#3 John Cena shows up to congratulate Flair and set up his WrestleMania match
While Flair has had a great career in wrestling, holding the record for the maximum World Championship reigns in history, there is a guy who shares this record with him. Yes, we are talking about The Champ, John Cena.
Cena last made an appearance on RAW in January. He was replaced in the Royal Rumble match, and currently, there is no confirmation of him having a match at this year's WrestleMania.
John Cena returning to RAW to congratulate Flair on his birthday would be a great moment. Cena could also tease his intentions of breaking the record of Ric Flair and winning his 17th World Championship.
Another interesting thing could be a staredown between John and his rumored WrestleMania opponent, Drew McIntyre. This would be a great time to kick-off this rivalry if this match gets booked for Mania.
