Persons Unknown. Joe is a mole, right? When I recalled events of the pilot episode, I realized it was obvious all along. No one could find a key that fast. -Glucharina
Fridge Logic: Moira accuses McNair of killing people for money. While this is supposed to sound like he is some sort of mercenary, assassin, or what have you, this seemingly ignore the fact that he's a professional soldier. IE someone who is paid to be in a soldier which usually involves killing people.
In that same episode, Erika tells Bill that she knows about his history of blackmail and promises not to tell the others in exchange for a favor later. This might have worked if Moira hadn't been sitting on the exact opposite side of the bed as them, making it VERY likely that she overheard everything they were saying.
