Eliza is married to Bob Pancakes, but the family biography implies that their marriage is an unhappy one. Contrary towards this, they have the same starting relationship as other married couples when actually played, though their trait conflicts may cause problems later on. Eliza and Bob have a son called Iggy Pancakes, who was uploaded into gallery shortly after toddlers update.
Eliza is a Young Adult, 20 days away from becoming an Adult. She has the Fortune - Mansion Baron aspiration, and is unemployed at the start of the game. She is very close to completing the first level of her aspiration, and buying one or two more artworks for the house should get her to the next stage. Her house features both a painting easel and a sculpting table, and she will often roll wants to use these objects at the start of the game, perhaps implying that she hopes to be a self-employed artist; however, she has no skills yet on either object, and it may take some time before her products become profitable, meaning it may be better to get her a traditional job, at least at first. She has three points in the fitness skill.
Eliza may be based partially on Betty Newbie, as both are named from diminutives of Elizabeth and are married to men named Bob. Furthermore, Eliza's hairstyle is very similar to Betty's in The Sims 3, while her athletic pursuits are reminiscent of Betty's in The Sims (console).
She appears alongside her husband in the official Stay Weirder trailer for The Sims 4, where she is shown nagging Bob, who is described as "the least interesting Sim in the world".
