#3 Turn heel
At this point, the members of the WWE Universe are beginning to wonder when Dean Ambrose will turn heel.
After their victory over The Dogs of War on the most recent episode of RAW, the bond between the brothers seems stronger than ever, but tensions remain. The tension will only get worse once Dean publicly acknowledges that he doesn't have a match at Crown Jewel, which might probably happen on the upcoming episode of RAW.
At this point, Baron Corbin might choose to interject himself into the situation and remind Dean that Seth cost him his opportunity to participate in the WWE World Cup.
Baron, being the nice guy that he is, would create a match between Dean and Seth, for Seth's spot in the World Cup.
If this happens, fans could get the Dean Ambrose heel turn they have been longing to see. The tension might rise to a boiling point, and Dean would finally snap at Crown Jewel, taking out both Reigns and Rollins during their matches.
Since Braun cast aside Dolph and Drew, they could choose to align themselves with Dean and form a stable.
