The Archduchess wants the Songbird to consult on the legal clause she's writing, and she shouldn't be in a committee right now. So Ivette has been tasked with finding her and bringing her over, as promptly as possible.
Now, where would she be?
Laia has post-giving-a-speech-to-the-convention drop. As soon as the floor meeting was through she cancelled her own committee, sending Eloi around to tell everyone it was off today, and took him out for ice cream. She is sitting under a tree in the park with her bodyguard (who refused ice cream) lurking nearby and Eloi at her hip.
And they'll be forewarned and also Ivette will tell the Lord Mayor that Solandra seemed exhausted and she should probably keep that in mind.
