#1. The Rock took Vince McMahon's egg back himself
Vince McMahon made it clear that The Rock was the one who gave him the egg recently. Cleopatra's Eggs form the crux of the plot for The Rock's new movie Red Notice and it appears that WWE believes this could tie in well for a storyline.
McMahon was obviously irresponsible with the egg and decided to leave it out in the open whilst also parading around with it in front of his entire workforce.
If anything, McMahon put himself in this position because he wanted to show off his wealth. The Rock has always been a very humble superstar and despite having money he has never thrown it in anyone's face.
The Brahma Bull may not have been the man to take the egg from Vince McMahon's office last night, but he could have asked someone to do it for him. Either way, this could tie in well for a return to WWE for The Rock and help set up a feud heading into WrestleMania next year.
