The fabric of reality feels weak to Sam and he's been spending every day, fully prepared as Wallmaker and walking and exploring. He doesn't know the right spells to understand and see what's changing.
Instead he has to rely on the little he knows as Wallmaker and his own knowledge of the Charter to try and understand. Currently he's standing near one of the walls, trying to find one of the points of wrong to focus on.
When the lady in
grey walks through the door, his hand moves to his sword hilt and stays there. This is the kind of thing he's meant to know how to stop, how to mend, and he doesn't know how.
