You had shot and killed Ron's father, Pete after he was found out for being abusive and then killed Deanna's husband Reg. Ron heard about what happened and he immediately had his perspective on you change, his infatuation quickly turned to vengeful rage.

You couldn't find it in you to deny the sweet woman anything so you complied and were now standing on the front porch of the Anderson house, hesitating whether to knock or not.
