User blog comment:Merlin artist/Balinor's in the finale?!?!?!?/@comment-142.166.196.61-20121218174359

In regards to the "brother against brother" line - I think you're SERIOUSLY reaching if you think Mordred is Merlin's half brother. There won't be anything like that at all. Quite simply, Arthur has said several times now this season that he considers the knights his "brothers". It is knight against knight - as in just another way to say Mordred has betrayed them.
