Lyndsay is very similar to Tetra the pirate from The Legend of Zelda: The Wind Waker and The Legend of Zelda: Phantom Hourglass, as they both share some facial and body features, and they have similar, adventure-loving personalities.
When you talk to Lyndsay after the storyline at the Royal Academy in MySims Kingdom, she refers to Rosalyn P. Marshall's job as mayor in MySims when she says "...she can run a whole town, I bet!"
In MySims Agents, Lyndsay has all the interests except Paranormal.
Lyndsay's MySims Agents concept artwork shows her with a lighter skin color and blue eyes, though in all the other games she appears in, she has had dark skin and green eyes.
In the DS version of MySims Agents, she says that her favourite color is red.
If you send Lyndsay on Liberty's mission in MySims Agents she will quote, "Snakes. Why did it have to be snakes?", which is from the movie Indiana Jones: Raiders of the Lost Ark
In MySims Kingdom, when you are doing a scroll that is also a task, she'll give you a hint.
There is a typo in her MySims SkyHeroes dialogue after you complete Diversionary Tactics, as she says "These Fortune Hunters really creep my out!" instead of "really creep me out!"
In MySims Kingdom, on the Royal Academy Island, when Buddy goes to ask Rosalyn to dance, Lyndsay will say, "Buddy, doesn't care to ask me to dance!" which means she could have a crush on him.
In The Sims 4, Lyndsay appears as one of the MySims trophies that can be collected by players. She is an uncommon trophy and described as: "With an insatiable thirst for adventure, Lyndsay always keeps one eye on the horizon. Her contagious energy often sees her friends swept up in her latest quest. May have had a thing for Buddy at some point??"
In The Sims 4, there is an electronic device called "Lyn-Z" which is a reference towards Lyndsay.
