Genghis:
i would suggest that rather then recreating the event, you use it instead as an example of why the foundation flying skills matter
My experience is that many recreational pilots accept sloppy flying from themselves. The reality is most of the time it doesn’t matter. However your incident is a perfect example of when near perfect flying could be the difference between a successful outcome or a bad ending.
For example if the airplane is going to climb with a reduced power condition then nailing the pitch attitude and staying coordinated is critical. I would suggest going to the practice area and experimenting. Set a reduced power and show your guy what happens when the ball is half out of the cage and the airspeed is 5 kts too slow.
Similarly the kind of scenario you described also will often require a fairly steep descending turn towards the runway. Again something worth practicing and showing what happens if you do it badly.
