Roman Reigns and Solo Sikoa are currently at war on SmackDown over the title of The Tribal Chief of the Bloodline. The former Bloodline allies engaged in battle this week, with Sikoa standing tall at the end of the night. The Ula Fala played a crucial role in proceedings as the new Head of the Table challenged Reigns to come and take it from him.However, the WWE Universe was once again teased with a glimpse of who could be next in line for the throne of The Bloodline: Tama Tonga. The MFT stood beside Sikoa, who passed him the Ula Fala so he could square off with Reigns. He held the red Samoan necklace tightly and looked charmed by it.This could signify that Tama Tonga is eyeing The Head of the Table gig and could even be plotting to overthrow both Sikoa and Reigns. It's the second week in a row he's had a 'mysterious' moment with the item, as he was mesmerized by it on SmackDown last Friday too.Roman Reigns took out Solo Sikoa and Tama Tonga and regained possession of the Ula Fala. He put it on but was attacked by a returning Jacob Fatu, whose ambush led to all three putting Reigns through the announcers' desk.Solo made it clear earlier in the night that whoever has possession of the Ula Fala is acknowledged as The Tribal Chief. Tama Tonga could make a shock betrayal and assume The Bloodline leadership for himself.WWE SmackDown: Solo Sikoa should have listened to Roman Reigns' WisemanSolo Sikoa's tyrannical reign as the new Bloodline leader saw him part ways with Paul Heyman in June.

The Special Counsel had refused to acknowledge Sikoa as his Tribal Chief.Paul Heyman had previously tried warning Sikoa about the type of individuals he was recruiting in the new Bloodline. In May, the WWE Hall of Famer told the former Tribal Heir about their thuggish backgrounds, but his advice wasn't heeded.Sikoa's decision to ignore Heyman's concerns might come back to haunt him. He may have a group of mercenaries secretly preparing to betray him. This could be why all three were willing to come on board when the new Bloodline leader invited them into his group.Roman Reigns knows all about betrayal, as he was turned on by Seth Rollins when The Shield shockingly disbanded. The WWE Universe might see him warn Sikoa about the threat the new group brings and raise question marks about whether he can trust them.
