How much now? What should be later? And still rope in the reader

The emotional tension between Alexa and Pearson is building nicely in this scene.

Now the question is how much now, how much later. How much info to divulge to Alexa now, and later, each step of the way.

How much would a normal person wonder, by now at this point of the story ? IE, Alexa NOT asking would make her appear an idiot, which hopefully she is not.

How much info moves the story on nicely, but avoids spoiling the point?

What kind of response would be logical, and ALSO titillate in what it avoids revealing, roping in the reader to keep turning the pages?

This process appears to consist of writing, then perhaps deleting or cutting and pasting for a later scene. Then writing again in a different direction.
