I sort of allowed the liberty to assume that Beryl would be somewhat in ordinary sending range. Maybe a bit far away, but Alex may turn out to be an avid sender while excited...
Maybe even somewhere deep in the bowels of the ship rather than at her bridge station, but the idea that Alex did achieve something extraordinary with it has some merit. And, given the current events, no one might have found the time to seriously stop and think about it.
But, if Beryl, or Tempo, may slow down and revisit that moment, they might have a "hey, wait a minute...!" moment.
And perhaps enough reason to revisit their initial musings about human telepathy and the origins of their Lotai. But surely all of the Loroi would be much more interested in the extent of his telepathic abilities, and if they come with other things like telekinetics, too.
