Sydney Bristow: Are you insane? Calling me in here for a social event? SD-6 has a division whose sole responsibility it is to track their agents and report back suspect activity. "Your girl" is risking her life, and you yours, every time we lay eyes on each other. So, do me a favor: don't be so friendly.
C.I.A. Agent Seth Lambert: I-I just love your spirit.

Not really equal to previous two episodes
26 May 2016 | by (Belgrade, Serbia) – See all my reviews

I am objective enough to admit that there have been many episodes that were better than this one, and even though it doesn't have the top-to-bottom awesomeness of the first two episodes, it is not a bad one.

The episode picks up right after the previous cliffhanger and after a brief scene of fighting, it becomes even more badass when it intercuts between her escape and a later conversation she has with her Professor, who chastises her about her focus during his class.

Back in LA, we are introduced to two new characters that will be leading plot further into development: 1. Milo Rambaldi (mad scientist that Sloane has a crush on) 2. Anna Espinsoa (K-Directorate spy, beats Sydney in everything)

What stopped me from giving this episode 6 stars is, probably, the best mission/fighting scene in the first season. The whole mission in Spain was this massive ball of brain power and physical abilities that you couldn't help but enjoy. And after that, it goes same as every week: new plot, Jack saves the day and a cliffhanger superior to the previous one.

Like I said before, this was not a bad ep, just far away from being equal to the previous two. In my honest opinion, it would be far better if they didn't try to balance that much between Syd's "real life" and the spy one (I mean, yes, put them both in but not always 50/50, let one dominate another for some period of time) .
