I have to ask why the kid was mask clearing in the quarry to begin with. I would assume if he had problems there then he had problems in the pool. Should have never been in the quarry in the first place. Just my opinion.
Granted, I've been drinking, but I don't think the question was, "Should the kid be in the quarry?"
If you've been diving for any period of time, you're going to have a need to clear your mask. The question was, "Should his buddy pull him back down?"
