Amir is re-convicted on December 15, 2013. Neither he nor his lawyer are present for this trial and it isn’t until much later that he or his family are made aware of the new development. 
Personally, I saw this a step forward in the case, as it sets a baseline from which we can only improve for Amir, and it seems to indicate to me that this is something that the Iranians want to move forward on. 
I know that seems odd; a ten year prison sentence is never GOOD news, but I have to believe that it is just the opening step in the end game that will bring Amir home.
