Beginner ski lesson down a Black Diamond

I occasionally see skiers skiing terrain that is beyond their abilities. Some of those skiers I will see later being brought down in the Ski Patrol's sled. This day was a frozen hard pack day. Off the groomers was torture for the most experience skier. As I was heading up the chair for my first run I noticed a skier going down The Face, a Black Diamond run. I thought to myself "this should be interesting. As I got closer I could see that this skier was way out of his element. I didn't want to see someone get hurt and then see them get put on a Ski Patrol sled to be taken off the mountain when I ride up the chair again. So I had to help this person get safely down The Face.
