There's been all sorts of rumors about how this storyline is going to play out. Personally, it looks like the writers are content to keep this going as the Bellas dominating the division and no one helping Paige. If the goal is to have Nikki beat A.J.'s title reign, whatever. That's petty on their part, IMHO. I understand the Bellas are the featured attraction of the division w/"Total Divas," but don't marginalize the Diva's division just to keep them looking good.
But... it it's World Wrestling ENTERTAINMENT, right?
Whatever the reason, I agree that this angle has been very poorly drawn out, with tons of loopholes and flaws. I'm a big fan of Paige (not much on the Bellas, but I'll say they have improved a lot), and I hate to see Paige being drug through this angle. But, she's the top face Diva right now, so there's that. I'm hoping that a payoff will come soon.
So, Captain Obious here - the fact that only Alicia Fox has claimed sides so far means that they will likely put two Divas with Paige for a 3-on-3 scenario at some point. But who will Paige's partners be? Let's see...
When they showed Naomi and Tamina backstage watching, making a point to say that they've claimed neutrality in the situation, that made me think that they will become part of this in some capacity. Why just single out those two? I don't think the writers would turn them face after Naomi just turned heel. But nothing really surprises me with the booking of the Divas division right now, so it could happen. IMHO, they need to keep her as a heel and a threat to the Diva's title. But the whole "the enemy of my enemy is my friend" thing could be put into play, since those three have axes to grin with Team Bella.
I doubt it will be any of the other Divas on the roster, because honestly, no one else matter right now. The only one that's not in this equation that could help it is Natalaya, but she seems to be out of the picture helping her convalescing hubby (Best wishes, TJ).
As for the belief that this will mean the long-awaited call-up for Charlotte and possibly Sasha Banks to the main roster from NXT, I REALLY hope that's true, and I believe that happens at Summerslam. A big stage to finally bring up NXT's two best women competitors. Sasha can still be the NXT Women's Champion and be called up, a la Kevin Owens. But, she'd have to drop it to move up full time. But, maybe they bring them up at Battleground. With this current booking mindset, who knows?
As always, I reserve the right to be wrong...
