| There are plenty of PADI instructors on the board who would be happy to help you with any specific queries or things that you need to cover in connection with the OW/AOW course.
I would be more concerned if this was happening predive as inexperienced divers can sometimes forget to do full buddy checks. At the end of the dive then I would suggest leave pressurised but off to prevent water entry- some might prefer to leave fully pressurised if disembaking the boat with full kit.
With regards to freeflow, then we would need to know more about the circumstances, kit etc before being able to comment on why a freeflow has taken place. As you know the OW course teaches you how to breathe from a freeflowing regulator second stage - you could bend the hose or shut the gas off to stop the freeflow but these may not be appropriate solutions to the problem when underwater, far better to either continue to breathe the second stage or secure your buddies alternative air source.
Please feel free to Pm if you have any further questions
