Olivia Plath has gone through drastic changes since Welcome to Plathville season 1. Three seasons later, Olivia's relationship with her in-laws has gotten much more strained, as has her relationship with her husband, Ethan Plath. She has also grown a lot, as she has started her own successful business and started living in a city she feels more comfortable in.

When fans first met Olivia on Welcome to Plathville season 1, she and Ethan were still in their all smiles and giggly honeymoon phase. She was enamored by all of the things Ethan had never experienced growing up, like any type of soda or Christmas movie, to name a few. Though Olivia's relationship with Ethan's parents, Barry and Kim Plath, was rocky at times due to her being seen as a bad influence, they were able to be cordial in the earlier seasons of the show.

However, her relationship with his parents only soured further on Welcome to Plathville, and she was not allowed to see his younger brothers and sisters without a chaperone anymore.

She also built a strong sisterhood with her sister-in-law, Moriah Plath, and the two even live together now with Ethan.

Olivia grew up in a small town like Ethan, but she had dreams of traveling the world. She has been able to travel all around the country and has started her own wedding photography business that allows her to constantly travel. Welcome to Plathville fans saw Olivia outgrow the small town of Cairo and were thrilled when she decided to move to Tampa, Florida, for a big-city feel. She has matured over three seasons of the show, with some people calling her the only voice of reason, while others think she has become more like Kim.

Over the course of Welcome to Plathville, Olivia's relationship with Ethan has changed greatly. They were extremely happy in the beginning of the series but eventually discovered how different their personalities really are. Ethan wanted to stay in rural Georgia and Olivia wanted to leave their bad memories behind for a city. At some point, they started to argue constantly, and Welcome to Plathville fans were heartbroken when they separated, with Olivia staying at a friend's house for awhile. They are continuing to work on their marriage and, though Olivia has divided fans, they hope she and Ethan are able to work through their marriage troubles on the show.
