On last week's episode of WWE RAW, Jey Uso lost to LA Knight in the semifinals of John Cena's Last Time Is Now Tournament. This week, he reunited with his twin, Jimmy Uso, to put AJ Styles and Dragon Lee on notice after they successfully defended the World Tag Team Championship against The War Raiders (Erik and Ivar).Despite announcing his return to the tag team division, many still believe that The YEET Master is on the verge of embracing his sinister side. In this listicle, we will explore four signs that Jey will soon turn heel in WWE.#4. Jey Uso could take his frustration out on Jimmy after returning to the tag team division instead of being in the world title sceneIt appears that Jey Uso has lost his chances at the World Heavyweight Championship after losing to CM Punk at Saturday Night's Main Event XLI, which has led to his return to the tag team division.Given that The YEET Master might be understandably unhappy with being sidelined from the world title scene, he could vent his frustration on Jimmy Uso for being placed back in a tag team. This emotional response might trigger a heel turn for Jey.#3. Reunion with Jimmy Uso could lead to a heel turn if they fail to win the tag team title down the roadJey Uso has experienced some difficulties in reclaiming the World Heavyweight Championship since dropping it to Gunther earlier this year on RAW after Money in the Bank. However, he now plans to regain momentum by reuniting with Jimmy Uso and pursuing the World Tag Team Championship.Therefore, there is a strong possibility that The YEET Master might embrace a heel character down the road if The Usos fail to win the tag team title. Another huge loss might be difficult for him to handle.#2. Still no payoff from the Roman Reigns-Jey Uso angleThe creative team has yet to develop the storyline between Jey Uso and Roman Reigns. The OTC advised Jey to always put himself first and trust no one, and it seemed The YEET Master had heeded the advice before eventually joining forces with CM Punk against The Vision while Reigns was away.Given the recent setbacks Jey has faced, he's now likely to adopt Roman Reigns' mindset, which might eventually set him up for a heel turn.#1. Jey Uso could be LA Knight's mystery attackerLA Knight lost to Logan Paul in a one-on-one match on the go-home edition of WWE RAW ahead of Saturday Night's Main Event XLII, thanks to a mystery attacker who attacked Knight with Seth Rollins' Stomp.This situation has led to much speculation in the wrestling community about the identity of the hooded assailant. Surprisingly, Jey Uso could be behind the disguise, as he was defeated by The Megastar in the semifinals of The Last Time Is Now Tournament.Given that The YEET Master might be holding a grudge, he could be the mystery attacker.
