The more I watch, the more I realise how well Jack is playing the game. He is in the 'Alliance' but he seems to be the one the Ex's seem to be able to communicate best with from the opposition - I assume he seems harmless to them at this stage. He will be the last one the Ex's pick off from the Alliance but by staying loyal to the Alliance he keeps them onside...
he talks a lot of strategic rubbish
I do however admire him for using that haircut as a disguise to lulling them into thinking he is an idiot. Good thinking Jack
