This is a list of Sims who are only mentioned or have very small roles in Lifesimmer's The Sims videos or are otherwise not eligible for their own article or infobox.
Guthrie: Leon Guthrie is from The Sims 3: Generations LP. He was the short-term Boyfriend of Tori Dunbar during her separation from Jai. The only evidence of their relationship can be seen when Lifesimmer is scrolling through the party planner in Part 45: Farewell Fendersons, where he is shown as Tori's Boyfriend.
Gwydd: Lang Gwydd is from The Sims 3: Ambitions LP. He makes a notable appearance in Part 16: Stina Saturdays, when caught kissing his then-roommate Justin Kayes, who was meant to be on a date with Porsha Doran at the time.
Lambert: Adam Lambert, Sadie Mason's rebound boyfriend in The Sims 3: Showtime LP after she was dumped by Trey Doran. He is seen in Part 24: Tatted Up, when on a date with Sadie in the park, sporting an unimpressed expression while Sadie gazes fondly at him. Lifesimmer originally mistook him for Rich Richmond; she dubbed him Adam Lambert for his likeness to the singer. Meanwhile, he is actually Wylie Luck, an Acrobat from Starlight Shores.
Lamar: Nora Lamar, Isaac Santiago's prom night fling in The Sims 3: Generations LP (Season 2). Lifesimmer is amused and dubs Nora his "little girlfriend". However, Nora is only relevant in Part 21: Bowling & Comics; Isaac appears to lose interest in her after that.
Mayor: Mr and Mrs Mayor, Kylie and Kayden Mayor's parents. They do not appear in-game or on the family tree. In Part 1 of The Sims 3: Island Paradise LP, Lifesimmer mentioned that their parents were military generals who traveled all around the world. Kayden and Kylie became estranged from them and never again established communication after moving to Isla Paradiso; as their kids are now Elders, it can be assumed that Mr and Mrs Mayor are dead.
McWilliams: Eva McWilliams, the guardian of the original "New Kids on the Block". She was a Young Adult or Adult Female whom appeared in Part 19 of The Sims 3: Generations LP. Had she continued to appear in the series, Eva would now be dead, because the Teens she cared for have reached Elder status.
Santiago: Mrs Santiago, Zane Santiago's mother. She does not appear on the family tree and is never seen throughout the course of The Sims 3: Generations LP. Lifesimmer divulges only that Julian had to raise Zane alone, meaning that she could have died, divorced Julian or abandoned her family. Zane probably inherited his white-blond hair from her. Another possibility regarding Mrs Santiago is that she was a Teen mother, as Julian himself was only a Young Adult parent to Teenage Zane, which is rare in normal game-play. Because Zane is now an Elder, Mrs Santiago would be dead if she had appeared in the LP.
Talon: Tina Talon from The Sims 3: Late Night LP. She is the daughter of Dedrick Lofton and Jessica Talon. Jessica was Dedrick's "baby mama" in a way and she gave birth to Tina, though Dedrick never met her and only called her once, when she was a teen. She is a vampire like her parents and has the Insane, Virtuoso, Loves the Outdoors, and Loves the Heat traits. After she aged up to a teen, Dedrick had a wish to teach her to drive despite the two never interacting and being strangers.
Brandt Talon is the second child of Dedrick Lofton and Jessica Talon. He is also a vampire and significantly younger than his sister Tina (she was a teen when he was born). He is a loner and a light sleeper.
VVest: Ginny Vest, an Elderly Townie-turned-temporary character in The Sims 3: Showtime LP, appearing only in Part 23: Ginny. She was accidentally ensorceled by the Genie Cindy Cromwell, hence becoming playable for 4 hours. Lifesimmer, unsure of how to handle the situation, had to research the longevity of Cindy's power over Ginny and, having discovered the 4 hour time limit, sent Ginny on an unsociable rampage for the night. Ginny met a Sim named Camille Van Guiel, and proceeded to harass and attack her until she could declare Camille her Enemy. Lifesimmer jokingly stated that Ginny was her "all-time favorite Sim", and pronounced her name as "Guinea". Ginny was freed by the end of the night and never seen again.
Winchester: Odessa Winchester, the woman with whom Levi Moon has an affair in The Sims 3: Midnight Hollow LP. The couple would go on morbid dates to the Ghastly Graveyard or Somber Beach, partaking in such activities as touring the mausoleum. If Levi wasn't with Odessa, he was talking to her on the phone. The affair continues until they are caught by Levi's wife, Abigail - Levi and Abigail then divorce, and Levi chooses to be with Odessa.
York: Mr York, the father of Sabrina and Valentina and the apparent husband of Yolanda York in The Sims 4: Get Together LP. Due to the fact that Yolanda relocated to Windenburg without him, the most likely explanation behind the absence of Mr York is that he is separated, but not officially divorced, from Yolanda. Mr York does not appear on the York sisters' family tree or on their relationship panels.
