I'd wonder why they sent some nerd (Me) into the field with Sam Fisher in Chaos Theory....
Then possibly try and think up some dark under-toned and intimidating things to say as I TRY to sneak up on guards while avoiding UAVs....
Maybe make a few passes at Grim.....
Grim: So you're going to want to take the path on your left.
Me: So Grim, after this you want to meet up and get to know each others' hardware better?
Sam: Son, will you stop thinking with your lower head for one moment?
Me: Sam, I'm able to use both heads at once. Could you at least focus on OUR mission Sam, and not my communication with Grim? Bloody perv.
