In the fourth episode of Series 7, Kelly has sex with Paddy in exchange for money, after Paddy found it hard to "pull" on a night out with his sons. Paddy wanted to hurt Shane since he felt Shane had not been there for him. Paddy and Kelly kept their encounter a secret, but during a mass wedding scam, Shane proposed to Kelly. Kelly turned him down several times, even ending their relationship, because she could not marry him while living a lie. Shane told her he would forgive her sleeping with anyone, at which point she and a guilty Paddy made eye contact. Shane was devastated to learn the truth, but forgave Kelly, and they married in a civil ceremony at the Jockey.
