The Young Bucks unsuccessfully challenged for the AEW World Tag Team Championships at All Out earlier this month. The former EVPs were involved in the four-way ladder match against JetSpeed, the Don Callis Family, and the current champions, Brodido.Following their match, they were confronted by a returning star who used to be their friend and teammate. The star in question is former TNT Champion Jack Perry, who split from the Bucks on his return and joined forces with former tag team partner, Luchasaurus, reuniting Jurassic Express.Jack Perry was part of the Elite with the Young Bucks before his absence, but things changed during his time away from the company. The former AEW World Tag Team Champions dropped a cryptic message following Jack Perry's betrayal.They have changed their Twitter [X] bio to just a knife, hinting at the knife Jack Perry has been sporting. The change in bio can also be seen as the Young Bucks feeling as if they were stabbed in the back by their former stable member after Luchasaurus attacked them at All Out.Former AEW Champions to make first appearance at Dynamite since reunitingThis week's edition of Dynamite is set to be an exciting one, as it is set to be a special two and a half hour long episode.
