Answer 4

I still think that there is yet another swerve to come. The opened bag segment was only to hype Mysterio's return and set up a fresh feud with Kane seeing there were pretty much no options around for him. We will soon find out that Kane had switched articles in the bag in order to show Adamle when he was forced to, then act like it was really that in which he was talking about when it wasn't, and that it's still being kept a mystery.

The things Kane brought up during this whole time didn't have a single connection with Rey.
