This is TdF. there are no friends, only DS. if DS says midway thru TdF tht Porte is the new leader, then it will be so. if Porte gets more than 2 min from Froome before the TT, then he becomes the leader as per the Sky Logic.
But froome being froome. he will ensure tht porte loses a few min so that he wont challenge dawg's spot.
