The mystery surrounding Jacob Fatu's secret attacker on WWE SmackDown has kept the fans buzzing over the last couple of months. Amidst this, the company dropped a subtle hint that Solo Sikoa might be the attacker on RAW this week.The Samoan Werewolf was taken out backstage by an unknown figure on SmackDown's October 17 episode. Considering that Fatu was amidst a feud with Drew McIntyre at that point, many assumed he might be behind the cowardly attack. However, McIntyre firmly made it clear he wasn't responsible.Since then, there has been little development in the storyline, with WWE focusing instead on the build to last week's Survivor Series 2025. However, with the event behind us, the company might now bring the mystery back into the spotlight. This week on RAW, Solo Sikoa was spotted looking at Jacob Fatu's picture on one of the promotional trucks outside the arena.While it's mere speculation, there's a chance the global juggernaut might be hinting at Sikoa being the mystery attacker who took out Fatu.Jacob Fatu is close to returning to WWEBefore his hiatus, Jacob Fatu looked set to challenge Cody Rhodes for the Undisputed WWE Title. However, a dental injury forced the company to pull him out of action and book the backstage attack angle to write him off TV. However, recent reports suggest The Samoan Werewolf might be on his way back now.As per PWInsider, Fatu is slated to return to the road in the coming weeks. While fans would love to see him challenge Cody for the gold, it's safe to say the former Bloodline member would first focus on identifying the person who attacked him. Regardless of who he feuds with first, there's no doubt that Fatu could receive a monster push once he's healthy and fit to step inside the ring.
