[Archie pays close attention to Ginia's instructions, and therefore, close attention to Ginia. He doesn't make a mental list of anything he sees, but what he does see makes him tense even though he's hardly trying to read her. He couldn't name it, and he couldn't put his finger on exactly what it is about her tonight.
A person more learned in psychology or body language might be able to say it's the way she pauses every so often to pick up her train of thought, how she loses track more easily than usual, how she's slightly pale or her smiles don't quite reach her eyes. How she rushes and doesn't dilly-dally on tangents, or any number of other slightly off behaviors characteristic of someone very practiced at hiding when they've been triggered. Archie can only tell that something about her is making him feel oddly gloomy.]
[Action] Tell me if this is okay.

Thank you, Ginia.
