Carlota contemplates the desserts, trying to determine if she's lost her appetite in a lasting way or if it's just the adrenaline and she should tell the staff to set aside a plate for her. It's not worth thinking about. There's a lot here worth thinking about - if Razmiran is Hell's next attempt to gain a foothold on the Material, if the Queen is bound by a secret deal not to stop Mephistopheles from ruling a country on the Material, that's really quite important. The desserts are not. 

Set aside a plate, figure it out later, go to the palace - no. First she should consult with her fiancé. 

 “I’m going to go speak to the Queen, unless you’d prefer to. Or we could go together, and do some additional planning while we wait.”
