True. If Barty Crouch Jr. was impersonating Moody at this point, he was probably doing this just to inflict as much harm as he could on Harry. If he wasn’t being impersonated at this point in time, then Moody was just being his usual “CONSTANT VIGILANCE” self. There’s most likely a reason everyone calls him Moody.
