(spoilers) This episode had the same concept as the others, the take down of one of Amanda's enemies. I found this particular one very interesting. It showed how much she had to go through in her past. I don't know if every episode will have this same concept, that will be a big risk to take in my opinion.
The best friend of Daniel seems to have his own hidden agenda, which is interesting also. To me it looked like he was on his own path of revenge.
I really like the character development. The actors are doing a great job portraying them. They seem genuine and everything just seems to work.
This show is a big surprise to me in a good way, as Terra Nova for example is in a bad way. For some reason it has this X-factor which some other shows are simply missing. You can throw together all of those great concepts, actors, throw huge amounts of money at it but if it doesn't 'mix' well you have nothing. It needs this X-factor, which in my opinion, Revenge has. (for a very small budget)... It just works. Great work.
