S2E6 Mice

Tracey is appalled by the mess in Sharon's bedroom, and her shock deepens when she realizes that Sharon's lack of cleanliness has infiltrated the entire house, especially when she spots mice. After tidying up and purchasing poison, Sharon decides to get a cat, but it fails to resolve the issue. Ultimately, Sharon calls in pest control, only to learn that the exterminator has been dealing with a significant mouse problem at Dorien's place, revealing that the infestation originated from there.
