The relief is palpable as Robin gives Phalanx space and stops trying to take away their things. No promises that their hair will halt in its change from one color to another, but they do shut up and keep their head down, so maybe the good tailor won't notice anything too strange.

They're content to keep their attention quietly down at the things in their hands (while they're still out in the open, anyway) and even halfway turn their back on the other two people there, to keep their trinkets safe.
