During the SummerSlam Kickoff show, they did a backstage segment with The OC (AJ Styles, Karl Anderson and Luke Gallows) and their long-time friend Finn Balor.
Balor talked about his SummerSlam match with "The Fiend" Bray Wyatt. The OC said they were willing to help him out if Balor needed it. The segment ended with The OC walking off and Balor looking into the distance with a conflicted look on his face.
This could be the seeds being planted for a heel turn and there have been rumors backstage at WWE about Balor being added to the group at some point.
If Balor turns heel and joins The OC then it might not happen for a couple of months because Balor is scheduled to take time off from WWE after SummerSlam weekend.
