The Genii at this time were such a great nemesis - I loathe them.
I thought their deception, posing as simple farmers was good. I'm glad so many others mentioned Tyrus' stupidity. No, I will not let rescue the prisoner, it will alert the wraith! I will however shoot several bullets into him.
My favourite line from this episode courtesy of McKay;
"If people could just learn to keep their secret underground hatches locked.."
Tiny little things make all the difference in this series. Shep's ease and confidence when Cowan tells the team to follow him. Shep gets up from the table swiftly to lead, while the others take a more slow and hesitant stand. I love it.
More little things I loved:
Ford without a hat
Rodney + Ford table banter.. "It wasn't a working model."
