(urth) Why Berthold looks like Ben

[Andrew Bollen]

At the end of Wizard, when Art is wearing his magic helm. I think that 
previously, Berthold would have looked like Berthold, helm or no. Art wears 
the helm a lot and Berthold is around, in all of the fighting leading up to 
this; and the appearance of Ben in place of Berthold after the River Battle 
is obviously a surprise.

The big change is Art's healing of Bert, in which "it took a lot to restore 
the thing he had left in a pond, so long ago." We know that Art doesn't have 
the power to restore the dead. I think the point here is that the "thing" 
which Ben lost in the pond is indeed dead. To restore him, Able has had to 
replace it with something taken from or copied from (a memory of?) Ben, 
though it seems that Art himself doesn't realize this.
