Tabula Rasa (Stargate Atlantis)

Was watching the episode the other day, and rediscovered how much I liked it. A really good way to open the episode, especially because for a good portion of the episode you have little to no idea what's going on, and why people are acting the way they do.

Also, is it pathetic that I saw one of the random characters (Lt. SomethingOrOther), and immediately recognized him as Niall Matter? Who you might recognize as Zane Donovan from Eureka. (Is this the first time that my identification of Stargate characters has gone the other direction?) Also, he looks a bit different in this episode. Probably because he has to play the role of a military officer, rather than the Zane character, who is distinctly not military.
