During an activity at a grief seminar, the leader of the group encourages everyone to walk over burning embers with their bare feet. Nobody is injured until the group leader stands over the embers for an extended period of time and ends up burning his feet. His blistered feet are shown in the next scene.
A man in a state of duress allows himself to sink to the bottom of a pool. He is in a sitting position with his eyes wide open, and it appears that he might be committing suicide, although he arrives at work in the next scene and is fine. This may require some explanation if you are watching with younger viewers.
