In Redemption Song, she attends the Friendship Club retreat. When Jay Hogart arrives to pick up Spinner, he decides to stay instead of driving Spinner back, so that he could try and sleep with Melinda. She falls for Jay's blatant lies, causing Darcy to describe her as "not the sharpest tool in the shed."
Jay: "My dad just couldn't take it anymore, so he just took off on his hog." Melinda: "And your mom, is she okay?" Jay: "Well, I helped her through her painkiller addiction, but, once she was in drug rehab, it was like, I was addicted, addicted to helping people." Melinda: "Really?" Jay: "Yeah." Melinda: "So, that's why you left school?" Jay: "And, headed down to South America, yes to the mountains of Ecuador. I built a church, and a one room school, and a well. It just, it felt so good, you know?" - Redemption Song
