Sebastian comments that Alois has been 'playing' with Claude all this time and he never realized it. As he dies, Claude comments that Alois managed to make a 'small ripple' in the long, boring life of a demon, so perhaps Alois's soul was more precious than he thought. Claude asks for his glasses which he has on his pocket.
Sebastian out of kindness to make his last wish come true he took the glasses and handles to him, Sebastian ask if he needs to say his last words, and Claude says " to turn passion into perfidy, falseness into facts and a stray dog into an earl, only __'s butler"; after his last words he died.
