In a low and calm voice he spoke, "A coffee would be nice..." Nathan couldn't help it as a genuine smile appeared on his face. Before he knew it, Sky was gone, which gave him time to think out this whole situation, and continue the needed work on his time machine. Jumping back into the hole that he crawled out of, he managed to squirm his entire body inside between the outer casing and the important mechanics. 

And hour later, he had worked his way out of the machine, but found a new problem, he had made a new hole which he had crawled out of. "No wonder people didn't do time travel, the machines themselves constantly want to change forms." He looked at it from on top of it, framing it with his hands and staring with one eye, his thoughts would have to wait though as he heard Sky call out. Nathan raised his head from looking straight down to were she was standing, "She really did bring coffee..." With cat like reflexes, he jumped down from the machine, skillfully landing on his two feet, only to fall backwards on his butt a second afterwards. 

"Welcome back," He took the coffee in both of his hands, holding it carefully and sipped it initially, then downing the whole cup. "Ahhh, that was good and needed." He changed again to an animated pose this time, changing where his arms where with almost every other word, "Miss Sky, Pursuer of Science! I the great Nathan Burnoise, will put you under a probation of time to se if it is truly learning that you are after, and, if you shall succeed, I will teach you the things thought to only be in science fiction novels!"
