This Town ain't Big Enough for the Both of Us[]

Leanne shows up to the hospital in a rush to stop the kidney transplant between her son Sean and her ex-husband Dean, accusing Dean of selfishly using Sean after being a bad father to him for years. This leads Dean to want to cancel the surgery because he does not want to cause a rift between his son and his mother. After a conversation with Maggie Lockwood about her divorce from her husband Ben, Leanne decides to let it go and, unable to summon the courage to face her family, leaves the hospital without saying goodbye to her ex-husband or son.
