#3 Lana ends up all alone
If Bobby Lashley is actually using Lana and Rusev as a way to get people to pay attention to him in order to propel his career to new heights, and Rusev refuses to forgive Lana and doesn't take her back, where does that leave the 'Ravishing Russian?'
Alone.
It's a dangerous game that Lashley and Lana are playing. That could be an important word. Is Lana playing Lashley? Is Lashley playing Lana? Could they possibly be playing each other and neither of them realize it? No matter what the case, if Lashley is using Lana, then she could be left out in the cold.
It is possible that Rusev could take her back. It's been made clear during the entire storyline that, even though Lana is hurting him very deeply, Rusev is still very much in love with his wife and wants to be with her. He could accept her apology, they could take a break from the rigors of the road, and come back revitalized as a strong team, maybe even with the return of Rusev Day and Lana Day.
Probably not, though. Lana may find herself without Lashley and without Rusev. Would she disappear from TV for good? Would she find a new man to accompany to the ring? Maybe she could go back to training and become a wrestler. Lana may have to consider her options, if neither man will have her.
