Glad he is okay. Ensure he keeps up with councselling mate. It's very important to be able to work through the situation and to address what actually happened. The worst thing he can do is to ignore it and have the incident rear it's ugly head in a few years time, when he's not prepared to deal with it on a mental level. It's the type of scenario that, flashbacks can get triggered by almost any situation. If he deals with it now, when those memorys occur, he will be able to handle the situation without hopefully adversly affecting his life.
