There is so much to be said about Stana Katic’s performance in this episode and how she portrayed the subtle transition from blissfully happy to concerned, to playful, to incredibly jealous, then seriously pissed off and incredibly vulnerable. This episode was a prime example of her amazing ability to convey her character’s emotions with just a facial expression. The end scene alone was probably the best example of how she manages to go from one emotion to another in a flash. It was so incredibly amazing to watch.
