Willa feels a bit chastened; she was so eager to 'step outside the solution space' that she probably went too far. And looked stupid again.
But it occurs to her now that even if you were trying relatively risky experiments, you might not have to actually try them all: you could just decide on what experiments you might do, and then use Auguries or even more powerful future predicting divinations to see if it would lead anywhere or not. It'd be a little bit error prone, but it'd also be much cheaper and faster than going without.
This is an idea borne of magical knowledge though, and so it might be more than a little dangerous. Especially because getting Keltham into the habit of preparing and using too many divinations of that sort could end up going pretty badly. But then again, it's the kind of thing Keltham will probably think of doing himself before too long, and it might make the conspiracy universe more probable if all these other people more used to having magic available didn't suggest it first.
She thinks loudly at security to ask Asmodia if she thinks mentioning this Augury-pre-experimenting line of thought is worth the risk.
