Video: The Rock, Roman Reigns Talk WWE WrestleMania 40, More with Jimmy Fallon

Ahead of WWE's biggest event of the year, The Rock and Roman Reigns stopped by The Tonight Show Starring Jimmy Fallon to discuss all things WrestleMania 40.

One of the main topics of conversation was Cody Rhodes and his quest to "finish the story" by beating the Tribal Chief for the undisputed WWE championship.

Reigns said The American Nightmare might be "reading the wrong book" at this point because "we don't care about his story."

"In the wrestling business, there's no call sheet. There's no, you know, like he's number one, he's number two, so everybody on our roster believes they're number one. So it's just a shark tank," Reigns explained. "Everybody's trying to take each other out, and this guy's been chasing me for two years now. I've beaten him. We've crossed this bridge already, so this is where we close the book completely on this guy, Cody Rhodes, and we display what the most powerful family in pro wrestling is all about."

In response to Fallon asking if he thinks that's what is going to go down, The Rock responded: "I know that's what's gonna go down."

Before they dove headfirst into building up WrestleMania 40, the two WWE superstars also talked about their life and careers up to this point. The Rock and Reigns touched on their background as football players, some of the history of the Bloodline in pro wrestling, including Rock's dad squaring off against Roman's dad in the ring many years ago.

The Rock will be wrestling his first full match since losing to John Cena at WrestleMania 29. He did have an impromptu bout with Erick Rowan at WrestleMania 32 that ended in six seconds.

The Great One will be teaming with Reigns against Rhodes and Seth Rollins in the main event of night one on Saturday night. If the Bloodline wins, the Reigns-Rhodes match on Sunday will be Bloodline rules. If Rhodes and Rollins win, the Bloodline will be banned from ringside for the WWE universal championship bout.

Since the birth of the Bloodline faction three years ago, everything has been leading up to this moment. WrestleMania 40 is going to be the culmination of one of the best storylines in WWE history.

It's either going to end with Rhodes finishing his story to become undisputed WWE universal champion for the first time in his career, or Reigns retaining the title to continue what has been thus far the fourth-longest championship reign in WWE history.
