#2 To confirm Samoa Joe's babyface turn
Samoa Joe made his NXT debut as a babyface who saved Sami Zayn from the brutal attack of Kevin Owens, but soon he turned heel and started destroying his opponents one after the other. Joe made his main roster debut as the henchman for Triple H, as he ambushed Seth Rollins when he tried to attack the King of Kings.
Since then, Joe has always been a heel. However, if you observe Joe's commentary on RAW, you can tell that he comments as a babyface. He has openly criticized the actions of Rollins and the Authors of Pain, cautioning the babyfaces of RAW about the potential attacks of the AOP & Seth Rollins.

A heel giving such warnings to the babyfaces and criticizing heels is an uncommon act in WWE - even for commentators. Corey Graves, the heel commentator on SmackDown repeatedly justifies all the actions done by the heels of the Blue brand.
The attack on Joe by AOP confirms that the Samoan Submission Machine is now a babyface. We can add him to the list of Superstars who shone as heels but have recently transitioned to the 'good side'.
