As he observes the scientists work, Nicholas decides to make himself seen.
"No, no and no. You're doing it all wrong." He says, appearing out of thin air near the scientists.
Some of the scientists are reasonably alarmed by the man appearing out of thin air in front of them.
"I'm here to help you. Don't worry about the specifics, just trust me." Nicholas says as he gets to work on fixing the scientists own work, they were having trouble with constructing suitable alloys for more complex robots to operate in hazardous environments, such as space.
Nicholas was quickly moving about the rooms, fixing their work, before long the issues are fixed, several robots have been constructed. After the initial shock wears off, the scientists also begin to work.
After some time, the head of this lab would approach Nicholas.
"Uh, hello. You've kinda showed up out of nowhere and been helping us work like nothing else, do you want a job here? With you on deck we'll reach greater heights than ever before." The head scientist would say.
"Huh? Oh, sure, that'd be nice, I'd also like, you know, a house or something. I won't be here all the time, but I'll hang around working here a good bit." Nicholas responds, still lost in his work.
"That can be arranged." The head scientist replies.
A bit later, Nicholas has found himself a rather modest home in the city, arranged for him by the owners of the lab.
