Soldat's response to the comment is immediate contrition. After all, it got all tense and terrible because they melted down, here. So the look they cast Misty is absolutely apologetic, and they settle back down at the table with the notebook, finding a clean page near the back to start writing down options.

"Sorry. I'll try not to freak out again. Having a plan helps." They write down the three names they'd thought of at the top of the page, first, for Misty to see-- Rhys, Daylight, Rosalind Lutece-- and then give Sora a sidelong look. "It's possible. Sure." Yes, they recognize the attempt at humor. Yes, they are tackling it with their own dry blandness.

They start writing things they know about each name under their heading. They need intel. Gotta see where their holes in knowledge are.
