I am liking he idea of Rey/Kane feud coz it once again builds up Rey( Stupid way to do it but it works) and gives kane something to do.
I also see a gimmick match down the line between the tow of them and from what Kane was saying about Rey hiding behind the mask could lead to a Mask vs Mask match with a difference and that being if Rey loses he removes the mask and If Rey wins Kane has to return to using his mask.
