After everything that happened that day and night, Scorpius isn't surprised that Albus won't even look at him, but it doesn't make it any less painful. He probably feels guilty and gives him the cold shoulder. Scorpius has been through this more times than he cares to admit, so he just lets his chin drop to his knees instead of complaining. There would be no point in pestering him, and they would just end up arguing again.
