It sounds like "posté" but I can't think of any English or French word that would make sense in the context. Is it a German term? I've looked up several iterations of the script and none kf them contained that one-word line in them.
It's something that's been nagging me since the movie came out, and if someone has the answer, I would be extremely grateful!
