1. It adds more depth to the speculation surrounding Dean
It has been going on for a while. A heel turn is expected from Dean which would cause yet another split of the Shield. The longer this feud goes, the more suspense it builds and with Dean acclaimed to be mentally unstable on screen (as per his character), it just adds to it. Nobody wants to see the Shield split up. At the same time though, nobody would mind a Dean vs Rollins vs Reigns. Dean Ambrose received the loudest pop of 2018 when he returned and him turning heel would generate an even better response.
