Forensic Science
You scale the pipe up to the highest level and find a lady waiting for you. She beckons to you and you come closer warily. "Shhh, there isn't much time. I have the cure for your son, take it and go before he dies and I am found out. Go now" You grab the cure from the lady's outstretched hand and quickly climb back down the pipe and into the waiting cab. As soon as you get back home you run through the house and give the cure to your son just in time. As your son slowly gets better you wonder about the mysterious lady and her motives. Why did she do it? The questions circle around you, haunting you forevermore.
