"Can I ask a question?" Jon asked.
"Yes. What is it?"
"Why do you look like a woman? Is that what you really look like or did my mind make you like that?"
"This is what I really look like. The master made us all this way."
"Master?"
"Yes," 749 replied. "He created us for his pleasure."
Then Jon got it. This master alien guy created a bunch of sex-bots to give him pleasure. But why was he after Jon's stone? Maybe he could get some useful information out of 749 that could help Jon out of this mess. Of course, Jon really only needed to wait until the 24 hours were over and the aliens would disappear, but what if this master guy or Sarah or Karyn wished for something before then?
