What makes the world of wrestling more entertaining than a regular bout? The plot twists, of course. It's no news that the fans of wrestling are often treated to surprises, as fan-favorite stars return and make shocking appearances. And if the loud cheers that fill the air of the stadium every time a wrestling star returns are any proof of how much the audiences love these surprises, then rest assured, there's plenty other proof! And we just got reminded of the same when most recently, Nikki Bella made her surprise return in the SummerSlam 2016.
