:Oh oh oh can you show us a memory that sounds so pretty–:
:We have SO MANY birds. I think there don't need to be that many birds:
:Do you eat the same things Companions do, we can show you the greenhouse that has nice grass even in winter–:
The foals are so curious and delighted to talk to him and ask a million questions; the adults give them periodic hushes and tell them to go one at a time, and they remember for a while, but they're so excited. They show him the greenhouse with grass in it (though the Companions mostly eat grain and stored hay, in winter, since they can, but they're not sure he can.)
The Companions talk to each other constantly, in Mindspeech. Even the ones who aren't talking directly to Alloran don't bother to shield it out, so it's like being in the same room as half a dozen conversations, which can be ignored fairly easily but are there if he wants to pay attention. They're gossiping - about their Heralds, and the war that Valdemar just won with the Andalites' help, and Queen Karis, and whether it'll be a good harvest next year.
Emotions aren't hard to read, when everyone is Mindspeaking and leaking overtones, and none of them are at all resentful about his disability. They're very curious about his world and his people, and pleased to have him here.
