If people saw him, why didn't they ask? Certainly Victor knows what his situation is.
Edit: It is beyond me why people post questions and conjecture and can't have the decency to talk to someone face-to-face. The guy is 1000s of miles from his family; talking to him, asking him what's going on, and conveying support, regardless of the situation, might be of some help to him. When I talk with him, he comes across as a great, caring, young man. I hope he finds it within himself to realize he has an issue and to resolve it.
