Nathan had to catch himself, as he almost fell into his new machine prematurely, as he started to get a better grip and pick himself out, his ears titched, he heard a noise, a noise that wasn't from an experiment in his laboratory! 

Slowly he raised his body out of the open hatch in the time machine, than clutching tightly to a wrench in his left hand, and his right hand with all of its fingers close together ready o karate chop, he slowly, and stealthily moved towards the person he know saw, who had made the noise, after letting themselves into his lab no less!

"Freeze!" He shouted in his manly cracking voice, "Who are you?! How did you get in here?! Are you a spy? A rival scientist here to steal my inventions?! Or the worst of all, the dentist dropping in for a random inspection of my mouth?!" He went into the fetal position whilst on his feet for a while as he continued to speak, this time not facing Skye, "Oh I hope it isn't the dentist, they weren't to happy last time I told them I was working on a machine that would clean mouths perfectly and put them out of business." Standing up again, and trying to regain his composure, you pointed his wrench at her, "Speak!"
