I still think there's a chance Reigns failed the test on purpose.
He's been stuck in a "slow talking once bad guy now redeemed" character who everyone knows everyone has hated for years, probably including him. He has no backstage leverage to get out of it since all WWE has to do is (correctly) say "you're nothing without us." So he sabotaged his redeemed image in an attempt to come back as something interesting.
I rest my case.
