AVClub: Ah, thank goodness, a Roslin episode. We get flashbacks, we get drama, we get life-or-death. Although I’m still not entirely sure we get her. One thing I’ve been noticing this rewatch is how Roslin is the most opaque of the show’s major characters, at least partly by design. One of Mary McDonnell’s signature moves as an actor is her smile; it’s a look that you immediately recognize but that’s almost impossible to pin down completely. Whenever things don’t go her way, whenever someone says something she doesn’t agree with, she’ll smile—polite, slightly pained, and depending on the context, either heartbreaking or hilarious. It gives you a sense of just how smart she is, and just how determined.
