Jean Riudaure returns to Westcrown on the morning of the 5th, with a resurrected Archduke Blanxart and three agents of Lastwall tasked with writing the official failure analysis for the events of the third. They are aware that showing up after the dust has settled to write a failure analysis of this incident might be taken badly by the nobility of Cheliax, so formally their duties are to aid Cheliax in anything she may require in responding to the riots, and only as a secondary priority or when that task is done to figure out what happened. Interviews are most useful when fresh, so they've already done Riudaure's, but the rest will probably wind up having to wait.
The formal duties aren’t a pretense; they get to work hauling rubble out of the streets and making house calls for healing. But they also write the palace requesting, if it's possible, an interview with Valia Wain for the purpose of aiding the church in avoiding similar errors in the future. That's time sensitive not only because she might forget details by next week but, because Cheliax might well put her to death by then. They don’t request an interview with the Queen or with the archmages, as there’s not much reason to think they'd be granted one and they’re trying not to add obligations for anyone else, here.
