Simus and the explosions

A young man in a dark sweater leans over a steaming cauldron, inhaling the rising vapor, while another student watches from the side in a dimly lit classroom filled with shelves of bottles. The scene cuts to a group of students in green and white uniforms, some looking on with concern, then to an older man with a long white beard and wild hair, who appears shocked or distressed, followed by two boys at a desk, one with a smudged face and a wand, and finally a boy with a bandaged eye sitting at a table with a basket of fruit and a goblet.
