He considered Me's theory on the train. It sounded odd to him, but the technological development of the Imperium had taken a very unusual path. "I am uncertain how a train could make a choice of its own. Do you propose that the train is a thinking machine?" He frowned slightly at this thought. He'd never pictured the ancient thinking machines as transportation devices. The histories were never clear on what they were, other than a problem.
"Ahh, but you are quite right about people and their emotional compulsions. Oh, the things that someone will do in the name of saving someone that they love. There is no line that someone will not cross, with the right motivation." A smile, as he recalled the death of his foremost enemy, and with it, the fall of his enemy's House, ancestral rivals to his own. The smile faltered, however, as he recalled what- or more accurately, who- he'd lost at the same time. Nothing had been the same without his twisted mentat and his devious mind, so beautiful for all its necessary flaws. But, there had been nothing he could have done to prevent it, sparing him the question of what he might have done to have kept him alive. But, perhaps the answer to that question was why he'd never ordered the duplication of a replacement.
But he did not want to dwell on this memory- Me had said something to catch his attention. "So- you are from Earth? It is said that Earth was the birthplace of humanity. You are, then, from a time long before my own. We no longer know where Earth is. Or was- perhaps it no longer exists. We have only the fragmentary records of our ancient ancestors. Stories, some works of art, texts of religion and philosophy. You will need to tell me about Earth."
