Thank you for reviewing! It is indeed an intentional set-up from my side. My feelings about this kind of group session will probably be more obvious to you in the next chapter (through Harry). My point is to show that sometimes, in response to a traumatic event, people (including responsible adults) don’t think clearly and - despite having good intentions - disregard the side-effects of their means to get to their goal, thus doing more damage than good. 

I can well imagine that in the wake of the war, and in response to first the attack on Hogwarts and then the suicide, worried parents, the school board and the Ministry exact of the headmaster that something is done. Their worry is understandable, their demand is reasonable. But when it is not accompanied by the necessary means (only one healer, no Swallowscope), they miss the mark. 

In this situation, Healer Schufflert should have protested (or Snape, but maybe he did?). She probably doesn’t realise that her task is impossible. She’s young, can’t be very experienced, in fact, and - I agree with you - her arrangement for those group sessions is abysmal. 

Healer Schufflert might just be one of those slightly megalomaniac therapists that unfortunately exist, also in the magical world (among extremely considerate and professional ones, of course). She’s probably honoured by the task and eager, perhaps, to prove herself, to a point where she loses sight of the pupils best interests…
