could it be he had surgery to remove skin cancer or something like that and the black eye just be because it was close to where the surgery spot was? Like I said, it’s just a guess but he’s out in the sun and it wouldn’t be that uncommon to get a spot that has to be removed. I didn’t see him without the sunglasses so I don’t know what the rest of his face/eyes looked like. Maybe a little sensitivity to the bright studio lights? Could be a skiing accident?
