Mary-Sue Pleasant

Mary-Sue Pleasant is a pre-made Pleasantview Sim who lives in the Pleasant house with her husband, Daniel Pleasant, and twin daughters, Angela Pleasant and Lilith Pleasant. She was adopted by Coral Oldie and Herb Oldie as a toddler and has slightly Asian features. It isn't confirmed by Maxis, but her name refers to a pejorative term used to describe a fictional character.

Life in The Sims 2
She is a bit of a workaholic, and seems too immersed in her job in the Politics career track to notice all the problems at her home - including that her husband is having an affair with the maid, Kaylynn Langerak. The Maxis plots show that their lives look perfect on the outside, but it's not all flowers and smiles. She does seem to have a little obsession with perfection, which relates again to the name she was given.

When the Pleasant Family is first played, Maxis has arranged everything into a recipe for disaster, somehow like when the Goth Family is first played too. While Mary-Sue is at work and the twins are at school, the maid Daniel has an affair with, Kaylynn Langerak, comes to the house to clean up. Like every service NPC that is friends with someone of the household, she asks if he wants to hang out after work.

What usually happens is that, following Daniel's wishes to WooHoo with Kaylynn, Mary-Sue gets a chance card from work, and the player, knowing no tricks and being relatively new to the game, invariably chooses the wrong answer. As a result, Mary-Sue comes home right away, in the midst of Daniel's sneaky affair...
