I would have voted Scar was most freaked out that WO drove that long to meet Pete, Scar just can't grasp the length us fans will go for free stuff
Samantha's a stranger to this variety of madness...Pete's clearly not. Therefore, B.
However, wildeoscar's escapades were most definitely the more fear-inducing for a normal audience. Thank goodness nobody here can claim that title.
This was my first thought as well. I just feel bad for wildoscar because he will be limited to a very small area of the ship in order to comply with Walter's restraining order.
