Oh! Nothing? That's cruel @cryptogee. It would seem that Asimov had recognised something in K-Rox's make up. Why didn't he destroy as he had destroyed the rest?

The Thincast was a lucky ploy. Asimov could have easily ignored the message and go on to destroy K-Rox though. Why is Jemima's messages never complete?

Well the next episode will have some answers, I think. Great story @cryptogee.
