Even with the difference in their ages and social standing, Olivia knew Samuel was perfect for her from the instant they met. It was easy to ignore the taunts that she only married Samuel for his Goth family fortune – that was only one of the reasons! Olivia didn’t even mind that Samuel’s niece accompanied them to their new home in Moonlight Falls. Life became much harder when Olivia lost Samuel to a rogue magic jelly bean. After all, what kind of relationship could she have with a ghost? In her despondence, she accidentally shorted out the stereo and became a ghost herself! Olivia has since stayed away from most electronics, and doesn’t really like all the new gadgets Helen keeps bringing into the house.
When Samuel died while eating his favorite candies, Olivia was distraught. Distracted with her grief, Olivia accidentally electrocuted herself and set fire to her house and ultimately caused Frida's death as well.
The difference in age between Olivia and Samuel Goth may be an allusion to the possible marriage between Mortimer Goth and Dina Caliente, who are in the elder and adult stages respectively in The Sims 2 (with the young adult age span only being acceptable in University neighborhoods).
