Murphy will tell them everything he knows and he'll do it without hesitation. He'll go into as much detail as they want about the gods and the creation of the Aerie and what being chosen entailed. (I don't actually know most of the details here but he'd give them everything he knows and answer all their follow-up questions with straight honesty, same as he did when he was taken hostage.) From his tone, he doesn't find any of this spiritually significant or profound or precious, so why would he hold onto any of it? He has no interest in protecting the gods' secrets.

He'll also say he's not sure if the rebel who kidnapped and interrogated him is Displaced but that he'll be keeping an eye out for that face and get back to them with a name if he can catch it.

Other stuff in his preliminary report!:

From what he's heard, newcomers who arrived during the Aerie were escorted over from New Tokyo by the Displaced who'd already returned, but he doesn't know more than that. The newcomers are all cagey and suspicious of the other Displaced, so they're not chatty, but he'll work on it.

So far, the Displaced seem curious about the gods and there are some people talking about trying to "connect" with them, to figure out whether they're a threat. Others are talking about trying to prevent the gods from interfering any further, though no one's pitched a real plan about how to stop them. He'll keep listening.

Henries is a great big mystery to everyone, but he'll let them know if anything comes up.

He hasn't had any visions. :'(
