#1 The Kevin Owens and Vince McMahon Situation

In the opening segment of this past episode of SmackDown, the tension between Kevin Owens and Shane McMahon boiled over after Owens spoke ill of Shane's family, saying they would have been better off if he had not survived his helicopter crash.
Shane lost it, attacking Owens and prompting him to threaten to sue WWE to bring it down, which was a call to action for the head honcho to step in to mediate things.
At the moment, Shane is indefinitely suspended and Vince McMahon will address the situation personally with an appearance on SmackDown.
Of course, we know that whenever Mr. McMahon steps in front of the cameras, it isn't going to be something as simple as him apologizing to Owens and sweeping this under the rug before wishing everyone in the crowd a happy rest of the program.
This will somehow lead into the next phase of the story between Owens and Shane which seems to point to a Hell in a Cell match the two will have come the October 8th pay-per-view, particularly as the Shinsuke Nakamura vs. Jinder Mahal match hasn't been announced as taking place in the cage.
Granted, Vince may not directly announce this on SmackDown, and this could even be a different scenario where Owens attacks Vince out of anger and Shane gets reinstated that way, fighting on his behalf, but the safer bet is to go with the simpler option.
My guess is we'll see some showboating to the crowd from Mr. McMahon before he simply states that the Hell in a Cell match will take place and that the two of them can't touch each other beforehand so we don't see them clash on the next few episodes of SmackDown leading up to the event.
