The appearance of the Unsubtle in the Armory garage made Oswald chuckle from deep in his chest. "Fuckin' Marcus. I could not be with a better team leader, for the love of all that is good in the world." The professor's interest in the marvel of engineering was quite apparent, and it made quite a bit of sense. How could one look at that thing without experiencing some sense of awe? Even Oswald, as simple as he was, couldn't help but get excited as he thought of how much work and machinery went into the tank sitting in the class. 

The professor's command to show what the students had and were capable of brought Oswald to full attention. He was standing before he even realized, undoing the scabbard that secured his sword at his side, carefully placing the weapon on the workstation in front of him. He also removed the shield from his back, and reached into the small pouch where he carried his dust crystals, pulling a small blue one out along with a small cloth, wrapping the crystal carefully before setting it down. "I don't need to tell you to be careful with that. But I will anyway. It loads into the pommel. Fires out the tip. Should freeze juuuust about anything."
