Doc and Mac finally came out of the office to greet the arrivals.

Mac was a quiet guy and always let Doc do the talking.

"Welcome to the Hidden Laboratory. I am Professor Gustov but you may call me Doc. My colleague is Micheal Van Naze. He prefers to be called and will only answer to Mac. Now that you know who we are, we would like to know who you are. Then we shall talk about our experiment. Who would like to go first?"
