According to PWInsider.com, the original plan at WWE Money in the Bank was for Becky Lynch to turn heel and attack Natalya, but the opposite happened instead. No word at this time as to why WWE changed plans.
In related news, there has been speculation that Natalya might be finishing up with WWE when her current contract expires, due to the situation with her husband Tyson Kidd not being able to wrestle. Kidd’s in-ring future is unknown at this point, and while it’s purely speculative at this point, there are people in WWE who expect Natalya to leave when her deal expires.
