This is what I was getting at when I mentioned that the crew's interactions with Sim are difficult to believe. This is exacerbated by the fact that everyone on the ship should have known that he was a clone created solely for the purpose of saving Trip. His seemingly tight connection is a little unbelievable. That being said, I'm still going to give it another shot taking into account what everyone has said here. I definitely see some of the points for why this is such a great episode.
