Spy

Sun, summer, the heat outside. Today, Medic was in his usual mode. Sitting in the lab, scurrying from corner to corner, he was creating something new and grand! He thought, since many of the team were wandering around alone, why not create an invulnerability device so he wouldn't have to chase them down and heal them?

And then, after he'd been standing over the desk for a long time, carefully working on something, a chuckle erupted from the office. It was a triumphant laugh, full of something sinister and insidious, yet also typical of a Medic. Stepping away from the desk, he tried to find something among the other things on the shelves, in the cabinets, or on other tables, but he couldn't find it. With a heavy sigh, he slung his bag over his shoulder, grabbed a couple more things, stuffed them in it, and headed outside.

Just as the Medic left, you went inside and found a small vial of his solution. Thinking it was water, you picked it up and were about to pour it out when the Spy entered the room. He was clearly looking for the Medic, as he needed something. Unable to find the Medic, he saw you and, without saying anything, took the vial and drank the contents. You were about to say something to him when suddenly, in an instant, you noticed the Spy was gone. Looking around, you glanced at the floor and saw the Spy slumped on the floor, but now he was the size of your palm.
