Meanwhile, some fans believe the duo had hinted at the controversial finish in an interview last month.Jey challenged Roman Reigns for the Undisputed WWE Universal Championship and his Tribal Chiefdom. The latter had plenty of help from Solo Sikoa, but Jey came close to picking up a win on multiple occasions.The match's closing moments, however, saw a shocking twist as Jimmy Uso returned and betrayed his brother. He prevented Jey from defeating Reigns and indirectly helped the latter retain his gold.While Jimmy's betrayal could have several potential reasons, many are convinced it will eventually lead to a massive WrestleMania match between the two brothers.A clip from their interview with Ariel Helwani recently resurfaced on social media, where Jey Uso said facing Jimmy at WrestleMania was his dream match.
