When it becomes clear that Pryce is threatening to walk Minkowski out of an airlock in Ep57 The Devil's Plaything, Eiffel says No for three lines in a row. The first of these lines is a low Oh no of horrified realisation. The third is a defiant shout against the idea that he'd surrender. But nowadays it's the second of these lines that gets me the most: a No that's soft, understated, almost breathed, not addressed to Minkowski or Pryce, just a word which escapes him as the full reality of what might happen sinks in. It's quiet enough that it'd be easy to miss if you were listening in a loud place. It's not an initial sound of realisation. It's not an attempt at defiance. It's not Eiffel trying to plead with Pryce or snap Minkowski out of Pryce's control. He'll do those things later: yelling at both Pryce and Minkowski, banging against the airlock door, crying out in desperation. But before that, he breathes the word No, and he's not trying to communicate anything to anyone. He's just whispering No, expressing beneath his breath - perhaps unconsciously - that this cannot happen. Minkowski cannot die.
