Here's a chap undergoing therapy. there's a tank of water set in front of him, with a glass screen, and a spout of water upon which there's a table tennis ball! Now I'm not going to ever try and put an interpretation on what this form of therapy is. It's inexplicable as to why a hospital patient should be given the Prisoner's own suit of clothes to wear? Could it have been a warning to the Prisoner, that perhaps he himself might have to be put through some kind of aversion therapy? Or then again, perhaps it doesn't mean anything at all, just being something the viewer has to accept. But then again, McGoohan had a deep mind, I cannot think that he'd have a hospital patient dressed in the Prisoner's own clothes simply for visual effect. Ah, that's more like it, with the Prisoner McGoohan was messing with our minds!
Be seeing you
