Julian had skipped out on most of parents weekend. His mom had explained that she'd seen it all before and didn't need another tour around the school and as such he'd spent most of Sunday chilling in his dorm room. When the explosion went off it rattled all the windows and he could see the smoke from where he was standing. Rushing out of the building, Jules was in full-blown panic mode. He hadn't gone to the talk on the green but that didn't mean his brother and sister didn't end up going!
Rushing past hordes of people, some dusty and coughing he grabbed anyone he recognised. "Where's my brother! Have you seen my sister?" No one was answering, more interested in the location of their own families.
He skidded to a halt at the parking lot, the smoke stinging his eyes, though frustrated tears were welling up, too. Taking out his wand he flicked it irritably, the weak silver of a patronus disappearing before it even reached the floor. Yelling in French on frustration, Julian looked around for someone to help him.
