The Restorer listens to this, with a look of focused attention. At the end, they sign "I see" at the same time as opening their mouth to emit a SCREEECH.
When they see someone startle at this, they sign "I apologize. Could you all look away for a moment?"
They put their fingertips back on their throat and massage it thoughtfully. They then walk up to the wall of the tent, and when everyone is looking away, there is a warble, just the same as in the recordings of the first contact.
When everyone looks back the Restorer has walked back to where they stood, now experimentally sounding out vowels. If someone peeks into their mouth, there is a black tongue and marbled teeth instead of the earlier baleen.
"Aaa.Ooo. O- A- Eee"
They then move on to the consonants, in the same order as Vornmeth described them in mindspace.
"Pa. Ta. Ga. Na..."
They start experimenting their way through longer combinations of phonemes, and try some sentences out.
"Oadev is oed. Wader is wed. Water is wet. Water is wet."
"The trickest bart is brobably. propaply. Pro-ba-bly. The voice box."
"The trickiest part is probably the voice box."
"A hurricane is powered by the evaporaton. Evaporation of warm water off of the surfaf. Surface of the ocean."
They then address Vornmeth again, now mimicking him in speaking-and-signing. People around may notice that the Restorer has inherited any dialect or idiosyncracies that Vornmeth has when speaking.
"I have some doubts about whether I can affect the hurricane directly. Air is not my domain, the scale is grand, and my power here is limited - I am far from the depths and thus my connection is weak. Perhaps there is something I can do to encourage the water to redistribute in such a way that less warm water is close to the surface of the ocean, so it doesn't... Evaporate?
Communing with a meteorologist may well give me the understanding required to know more.
What other areas of the emergency response may I be helpful in?"
They look around the room. If there is a standard for which roles are filled during an emergency response meeting like this, they'll start identifying people in the room from clothing or context clues, with only slightly worse accuracy than Vornmeth would if he found himself in an unfamiliar team. ("And you must be the diplomat..?")
Who is there with them?
