Adolf payed no attention to the fight in the courtyard for the simple reason that it wasn't interesting. He just passed it by, disregarding the event as he wandered through the courtyard minding his own business, singing to himself as he went.

"Auf der Heide blüht ein kleines Blümelein

Und das heißt: Erika"

He continued on through the courtyard but stopped short off to the side, struck by that feeling Naught gives him. He glanced up at the school's towers, looking at them for a moment before smirking and continuing on his way. 

"Heiß von hunderttausend kleinen Bienelein

Wird umschwärmt 

Erika!"
