I didn't see it either. But Sirius's actual  presence in the stands
is an ESE!Lupin clue. According to the theory, Lupin summoned 
the Dementors when he spotted Sirius from the DADA office. 

 I also saw Lupin in Trelawney's crystal when Harry returned it. 
This would of course preserve the crystal/orb clue that 
was lost when the Boggart became unequivocally the full moon.  
I recognized Lupin in the crystal  by his mustache but some 
people seem to think it was Sirius or Voldemort. Am I mistaken? 
Did anyone else catch that?
