It was - mmm how to say - weird episode. They fooled me quite long before I realized it all is just a ... they are copies. The idea was genial one, I most say, but - it was not the best storyline. The can have fantastic ideas but the serie needs more than only good idea - it was quite boring, some way. it did not nailed me to the screen nor had much excitement.
The best moment, I think, was when they finally met the real ones, and then had change to talk with each other. I think that was really great element and symbolic. We all would be our best talking partners, especially as they shared the same thoughts.
