That's because Jane (in blue) has it in for Shane D (in white) and Nina (in yellow) comes to the rescue.
If you have ever seen Nina and Jane brawl, you know that they bring a lot of 'enthusiasm' to a fight, whether it's in water or mud. It makes no difference. Poor Shane looks at times like she's caught up in some sort of tornado! Check out the video preview. The action here may not be very revealing, but is sure is fun!
