Is Molle the only student in this entire school who doesn't have problems with his parents? You have the strict Alexandra who's apparently not above striking her 12 year old child when acting out. You have Tim's parents, who priortise their jobs over their child to such an extent that they're oblivious to his crippling anxiety attacks. And now we see Henry's dad who spends one of the few days he gets to see his son yelling at him over his grades.
If this is indicative of their home lives, then maybe it's a good thing these kids are in boarding school.
