Lois suspects Stewie is the one creating all the pee stains around the house, so she decides to potty-train him. When an incident in the supermarket reveals that Brian is the one responsible, he goes to see a therapist. Brian finds out that his love of Lois is causing his accidents, so he decides to confront her.
I am sick of Brian being in love in every damn episode with him.
Can't he start being in love with his own species? Jeez.
Overall, I didn't like this episode that much at all.
