He nods his agreement to what Winter says. He put it very well.
To Philip on the matter of drinks he says "I will go with the homebrew beer, personally. But I will certainly honor the cookies."
Then Philip calls Aurora out for ... he is not exactly sure what. He turns to Chambers and whispers "When did Aurora say that she will answer the questions? "
Ah. And then he sees the other Aurora. Yeah, he will keep his questions for later. As Aurora gets more and more heated in her answer he notices she mentions the artifact and bites his lip... he would be much happier if that didn't slip out. But he is sure everyone would mistake his discomfort over that as a reaction to Aurora's answer.
And Aurora still leaves out what he thinks are some of her best accomplishments he takes a breath, thinking whether he should risk to add ... and decides not to. But it burns in his mind.
Once Aurora runs out of breath he ... nope. He doesn't say anything except "We all value your presence, Aurora." Well, except Puck, but he left. " Philip, the Acquisitor never promised answers, just that she will listen to questions." And I will tell them that Aurora speaks a bunch of languages that nobody else speaks at a different time. And they will find out about how good her beer is soon enough. No reason to risk swimming with the fishes.
