Sure, I bet Mayhem is a bit of a druggy and he is clearly disturbed. But..., I don't see anything that would be unexpected from him at all. His eyes were clear and he was attentive, so that kinda does away with the thought that he was high. Granted, I think he took the whole staying in character thing a bit far, but when has Mayhem not taken things too far? I really don't understand what all this, "he's mental,", "he's a druggie,", "he needs to lay off," talk is. All of that may be true, but what I saw was just Mayhem being Mayhem.
