What happened?

..well, we'd have to start @ Summerslam.
Long story short, Kevin Nash came out to screw CM Punk out of the title.

The next night on RAW, Triple H (
now the WWE's C.O.O.) comes out and says how he; "knew Nash would be @ the PPV, but had nothing to do with the run in" -paraphrasing.
Kevin Nash comes out and says he; "got a text on his cell to stick the winner from a friend" and asks Hunter to come clean, so that they can be on the same page. CM Punk comes out, to a great back-&-forth with Nash.. eventually leading to a secret meeting between Nash and a WWE exec.

This brings us to last Mondays RAW, where we saw Nash once again come out with HHH.. and both try to cover up to the fans. CM Punk comes out and calls bullsh!t, leading to Nash attacking Punk, and HHH throwing Nash out of the building.
Later in the show, Hunter is informed that Nash was in a car accident, in order for him to leave the building, so that Nash can make his return.

This is all leading to a Kliq reunion of sorts, when it will be revealed that it was Shawn Michaels (
and I'm just speculating the rumor-mill here) is the one who texted Nash as the RAW GM, culminating in an eventual heel turn for Hunter.

Really love where the WWE is going with this one.
Some may or may not remember the; "corporate establishment -vs- Austin" storyline in the 1990's. The corporate establishment being; Paterson, Brisco, & Vince.
If WWE creative plays this out right, that can have a reboot of that angle, with Punk playing Austin.. and the Kliq playing the "stooges".
