Welcome To Plathville season 5 has seen Moriah Plath becoming more and more like her mother Kim Plath, especially with the pair sharing a deeply selfish nature. As Welcome To Plathville season 5 has continued on, the Plath's children have been shown dealing with their parents split along with the issues they've been dealing with throughout the last several years. Moriah, who was once close with her sister-in-law Olivia Plath, has been changing throughout her time on the series, but in recent years she's come to resemble her mother Kim more than in the past. Kim, who many find problematic, may not be the best role model for her daughter.
