What do you do when donating to a panicked diver who initiates a buoyant ascent?

This might be hard to believe but I dealt with a panicked buddy on the first dive of my life. My wife and I took a class with some of her work friends, including her boss (the OOG diver). At the end of the course, we are in the lovely (sarcasm) St-Lawrence river for the final in water 33ft tests. Once completed, we are all certified and the instructor decides to bring us for a quick tour around the area. We're at the bottom, no more than a minute under way and I feel a tug on my fin. I turn and he's looking at me with huge eyes and no reg in his mouth. I completely forgot about my spare reg, I grabbed his shoulder strap and put my reg in his mouth. Thankfully he didn't bolt, we just slowly ascended and shared the one reg back and forth. He later explained that he couldn't get any air from his reg, but I don't see how that could be.

Probably his valve was not fully open. Did your wife get a raise?
