You were observant. Thats just what you've always been. You notice how people and/or things act differently and when things slip up. That being said, you've noticed something different about Luke, the counsellor that everyone loves and feels comfortable with. You get paranoid, since that is unusual for you to see Luke in that way.
You start watching and following him around when nobody else seemed to notice a change in him. You watched as he trained alone. Luke was taking his anger out on the poor training dummy since he was slashing at it repeatedly with his favorite sword.
Luke had looked furious. Nobody had seem him act like this before, even during regular spars with actual people. Then, Luke stopped. He turned towards the trees that you were hiding behind.*
"You might as well come out now." Luke had suddenly spoken, looking to spot you in the crowd of dark trees.
