Who were the two apprentices for Amalek in The Bronze Bow?

In Chapter 1, Joel and Malthace climb the mountain and Daniel recognizes Joel. Daniel introduces himself as Daniel bar Jamin, and Joel remembers that Daniel was the apprentice who ran away from the blacksmith, Amalek. Joel tells Daniel that nobody blamed him for running away because Amalek treated his boys terribly. Daniel asks Joel if he can tell him anything about his grandmother, and Joel says that he cannot. Malthace speaks up and tells Daniel that there is an old lady who gets water from the well and people say she lives with a little girl who never comes out of the house. Daniel then asks Joel if he knows a boy named Simon who is six or seven years older. Daniel tells Joel that Simon was also an apprentice bound to Amalek. Joel explains to Daniel that Simon has his own shop now and gets more business than Amalek. Daniel asks Joel if he can send a message to Simon and tell Simon that he is living in the mountains. Daniel fears going back into town because he does not want to get dragged back into Amalek's shop.
