This episode marks the return of my favorite group of people in this series the Genii. They are sometimes not the brightest bunch but this time they manage to outsmart the Atlantis team. Ladon is a great and smart character. His banter with Sheppard in the beginning was funny most of all was what he wanted for the ZPM.
LADON: I need about a hundred machine guns, a couple of dozen grenades and any C4 that you have to spare.
SHEPPARD: Sounds like you're having a party.
This was a very smart script with great twists and made it one of my favorite episodes of the season.
