Cena made his return to WWE on Sunday at Money in the Bank, confronting Reigns after Roman defended his Universal Championship against Edge.
Cena made the "You can't see me gesture" at Reigns before posing as the show went off the air. Reigns offered no response in the ring, but did take to social media to comment on Cena's return.
Cena had not appeared on WWE television since literally disappearing inside the Firefly Fun House at WrestleMania 36 against Bray Wyatt.
