Congratulations, you have made the logical choice.

You bow and say, 'May I join you in your pit, Roy? I believe I have formulated a plan.'

'Please to do so,' says Roy.

You lower yourself from the edge of the pit and drop down into the water with a splash.

'As fortune has it, I happen to have brought a roll of clingfilm or so on this adventure,' you say. 'My plan involves it.'

Behind his trademark dark glasses Roy raises an eyebrow. 'I cannot possibly imagine how you intend to employ it.'

'It is my proposal, Roy, to wrap you in clingfilm, thereby protecting you from the ravages of the water.'

'Such a good idea has the irresistible force of destiny itself,' says Roy. 'Proceed to implement it.'

'At once.'

I start from the feet and work my way up. That is, you do, for you are the hero. It is hard to wrap his feet when they are underwater so you have Roy stand on one leg at a time and raise the other out of the water and wrap them individually. You take a moment to deplore the sadly waterlogged condition of his shoes. When you reach the waist which is above the waterline you proceed to wrap normally, but you do not do it very tight, but rather in a baggy and loose-fitting way, for reasons which will soon become apparent, but completely watertight. Soon, Roy Orbison is completely waterproofed in clingfilm. Your eyes roll right around in your head like fruit-machine reels.

'You are completely wrapped in glub glub,' you say, for by this point the rising water has reached your mouth. Standing on tiptoe you strain up and take a last gulp of air and then wait for your plan to proceed.

As you have taken great care to trap lots of air bubbles inside Roy's clingfilm coating he has no difficulty in breathing. More, they naturally float him to the surface of the water and holding on you are pulled up the pit with him. As the water fills the room the two of you float up to the skylight! It is made of glass behind wide-set iron bars. You smash the glass of it with your fist, taking care to wrap your hand in your coat first so that you do not cut yourself, then wriggle through the bars of it and are free!

Quickly you pull Roy through after you. You collapse to the floor of a torch-lit corridor above, taking great gulps of air and admiring your work. You have wrapped Roy in clingfilm! And of course saved his life.

With a start you remember that Roy's clingfilm cocoon is airtight.

Do you:

Release him immediately?
Leave him wrapped in shimmery translucent loveliness for a minute, but make topical smalltalk so as not to make things unpleasant for him?
