IMO 3 of the 4 layers:
1- SA, KS, JP all posted,replied, and liked that #17 number. All AFTER they went against Q
2- SA, KS, JP, all 3 of them are followed by DJTjr.
3- SA,KS,JP all 3 of them went against Q about at the same time
4- This one is less sure than the others: all 3 of them went against Q, but just CAN'T LET THE NUGGET GO. They tweet about it even more.
All these are IMO so don't take for granted, do your own research on this. I find it quite interesting.
