I know they’re young and all, but surely being stoned and enslaved would be enough of a deterrent to wander out into the open without supervision. Hell, their natural parents died early because of their defiance. Now our MC and his ‘servant’ will probably have to shred the town looking for them. Hopefully they’ll see that they not only endangered themselves, but their caretaker too, and won’t ever act so capriciously.
Would be a nice change of pace if the old man was truly just being helpful. The fact that he saw that no one was around to verify they were twins is a good sign; that and not calling anyone over.
