The envoy, after the two go, informs Sevar that they are to follow silently behind; she's to watch this interview through an illusionary wall, so that a nearby spellcaster running Detect Thoughts can keep half an eye on Sevar's own thoughts, in case she wants to loudly think anything important. If so, the information will make its way to Isidre Thrune, who has one of the highest Splendours that could be found on this much notice.
Also Maillol is temporarily unavailable for a while and Sevar is back in charge for something like the next half-day.
