He could've guessed, but that's not the same as knowing, and he's never seen any indication that Cooper had a hate for them that ran so deep.

It's funny though, Cooper's opinion of him seems to be so different to how Eames sees himself that it might as well be a totally different person. He'd probably laugh if he'd said it out loud.

By the time Cooper returns, Eames is helping himself to a second glass of scotch and he frowns a little at the question. "Like I said, I wanted to understand your position," he answers simply. Cooper's a new face on the Council, a relative unknown quality. Eames had foolishly thought the man was smarter than this; he won't make that mistake again.
