If they're going to be stuck inside anyway for most of the day, and unable to keep to their previously-regimented schedule, the Soldier figures they might as well corner Aziraphale to work on... a few things. They did make that resolution, after all, and are considering another that a technicial(/angel) might also know something about.

So, shy but determined, they ask after breakfast and after Crowley has wandered back upstairs, "Can I talk to you for a bit."
