicopter traffic reporter for Springfield's KBBL-TV (Channel 6).
She reappears in "Viva Ned Flanders", performing in Las Vegas. He dislikes pompous anchorman Kent Brockman, with whom he often gets into arguments on the air.
In "Boy Meets Curl", it is revealed that Agnes' resentment towards Seymour may have begun even before her son was born – during the 1952 Summer Olympics in Helsinki, Agnes competed in the pole vaulting event while 9-months pregnant.
