#3. The return of The Demon
Finn Bálor is the face in this rivalry, but given the fact that he has been hardly used on TV or given much of anything to do since his move over to SmackDown Live, the return of The Demon could be needed.
Nakamura has defeated Bálor twice now and has made it look easy both times. Bálor was able to successfully defend the title in Saudi Arabia when he took The Demon with him to face Andrade. This could be a hint that Balor needs his alter-ego at SummerSlam if he's granted a rematch.

It's also worth nothing that Bálor has brought the Demon with him at every SummerSlam he's performed on.
Bálor wasn't impressed with the loss and will definitely be looking to avenge it. Don't be surprised if the face paint is back out next month and Balor is looking to reclaim his Championship.
