I can't do anything about the zero upvote value, it is too late for that, but I am not going to leave this episode without even one comment.
At first, I thought of Sam as a dilettante, but I am starting to like him. Even for a normal human, he is a good person. Considering where he comes from, he must be a rare creature. I do not think he is good because of his upbringing as a Terran, it must be something inate.
Am I sensing him correctly?
Yes, I think so. I was aiming at a kind of ambiguous character with Sam--he had the power to be evil, but he's chosen to be good.
