Have you ever been hanging out with someone, then they have to take a call, and they start looking increasingly nervous and awkward throughout the whole conversation, half of which you can't hear. As soon as the conversation is over, the other person, pale in the face and looking like he's on his way to the electric chair, tells you that 'he has to go', and that he's 'sorry to cut this short', then bolts in the other direction? It's kinda like that, but with robots and fratricide.
