I hated the way Kate knocked on that green door, in this last episode. She urgently wants to get the attention of whoever is inside of that building, so she slaps the door with the palm of her hand.
Which creates very little noise. I don't understand why anyone would knock on a door this way. You're supposed to use your fist when you knock. You produce a much louder knock that way. I know I'm nit-picking; but for some reason, this really bothered me.
I have to agree with the above posters who feel that the spy plot is getting old. Even though, that was the most interesting part of the show in the pilot. They need to have Kate do other things besides deliver packages. Maybe she could sleep with some Russian official, in order to steal some documents. Or they could have her poison an enemy spy; get some blood on her hands. That would definitely liven the show up.
I liked the back story for the pilot that wanted to be an astronaut. I was happy that he punched the head captain. A full blown fight would have been cool, but for now, I'll settle for a punch.
I think they missed a story opportunity with the head captain. Instead of him getting his promotion by talking to some higher-up in an elevator, they should later reveal that he blackmailed a higher-up to get his promotion.
