Before Solo Sikoa and his bloodline beat up Jimmy Uso and the OTC Roman Reigns on Friday Night Smackdown, Solo was face to face with Jey Uso and they had a fiery promo.
Solo Sikoa requested that Jey Uso should acknowledge him but obviously Jey will not acknowledge Roman let alone Solo.
Jey told Solo that if he wants Roman's power he can try to earn it but he should destroy the family while trying to do it. Solo responded by saying he's actually trying to unite the family.
Jey USO then questioned Solo, that if he's trying to unite the family why did he have to go and get Tama Tongo, Tonga Lao and Jacob Fatu.
He made another statement which is my proof that he'll help Roman. He said there's a reason why their family stay away from The Tonga side of the Samoan family.
That means there's a conflict between those people and I think because of that, Jey Uso would rather join Roman to fight Solo and that side of the bloodline. Jey Uso also said that the next time he meets Solo it's going to be different.
So apparently, Jey is against what Solo is doing. Although he has his last issues with Roman, he would clearly rather side with Roman Reigns against Solo.
All that is needed is more drama enough to get Jey emotional and he'll come and help Roman and Jimmy. Eventually Jey Uso will be forced to fight against Solo because he has refused to acknowledge Solo Sikoa and Solo will not like that and probably will attempt to do something about it.
That's make Solo a common enemy to both Jey and Roman and I believe that's how they'll join forces.
