Someone touched my plant while I was away and removed the farina. I am enraged.

I got this plant 5 days ago from my social worker and it was almost completely untouched, it looked perfect. While I was at the dorm some kids from the orphanage did this. And I know that they were just curious cuz I have a lot of stuff in my room and I'm new here but DID THEY REALLY HAVE TO DO THIS???

I wanted to confront them but whoever did it will most likely not admit to it and I don't think that they will take it seriously.

Bruh. And now it will not grow back. And it is bad for the plant. Is there a way to help the plant?
