Mhalir considers his reply to the Andalite commander.
He agrees that getting on the same page about the announcement to be made is a priority, and needs higher-bandwidth. He is, predictably, unwilling to go up to the Dome ship. He'd be willing to meet face to face again with Leareth, though, down on Earth, if Matirin could brief him on everything and send him as an envoy.
(Enstat and the various other Yeerks in favour of voluntary-only Controllers may end up quite pleased with this outcome, he thinks. If, and it feels like a big if, the Andalites are willing to be anything like reasonable about interpreting which hosts are voluntary ones, instead of assuming anyone who wants their Yeerk back must only be saying so because they're traumatized.)
...Given that, though, it could make sense to send some of the voluntary human hosts up to the ship to present their side of things to Matirin and be human advisors on how to present this to the human governments. Just hosts, of course, without Yeerks. He adds this suggestion to the message, and passes on to his staff to spread the word about this and ask if anyone on the voluntary Controllers side is willing to temporarily part ways with their Yeerk.
