Maybe he shouldn't have been risking anyone else over one man. We had a chance to pull those guys out of there, which as far as I remember is what you all wanted. On man wasn't going to break the mission. What happened to the space military code or whatever it is you guys live by?

You're just mad that you couldn't do anything out there yourself.
