I see that many folks like Blaine very much moreover there are people who feel sorry for him.
For my part I liked the character because it was interesting and new but I felt no sorry for it at all. For me it was hard to think of me as a train and when I was first reading it I couldn't. Now I can.
What did he do what he had done with the people in Lud? Was he lonely? Was he insane? Can a robot be insane at all? Have feelings?

Let's talk about our choo-choo Blain.
