Question: If Jack and Graem are brothers, why has there never been any mention of their relationship before, even in passing? And I'm talking beside the fact the producers didn't make them brothers until season 6.
Chosen answer:There really wasn't any need for us to know he had a brother before - for all we know, he could have more than one brother but the need for us to know isn't there...just like there isn't any mention of his mother - who, for all we know, could be the mastermind criminal behind everything. Bear in mind over the near 10 years in the show's time that have elapsed over the 6 seasons, we've only spent 6 days in Jack's company - no reason his brother would have come up.
