I'm not allowed to move Nat along a bit (sorry, it seems like I've fallen quite behind) by controlling the infected marine, right? 
By controlling I mean, describing that he is circling the room. Or that he is watching the door. Or whatever. I don't mean making him drop his gun and keel over out of no where so I can save my own ass. 

I just don't want to have to wait for Frengo for each action I have to make to get Nat's ass out of there xD
