Manipulation

As Daneel heard this tirade, he didn't know how to respond.

First of all, this wasn't some well-wisher of his who was saying this for his own good. The Head gave him all kind of negative vibes which meant that there was no way that Daneel would trust the man, and, besides, this was only the second time they were talking.

Secondly, the way he spoke about how all those below them might die was troubling, to say the least. Was the Big 4 sure that there would be massive casualties in the war that was to come? Were they prepared to let that happen with some endgame in mind?

A lot of questions appeared in Daneel's mind, but, sadly, he couldn't ask any of them.

So, he just stoically stood there among the clouds while the Head glowered at him for a few moments in silence.
