Blood was splattered everywhere on the ground near Lith's table. Everyone present in the cafeteria was currently looking in his direction.
More precisely, they were looking at Ralph in shock. Fighting on the academy grounds wasn't allowed, let alone killing someone. Ralph had violated the rules and messed up big time. This was what was going on in everyone's heads as they looked at this scene in shock.
The staff members who were watching were shocked too. They never thought that Ralph would violate one of the rules of the academy, which stated no fights anywhere on the campus apart from a select few places.
It wasn't even a fight, Ralph straight up killed the guy without warning. Because of their initial shock, the staff members panicked, causing them to forget to actually call the respective authorities for this matter.
