This episode presented some fairly good ethical issues on cloning. The drama invoke much emotions on this issue. One might say that this was somewhat a provocative episode. 
For Archer and his Xindi quest, he was confronted with a real serious moral dilemma. How far will he go to complete this mission? One thing is for certain. Archer is determined to do anything to stop the Xindi from destroying earth. 

Watching the clone grow was good. One could feel there was an actually real person developing and maturing over the course of the scenes. 

Contemporary issues about cloning were addressed in just the right sci-fi way. Many of us viewers can relate to the way that current emerging laws on cloning by legislators are developing. From what I've seen on some of these laws, I think that politicians have been watching too much science fiction.

I think that they could have had a better ending. It could have used a bit more unexpected twist and surprise to the plot. Overall a good episode.
