This was one of the better episodes in a while. It was a nice introductory course to people who have never been exposed to the hacker world. I am surprised they didn't bring in any comedic guest stars in this episode, which has been a recent Numb3rs trend, but I am glad they did. This episode brought back the danger that makes the show exciting. I enjoyed watching the firefight scenes at the FBI building and at the beach. The shot to the neck looked painful. I also feel bad for the valet who got it in the beginning of the episode. I hope they bring Augie back as Nikki's love interest because her character can use more development. I also really thought it was funny that Amita got the invite from Kathie since in Flashforward, the character the actress plays is also a lesbian.
