Sam just got out of class. He was heading of to get lunch when someone got out of one of the classes as well. It looked like nothing out of the ordinary. However, in a split second the guy's expression, both with his body language and his face, changed from a normal one to one that seemed to be serious and even a bit in pain. Sam was usually one to ignore others, but he couldn't stand it if someone needed help. He walked towards the guy. "Are you al right?" He asked. He was a bit curious though why this person changed his expression so fast. He didn't see any reason how it could've happened, and if there should be something immediately threatening, then the guy's Neurolinker should've turned on something like an alarm.
