@Gordian NoughtSure, we can assume that to be the case. I'm not sure what you would use your bonus action for on the first round anyhow, but I don't see a problem in him being wary at a time like this. Usually when it comes to stealth checks, things like this affect them, but since I rolled them this time around you didn't really have time to react. If this is the kind of behaviour I should expect of Torus, I'll keep it in mind for future checks.
In general, if there's anything you think your characters would be doing consistently when moving around, do inform me of it so I can take it into account if things come up!
