I'd completely forgotten that a Doctor had already died, actually. But, like I said, the Cylon Commander never stated what roles were in play, or how many of each role there are. So, I'm willing to accept that you're a Doctor. But, you protecting Roslin doesn't necessarily mean anything: you could have protected them without them being targeted. Unless you're saying that you were told by the Cylon Commander that the person you protected was targeted?
